Welding Equipment Different Process by Used

For welding equipment consists of a material or device used for various purposes. In particular, used to join what is called the processes such as arc, resistance, laser, electron beam, stud and orbital welding. Among the list of processes that are served by the equipment used is the wave soldering and brazing techniques. Welding machine and the system can operate through the use of welding power source. Occasionally, someone may need to facilitate the welding controller destinations served by the machine. Fortunately, there is also a complete system with a surface or cutting machines, torches, feeders, cables, robots, positioners and feeders. To find out more about welding equipment used, the following is an explanation of the process where it is being utilized.

Arc welding method
Arc welding involves different aspects of welding including MIG and TIG. MIG welding stands for Inert Gas Metal Welding. At the time, it can also be referred to as welding or MAG welding Metal Active Gas. It is regarded as one of the arc welding process that is very popular because of its versatility. It makes use of various forms of gas to complete the process. This list includes pure carbon dioxide, pure argon gas or a mixture of two chemical components.

Another process known as TIG Welding is highly dependent on new or used welding equipment. TIG stands for Tungsten Inert Gas. This process is called as such because it uses tungsten as striking an arc between the workpiece and welding electrodes. Inert gas used in these types of arc welding process is argon. When compared to MIG Welding, this one is slower and usually more expensive. Welding has other processes that are included in the list. People such as flux cored arc welding, gas metal arc welding and resistance welding seam is included. Spot welding and shielded metal arc welding are also popular categories in the welding process.

Other welding processes
In addition to arc welding process that uses welding equipment, welding friction is also considered to be part of the list. An example is the hot plate welding, plastic welding, electron beam welding and Oxyfuel welding. No matter how diverse this process, there is a common denominator applicable to all. It is a fact that when looking for a pre-owned equipment for welding, the machine must be able to meet the corrosion resistance, some of the operations and water coolers. Of course, heavy-duty engine with engine driven generators are highly qualified to fulfill this process.

Best Welding Machine of Tig Welder, Arc Welder & Plasma Cutter

Welding equipment is essential for a good welding process and the industries that the welding use requires welding equipment and instruments. Here, in this article, we will discuss three of the best welding machine and its use. They are nothing but the tig welders, plasma cutters and arc welders. Three welding processes are widely used in many industries, for example, if one looks at the TIG welding, welding is a process that allows the quality of the weld is stronger and more high and most of the engineers prefer gas tungsten arc welding, since has suitable properties and low hydrogen with good mechanical and chemical properties of the base material. Arc welding process of welding is the kind of day, old but still very popular because of their welding characteristics.

Plasma cutting utilizes new technology and cutting of steel and other metals of different thicknesses. Ok, now move on to the welder and use, and we also see from last to first. We begin with a plasma cutter, modern industries that rely on heavy metals and metal alloys and is very strong and at the same time, also has some of the weak. To cut the metal is not so easy and even had to cut so as you can just cut and manipulate the metal. To all these questions, the new engine was introduced and is known as a plasma cutter. When you look at what is conceptually very simple and comes in all shapes and sizes. It is compact and is mainly used in auto shops and auto manufacturers. When you buy a welder, consider how you did and look for one that has cut off most of the time. If you are looking for this machine to consider what they would cut out most of the time and should not weaken the metal you are working with most of the time. Verify the capacity of the machine to buy and also obtain a cutting machine which cuts the plasma more quickly than others. The myth that a welding arc, it is more expensive and may be used only by large companies, but it is true, arc welding machines are now much more accessible and can be used by all industries. Find a bow that is bought and watch demonstrations and learn to use so you can get the type you need. Last but not least is the TIG welder and welding consumables like TIG depends tungsten electrode and a special soldering iron can not be found in many shops and with the help of a welder can weld two pieces of different metal thickness and can be welded together without using a filler material.

So when you buy this computer, look for one of the best quality and the good and the price of a piece. Get a good machine for welding and secure.

Welding Machine Work Made Easy

Needs of the industry is increasing every day and almost all sectors of activity using the technique of welding in one way or another. Welding process has become so important that the company employs welders who have a thorough knowledge of the operation, the capacity to read welding symbols and blueprint of advanced work skills. This is the basic characteristic that companies are looking at a welder. But the most important thing is how to handle the engine welder and how it operates it. Specific protection measures must essentially be taken to ensure that the welding process is done safely and efficiently. The following steps will help the process of welding easier. The first and most important thing to consider is the place where the welding machine candidates will be placed. It is advisable to keep the machine in a dry area where proper air circulation and there is good ventilation. Air circulation is absolutely essential because for welding all kinds of chemical fumes will be emitted following the technological process. Smoke as it is dangerous and very risky for the health service. If at all possible do not open access, the engine would have to have special vents to be placed very close to the engine. So be sure air circulation to an extent. It is also important to ensure that no flammable materials near the welding machine. Substances such as paints, solvents or other chemicals of flammable nature increases the likelihood of accidental exposure.

The important thing is the cleanliness of the area where welding occurs. This area must be cleaned before the welding process because any traces of paint, oil, rust or other impurities may be able to reduce the efficient functioning of the welding machine. Here the need for protective clothing that appears very important. Welders operate the machine basically have to wear protective gadgets like protective gloves, fire resistant, apron and a special helmet with protective goggles. Such clothing will help welders to prevent exposure to radiation, splashes, droplets, or smog that occurs during the use of welding. Above all, one more important thing to note is that all the welding machine settings must be set according to the characteristics of the metal to be welded. If nothing is done, then burn out or bow low penetration will occur.

Welding machines are usually purchased for industrial use but if you are an amateur or a novice welder, you do not need to buy the machine. Evaluate the work before setting out to buy a welding machine and welding equipment. Compare the level of investment possibilities along with the desired result. If you only do occasional welding, the welding machine hire more than enough. But if the welding machine is almost 60% of the activity, then it is better to buy one. There are many other cost effective options such as buying a used welder that can be relied upon as an obligation of the machine.

Overview of Gas and Arc Welding Machine

This article sets out to describe the various types of welders are used in industrial metal fabrication and applications of each. Welder can be divided into two categories: those who use fire to heat sources and the use of an electric arc. Flame welder consists of four main parts: compressed gas cylinders, regulators, hoses, and handles. Gas cylinder containing a fuel and oxidizer. Acetylene and oxygen are combined fuel oxidizer most common, but many people use propane for fuel because of the relative instability of the Acetylene. Each cylinder has a manual valve which when opened allows the gas to flow into the regulator. Each gas cylinder has an adjustable regulator that reduces gas pressure from the higher cylinder pressure to a pressure consistent. Set the regulator allows adjustment of the flame. The regulator is connected to the butt weld with a rubber hose. This Handbook contains the on / off for both acetylene and oxygen valves, and threaded adapter to allow attachment welding range, brazing, cutting and tips. Because of this design gas welding outfit is the most versatile - with the right accessories almost any operation can be completed. A skilled operator can weld thin metal with precise control of the welding flame. Gas welding can easily result in contaminated welds when the operator is not diligent and the flame is not set correctly.

Arc welding machine is broken down into three categories, based on the electrode material and type of protective gas. SMAW is the most simple process, which stands for shielded metal arc welding. An electrode holder clamps long metal electrode coated in flux mixture. Arc is struck between the electrode and the workpiece. Metal electrodes deposited to fill the weld, and flux of shielding gas to burn and create. GTAW welding, or more commonly referred to as TIG welding, Gas Tungsten Arc Welding stands. GTAW welding uses inert gas, usually argon and CO2 mixture to prevent the weld from being contaminated by oxidation. The Tungsten on tungsten electrode which GTAW stands used to support the welding arc. Workpiece is the negative side of the circuit, and the tungsten electrode is formed on the positive side, which is contained in the handle, called a 'torch'. The operator manipulates the welding arc voltage using a foot control pedal and by varying the distance of the torch from the work. Welding is filled in using welding rod. This technique is similar to gas welding. GTAW welding is slow, but allows for a high degree of precision and the welding of exotic metals like titanium. Stands for GMAW welding gas metal arc welding, also known as MIG welding. Instead of tungsten electrodes and filler rods separate the two combined. A metal electrode continues to eat a good idea to support an electric arc and add filler metal to weld. Inert gas welding shield and prevent contamination, such as in GTAW welding. GMAW welding fast and versatile. FCAW flux cored arc welding stands. Feeding mechanism employing FCAW GMAW welding electrodes together, but instead of inert gas to protect the welding wire containing flux, which when burned creates clouds shielding gas around the weld.

Welding Machine Used Various Industries

People are very aware of the terms TIG welding as one of the main types used by many industries. Let us understand tungsten arc welding in detail. This is the type of fusion in which the arc is formed between the tungsten electrode and the condensate brittle metal. Produces a high temperature tungsten and has a high melt strength and superior electrical characteristics, which is one of the reasons that used for the electrodes.

Even if the TIG welding may not be suitable for all types of business needs has many advantages. When managing the business of manufacturing of consumer products where appearance is one of the most important principal, then an option should be TIG. Some works that need to code requirements, such as pipes, jobs in nuclear and high-profile consumer on a regular basis requires at least the main welding of pipe joint connections for TIG to be efficient. Generally, a MIG welding machine is not considered a better quality as a TIG welder and is one of the widely accepted in the welding technique. TIG is generally used for higher quality bonds. For example, a small masterpiece of a car engine aluminum of 3.2 mm in the MIG will be able to do the job faster, but certainly more than the TIG process engineers chosen for its accuracy.

When a person must include materials ranging from five thousandths of an inch, then it is true that the usual method may be insufficient and even a MIG welding can not be applied exactly as much heat in the metal. When it comes to a combination of heavy metals, go for the MIG welding or joining materials, because they can more quickly. The choice at the time of TIG welding, it is necessary to identify the amount of energy and the density required for the process. It 's also important to know the volume of work currently in hand is worth it for TIG welding. The next thing to consider is a resource, if you need an AC or DC.

Researchers and experts say there are two metals aluminum and magnesium that best integrates with the use of AC power outlet. There are many other metals such as stainless steel and are often blended with direct current. When it comes to the integration of a variety of different metals, one may use a combination of AC / DC machines. TIG welding is used primarily for welding different types of aluminum alloy and stainless steel, where quality is given more importance. It 's mainly used for the construction of aviation, chemical and nuclear industry.

Researching & Purchasing Welding Machine

Are you new to welding and welders are interested in buying? If so, a number of factors you should consider choosing a car for you. If you're like most people, the first thing is its price. While price is important, other equally important if not more. Taking time to evaluate all options based on what best suits your needs, you can get more satisfaction, pleasure and the use of welding machine is right for you.

The first thing to consider is what you want with it. Determine the size and type of metal, mostly welded. Requirements for the welding of aluminum engine is very different from the thickness of welding of thin sheet metal. Please note that when it comes to price, more modern, more money.

It 's also a good idea to take into account the cost of consumables. If you are considering the type of arc welding - Metal Inert Gas (MIG) or tungsten inert gas (TIG), - you must know the type of gas needed for the type of welded metal. Recently, gas prices, in particular, the helium gas containing layer is increased dramatically. On the other hand, a stick or arc welding does not require a protective gas and can be cheaper in the long run. Along with the gas-gas, pay attention to the prices of welding electrodes / cables, tips, nozzles and accessories specifically for this type of welding you are buying. At the time, could have a significant impact on operating costs associated with the device.

The power that was available to perform the soldering iron is a very important factor that should not be overlooked. Welding with high power consumption, and often requires more energy than was available at the time of use. If you do not have enough power to ensure that only one, you must update the service, which will add to the total cost. An alternative to what is the engine-driven welding. With fuel prices rising, however, this may not be the most effective solution.

One of the best advice is to consider using a soldering iron. You'll often find a welder for sale, and there are many good reasons for this - the old welder, was built at the end. Welder is really easy as long as you want. The welder is often available at a fraction of the cost of a new well.

These are just some of the many questions you need to do before choosing a welder. As you can see, is much more complicated than driving a car in a big box store and buy what is on the shelf. If you educate yourself before buying, you save money and ended with a soldering iron, is much more useful in the long run.

Welding Machine Portable

Welding operators who still have to move from one place to another. A portable welding machine is a must with some major crops because they have to move and was in doubt where he would be required of the next hour. It is a known fact that the right kind of equipment for the job can save time and increase productivity. These units are useful and advance and suitable for all applications, production, maintenance and special purpose welding.

To give the volts and amperes are required for their portable welding machine connected to the generator. For them to work they require a prime mover, electric motors or fuel-powered engine. With some areas having alternating straight and the other there can be many problems with the device. So without the right set up the machine will not work. To eliminate this problem, today the main propulsion engine driven, fueled by gasoline, kerosene or natural gas provides the best solution for a consistent and stable electricity.

Arcon develop one of the most rugged machines and reliable portable welding. Arcon Welding LLC was founded in 1999 as today is the industry leader. Workhorse series of portable arc welder is considered the most reliable stick, TIG, MIG and Stud welder. It is actually called a professional day-to-day companion welding. This is the power unit moves only constant in the market. It is built for TIG welding with industrial robots with time proven SCR inverter power supply type. It is lightweight and weighs only 80 pounds. It features a built in circuit breaker and provide thermal protection zone 5. It is corrosion resistant and has a smooth weld.

Horse stud by Arcon is the first portable unit on the market capable of welding up to 5/8 inch studs base filled with a capacity of 1200 amps of welding current. It welds steel, stainless steel and aluminum. It weighs 80 pounds and comes with a five year warranty against corrosion-related failures in the natural environment. This has set the current digital time and to withstand the heaviest of the natural environment features a solid fiberglass case. Arcon has a welding machine to meet the different needs and operations. They have chosen a combination that can be best used for fine welding conditions.

While choosing a portable welding machine is important to understand the nature of the work. A MIG device has a greater speed but will TIG weld better weld quality. For highly visible consumer product manufacturing TIG is best because it gives a better performance. MIG or Memory Stick preferred unit as thick as the metal they put more heat into the metal. A simple MIG machine is good for the hobby they do not need high-tech advanced TIG machines. Select the machine depending on your needs and nature of work.

Titanium welded tubes for aircraft

The evolution of modern superalloys has coincided with the evolution of gas turbine engines for aircraft industry. Level of development of new alloys has been rapid and, in many cases, exceeded the co-joined development techniques. Traditionally, especially in the field of high temperature alloys have been in force, breaking stress, and oxidation properties. Metal joining has been treated as a separate problem with the welding and brazing engineers are usually required to design procedures and techniques to join any new alloy after it has been developed. This resulted in excessive costs for the fabrication of several alloys for metallurgical variations unpredictable and uncontrollable causes problems such as cracking during welding. Titanium is often preferred for the flight tube welded.

Welding superalloy.
Although many difficulties, welding has been and will continue to be one of the main fabrication technique for aircraft engine components and ground. Welding allows the manufacture of subcomponents economic size with essentially no additional weight and moderate cost. Welded joints causes a relatively small reduction in the ability of the service if they are placed in a critical location. Tolerance that is able to hold on welded components are close if the right fixtures and welding techniques are used. Skilled welding allows the joining of titanium welded tubes for pneumatic, air conditioning and waste water systems on the aircraft.

The main problem encountered in superalloy weld cracks and fissuring. Planar separation of the crack is visible to the naked eye. A fissure, on the other hand, is a small gap that is usually only detected by metallographic examination. Prevention of disability is one of the most challenging problems in the welding of superalloys. Many superalloys, such as the foundry 713C and 131 900, has a high sensitivity fissuring like that is not possible to make crack-free weld fusion.

The second problem associated with the welding of superalloys is a decrease in mechanical properties. Generally, the technique can be used which does not cause a significant decrease in tensile strength or yield, however, the ductility of welded specimens practically always reduced. This is because the structure of the solidified weld metal is a separate and less resilient than the equivalent wrought structure. Separation that occurs on compacted weld metal can also cause a decrease in resistance to oxidation. If the high-electron-vacancy elements separated on solidification, they could lead to precipitate embrittling phases during welding or after put into service. Each alloy is to be examined individually to assess the degradation in properties that may result from welding. Postweld heat treatment can help in reducing segregation, but the effective heat treatment is often difficult to perform on the big engineering.

Area in the heat affected zone exposed to high temperatures and excessive grain growth, solutioning and reprecipitation of the carbides and precipitates. These changes can cause damage to property, such as corrosion and oxidation resistance, and should also be evaluated on an individual basis.

Weld reinforcements, ie, welding and underbeads overbeads, should be avoided in situations where fatigue is a failure mode. Fatigue strength reduction factor of 2.25 to 2.50 have been reported to underbeads welding. The best method to avoid the problem of fatigue is to lay the weld joints in low stress areas.

Welding Process
There are 45 different welding processes. In the most common welding superalloy is shieldedmetal arc, gas tungsten arc, gas metal arc, resistance, and the electron beam. The purpose of the welding process is to generate heat in the local area and thus lead to melt and join the two pieces of metal. Although the process is significantly different from each other, from the picture they are just different ways to produce localized heating.

Pan Uni Plastic Welding

Plastic welding is the ability to take two pieces of plastic and weld them together. This is the type of welding to be performed on children's toys, garden furniture, automobile parts and other types of plastic utensils that you might use everyday or commercial. Types of welds used to join thermoplastics when they are heated and under pressure. Generally the pieces are fused together with a filler material, but some cases do not require a filler material. Plastics often have a shorter lifespan than most types of products because there are so many things that can go into how it is maintained. Elements of nature like cold weather, UV rays of the son or chemical contamination can cause damage to the plastic. Plastics can also receive damage if hit hard like the bumper cars or other hard surface, but the purchase of new parts can be cost prohibitive, this is if it can be a good idea to fix it instead.

There are different types of plastic so it is important to know which ones you work with to ensure that the proper use of welding materials. This is a good idea to understand the difference between thermoplastics and thermosets thermosets can not be welded due. Type of plastic that need improvement will require different welding rod and if you're using the wrong rod to the plastic you need to improve, there will be no ties. Materials such as Polyolefines has a lower surface energy, so this means they can not usually be repaired with a type of adhesive or glue. There is a special group Polyolefine adhesive that can do this job.

When you make improvements in the plastic there are usually two types that you will come up - you'll either have to repair cracks or damaged parts. If you are looking for crack, it means that there are several types of stress that affects the inside of the material you use. This means that you have to fix the cracks and make sure it does not continue through the piece.


There are several types of plastic welding. Some of them are:

1. Hot gas welding using a welding gun that has an electric heating element in it that generates the heat from the hot gas. 
2. Hot plate welding using a hot plate between the two surfaces being joined. Ultrasonic welding uses high-frequency acoustic vibrations to weld the pieces together. It was placed under high pressure and then exposed to vibration welding is completed. 
3. Spins in which the friction welding used to weld the two parts of the cylinder as the parts are played. At any given time stopping the rotation and the weld is complete. 
4. Vibration welding is required for the plastic pieces and exposing them to a frequency called the amplitude. Two are under pressure which causes friction that generates heat. 
5. All types of welding work on plastic and they are directed to work with a variety of polymers.

Details About the Stud Welding

What is stud welding?
Although many people believe that there is only one basic welding applications are actually involved with welding applications. A stud welding interval in which the screw or nut welded to a piece of metal formed. This may help with automatic welding machine feed screw with the welder.

Stud welding, soldering or bonding, Stud comprises a flat plate with the aid of a screw as an electrode. The polarity selected will depend, for special applications welder of the type of metal used is. For example, aluminum generally requires a positive electrode current, or DSPM, demand for steel during the negative electrode DCEN or DC. Grains used in soldering pins (or arc welding) usually have a flange with a kind of small protrusions that are melted during the formation process of welding. Forced, A-threaded part of the weld nuts also help to form the desired welding. Another aspect of this application is the use of flow, which is like a sleeve. Ring is ceramic sleeve, to concentrate the heat generated to prevent oxidation and maintain the desired liquid metal in the weld area. A particular type of said welding process for welding, welding of the traditional, since it requires no flow. The method uses a capacitor current arc and the welding time between 1 and 6 milliseconds only. Since then weld the bottom of the capacitive discharge welding, the welder can concentrate complete a link with some real needs, and oxidation to produce heat.

What stud welding?
Stud welding system stud welding as part of this application in an efficient manner. The key size varies from 14 to 3/8 to 5 "diameter can vary from 1/4" "or more in length, and from the condenser of bits at the end of the welding machine has two purposes. Timing. Suggestions such as a timing device, the buttons on the base material is welded spot. Disintegration. Soldering tip destroyed when the trigger end of the welding gun and welding are fused to strengthen the base material.

What Arc?
Pin arc usually with a ball at the end of the aluminum brazing powder loaded, which helps show the welding process. These buttons are only part of the stud welding system, and may from # 8 to pin 1 of the range "diameter 1/4.

Staying Safe While MIG Welding

It is common knowledge that the security aspect should be the paramount concern when it comes to welding. Welding operation produces sparks at great risk of fire accidents and the things in the surrounding area may be able to get turned on. MIG welding, although it generates more heat and light are harmful, may still be completely safe as long as you follow all safety precautions is important. As a first step, you must be permanently fire extinguishers near the welding area. It is better to have a CO2 type fire extinguisher when welding. Water extinguishers may not be appropriate in the welding shop because you will stand in the middle of a whole lot of electricity. Make sure there is adequate ventilation in the welding area so that fumes are not harmful to strangle you. Wear either a mask or respirator if you'll be welding for a long time.

Light generated by each type of weld incredible bright and can burn eyes and skin like the sun if you do not adequately protect themselves. Therefore, the first thing you need before you start work welding is a welding mask. It is better to use auto-dark welding mask because it is safer if you are going to do the welding for long hours or working with metal often. Unlike the manual masks, auto-dark welding mask allows you the freedom to use both hands to weld, and do not bother about repeatedly adjust the mask. Use welding screens to protect others as well around the weld area of ​​blinding light.

Do not indulge in MIG welding if the water is in contact with you or there is a pool of water around your weld surface. It is necessary to prevent any possibility that may be of electricity. Due to excessive heat, skin and hair can burn and therefore need to wear long-sleeved shirts and long pants are not flammable without a cuff. Use a leather welding gloves and effective eye shield or welding hood. Some people opt for the welding of thin gloves for better dexterity of both wrists and palms - but for your MIG welding gloves can wear whatever you feel comfortable with.

The skin will not only protect your skin from the heat generated by welding, but they will also protect your skin from UV rays produced by welding. Please remember UV burns happen suddenly and spread quickly, and you should be extra guarded. If you can not wear leather, then you should at least switch to wearing cotton clothing. Plastic fibers such as polyester and rayon should be carefully avoided because it will melt when in contact with molten metal and the positive will burn you. Most of the cotton will make a hole and not burn out or do something fatal.

Never wear open toed shoes or synthetic shoes that have toe webs on it. There is all possibility of hot metal dropped straight down and burn a hole through the top of the shoe. Wear leather shoes or boots, or at least cover your shoes with a non-flammable material. Please be aware that materials such as sawdust, paper or plastic bags around the welding area can smolder and burn - so keep welding is neat and clean and free of articles on fire. Your attention will obviously be focused on welding and would not be possible for you to notice what is going on around you even if something suddenly caught fire.

Automated cutting and welding to metal fabrication company

Cutting and welding automatic probe can be an excellent way for a producer of metal to reduce costs and manual efforts in manufacturing operations. Consistency is necessary for critical automated welding can be obtained by creating an automated work station in the production process. Cut-to-fit technology for both cutting and welding of car parts carried out with extreme precision. This prior art eliminates the critical issues for welding, although it should be done with zero drift. First, this automated process that measures the actual size and shape of the metal tube will define the necessary holes and cut to weld the accuracy of which is not possible manually. Finally, the automatic welding welding the parts together with a complete penetration is difficult to achieve by hand.

Place a weld line to connect the two straight sides of steel with square corners can be a simple process for both manual and automatic welding. The task of welding a circular shape a bit afraid, "if done manually or by robotics Sometimes the shape is not exactly whole or in part can be" round ", but even a well-formed ellipse, making the process even more difficult. Sometimes they form a tube-shaped object to weld a little "outside all year." However, the object must be paid, no matter the form. The fact that the "return" of the weld is good from time to time "outside all year," or measure otherwise can cause a lot of extra work and expense of cutting and welding, if the process is done manually.

In many cases, the weld quality is not only mandatory, but is a need for such "soft edges" welds are performed to build things such as an oil well blow-prevention device, the high pressure tank of gas, and pressure gauges mounted on the pipe. Now all the boring guesswork has been removed from the weld. Using the arc tracking via automated robotic welding technology is now equipped with tactile sensor devices that allow the determination of the exact shape and size of the external object "rounded" to weld to another metal object. The "sense" the shape and dimensions of the structural tube before welding begins. Follow along to define moving along it and determine where deviations in the joints is based on the geometry of the object or effect of heat.

Monitoring can also specify the width of the boards so that a proper weld penetration can complete an operation requested by automatic welding. The robot moves around the outer edge of the tubular object to be welded. Thus the shape and size of the object is "read" by "eye detection." This geometry is perfect or imperfect to be welded are stored in the memory of the computer controlling the cutting and welding. Despite Cut-to-fit technology is designed for cutting and welding of pipe-shaped objects, automatic welding technologies can be programmed to address an irregular shape, which is consistent in size and shape.

After all the shapes and the dimensions of the tubes were collected, plasma cutting torch at the end of the robotic arm to verify the exact manner in which the surface of the welding carried out. Plasma cutting torch and then penetrate through the thinnest part of the base plate and cut a hole that perfectly matches the size and location verified. Cutting process is aided by the addition of oxygen at increasing temperature. Due to the increased temperature of the molten metal is withdrawn becomes 'wet'. This makes it possible to fall from the cutting surface with rain are minimal. This will leave the surface, cutting the pot clean, soft, very good for welding.

Automatic welding process begins with some welding lines welding torch to verify the previously defined by a plasma cutting torch. In many cases, preparation of surfaces to be welded is very inconsistent. But because the oxygen used for cutting, welding surface is the best that can be achieved. The actual penetration welds, the welds are defined exactly full faces in the path specified. Complete and arc welding Adaptive Tracking was always available, in a welding robot incredible. As you move along the path of the torch, adjust the discrepancy in the supervision of the centerline of the slot arc welding. Furthermore, there is ample compensation for the welding groove filled with adaptation to ensure that consistent high quality welds at all times.

Welding Equipment Can Avoid Risk

Welding is the process used to melt the metal and joins them with a stuffing material. The combination of high heat and pressure are generally used in this whole process. This is potentially a dangerous manufacturing procedures. Welding can be carried out in different forms because it is one important part of industrial applications.

There are several different energy sources such as gas flame, friction, electric arc, ultrasound, laser and beam the electricity used in the welding process. Power supply, shielding gas, electrodes, rods, welding and arc are some basic requirements to complete a specific application. Because it is a dangerous process there is a high risk involved in it, then the defensive security equipment such as masks and helmets are very important. This gear is the most essential requirements for the security of welders because they are the same people involved in welding.

Welding is a complex problem so that a complete examination should then be able to get rid of only one risky environment. All those people who engage in this activity continues to open contact with an electrical fire, and therefore much higher chance of injury. This process involves the possibility of burns. To prevent injuries so severe, protective gear such as leather gloves are durable and long sleeves dress is entirely covered thick are used.

Electrical fire can cause facial injuries and a variety of eye damage to someone else, but welder can prevent themselves with defensive masks, goggles and helmets. All protective equipment specially designed by a dark lens or defensive & faceplates. Helmet or sunglasses can reduce the harmful effects of ultra-violet rays which are directly derived from sparks and flames. There are many opportunities to deal with toxic gas welder and toxic particles or smoke can create breathing problems.

There are several easy access to commonly used operations such as arc welding, TIG & MIG welding and gas welding. To make the fuse arc between the electrode and the base material using a power supply arc to melt the metal at the point of the fuse. When it comes to protecting the welding area, type of inert or semi-inert gas which is usually known as the packing material should be used. Direct or alternating current may be used in this application. In the case of MIG & TIG applications, a constant and fine wire electrode which passes all the way through the welding gun. Continuous electrical energy and DC power is typically used in these types of activities to join. At first, they are used for this type of aluminum metal fuse. In the case of MIG applications, electrode wires consumed to create a bond. During the entire process, to avoid nitrogen and oxygen in the air of pollution welding, gas needed defensive.

Popular Sheet Metal Welding

Welding sheet metal bender popular in the repair, metal finishing and art are very wasteful. Welding sheet metal takes much patience and skill training on average. Welding procedures used may be best determined by a particular project but can also be determined by the available tools and welding experience level. The three most common methods of welding sheet metal is gas welding, MIG welding and TIG welding. Of the three, TIG welding is more often used as a TIG welder is usually not accessible to the gas and MIG welder.

One of the advantages for gas welding is that the soft metal sheets stored during the welding process, so the novice welder will find material that is softer and easier to work with. MIG welding is just the opposite; materials that are difficult to work with, harder and is known to shrink. The best metal welding combines the two processes to achieve desired results. My advice is to work with a first gas welder to get the hang of it, and then slowly introduce yourself to the MIG welding process, the test in less visible areas. Will weld a gas welding expert as much as they can and then in the MIG welding is more difficult to reach. The important thing to remember when combining both procedures prior to welding is a welding gas welding and MIG welding is never in the opposite order.

For welding with gas, use a small tip on your welder and be sure to have all your settings correct. You do not want to try to weld to the pressure too much or too little, so it's worth to pay attention to your equipment while you weld. If you hear a popping sound, or too many redundant, you need to make adjustments to your equipment. MIG welders with less experience tend to complain about not being able to see their work as they weld. So make sure your face mask in good repair with clear lenses, and has always worked in a lot of light.

Equipment other than the welder also need to weld sheet metal safe and successful. For security reasons, you need heavy welding gloves. Welding gloves will protect your hands from sparks or shards of metal sheets that can fly during the welding process. You will also need a special mask for welding; best model has a light sensor attached to the mask. Tool-wise, you need grinders, wire brushes, sandpaper grit in different, vice grips, clamps, pliers with rubber grips on the handle, and hammer sheet metal. None of the items are optional. They all make sheets welding easier, and safer, and ultimately will make for a job well done.

If you want to improve your welding metal sheets and then head on over to my blog on TIG welding of metal sheets which I am happy to share my decades of experience. Tips that will save you time and headaches.

Reap Rewards & Weld School

Now that you've built yourself a Buzz Box, you might want to see what this house was built arc welder can do. Your first attempt at welding might seem like you wasted a lot of time and money to build a piece of trash who obviously did not work. Rest assured, you have a welding machine capable of producing welding quality with proper welding electrodes and a little help from you.

Before we begin, let's get an understanding of what happens when you strike an arc with a welding electrode. The size of welding rod, the electric current and the thickness of the plate determines the fusion welding (adhesion) at first. In other words, large-diameter welding rod on a thin steel plate will blow right through it. On the other hand, a small diameter rod welding on thick steel plates may not start the arc and, if you do, do not weld will fuse to the steel, but simply lying on the surface of the steel plate. This is where the heat comes to your aide. Heat allows you to use a small welding electrodes with thick steel plate.

Prepare the bevels and Land
Be prepared to clean steel plate to put on your safety equipment, welding helmet, welding gloves and a dust mask for particulate matter. "Junk In, Junk Out", is what you would get if you do not prepare for the welding of steel plates. Never weld through the garbage, rust or scale if you have the means to clean steel. Bevel should approximate 45 degrees with the ground "1/8 (even) at its base.

Set Root Gap
When the bevel has been applied to the second steel plate, turn them face down, set the root gap (I use a metal stub of my welding with a welding electrode) and employ a place to tack welding them into position.

Position in Steel Plates
Now that the plates had been cleared, sloping and affixed, clamp the steel plate in a position of comfort and prepare for root pass welding. Collect your welding supplies, gas and torches for preheating, welding electrodes, a stinger and you Buzz Box.

In the Heat of Steel Plates
It's never a bad idea to heat, in fact, virtually every welding job I do professionally demanding preheat temp of 400 degrees and above. You'll be amazed how easy and how well the bow attacks welding rod burns, significantly improving the quality of welding. Remember, once the steel has reached the heating temperature, the temp should be maintained throughout the procedure until all welding is completed.

Roots Run Pass
Extra care should be taken when running the root pass for root If the pass has a good fusion and waterproof, the rest of the welding is only a formality, especially when welding pipe. Make sure the joint is good and hot and you feel comfortable during the weld. Comfort means of control.

Run The Passes of Contents
I dub the "Welding Mindless" because you burn the stem after the stem until you complete the pass. I run a weld in steps starting with the root pass, through the intermediate filling and fill finish. As you increase the weld, giving special attention to tie on the sides, this is your weld strength.

The "Cap" pass is where you let your skills shine. They could be at least one or as many times as necessary to cover the full you only welded joints. This is your signature, so take your time and make them straight and the right height. Grand final 'of this episode is to change the finished dish, grind out the root opening to the metal without defects, heat the steel plate, fill the joints and run a hat, you're done.

The procedure is simple to use your Buzz Box is the basics of welding all. Welder welding in many career doing a lot of welding services and welding work using this technique. They produce consistent quality welds with welding wire or electrode welding and you can too.

Pros and Cons MIG Welding

MIG welding, as most of us are aware, is a semi-automatic arc welding process in which a continuous, consumable electrode wire and shielding gas are fed through a welding gun. At the end of the pistol, no contact tip to pass power to the wire. Both wire and shielding gas to create the weld is activated when the operator pressed the trigger gun.

Excess MIG welding
MIG welding is quite popular because it is easy to learn and requires no special skills. Even the first operator will be able to achieve good welds with minimal practice. The people support the MIG welding because it is much faster than Stick welding and save time. Thus the operating cost is lower than MIG welding stick welding because it saves time. MIG adjust the length of the electrode is limited and this allows for the weld again with fewer interruptions.

In addition, there is also no filler metal waste and, in general, the thinner material can be welded with MIG is much easier than stick welding. One reason many people like MIG welding is MIG welding is a process for neat and does not require chipping slag as in Stick welding. MIG welding would make for a very convenient connection and installation of spare parts and there is very little stub loss as a continuous filler metal spool.

MIG welding is a versatile and capable for a variety of applications, including - trailer hitches, auto body repair and restoration, agricultural / farm equipment, household projects, repairing wagon wheels, bikes, etc. This type of weld requires less time compared to the type of welding process.

Cons MIG welding
MIG set the high initial cost and considering the shielding gas regulator - although some MIG welding can be performed with flux core and protect themselves without gas or regulator.

It is indeed a fact that all types of materials can be welded with MIG machine. But, in the MIG process different materials require different wire and gas. For example, mild steel can be welded with either self-shielded wire or a gas mixture of CO2 or CO2 but aluminum requires the use of Argon gas.

It is not advisable to weld through dirty material with MIG machines. It is said one should always weld the cleanest material possible, so for best results scrape paint, rust or other debris in which the weld is being made.

There is no denying that the MIG welding equipment is more complex, expensive and less portable welding gun and difficult to maneuver. Filler metal may become tangled in wire feeder make the operator feel disturbed and also adds to downtime. Operators have to be patient and continue to lead the liners in a straight position to allow proper feeding of the filler metal.

Conclude
When electrically charged wire is feeded to the welding arc MIG welding. MIG welding is generally preferred because it leads to very easy to do. As a matter of fact, it is said that even a robot can be used to obtain mechanical work done. MIG welders are able to work with nearly all the metal kids, even though aluminum and mild steel is the most popular.

Gas Welding Equipment For Quality

Gas welding is a type of development that uses feed the fire that is fueled by gas under pressure. Over different types of spent fuel gas used depends on the job work, accessibility, and price. Gas welding has been aggressively used from many decades, and even though it has been replaced primarily by welding work curve for many industrial jobs, are still respected for the quality and engineering.

Centered on the gas appliances that produce flare welding torch. Skilled welder can adjust the quantity of gas used by the live set on fire and the oxygen is used to supply combustion. With cunning and the ratio of oxygen gas, the welder can produce different flames with different characteristics, depending on the welded material. These welders use a filler rod is covered by the instability of adding a substance to weld and to replace the air from the welding site. Similar to all the welding, the welder must wear protective clothing, along with welding mask, gloves and other accessories to wear.

Earlier than the acetylene can be successfully created and controlled, coal gas and hydrogen is consumed for welding. Today, gas welding is run by propane, gasoline, and hydrogen. Oxy-acetylene gas is the incorporation of the most frequently used by the process of welding equipment. Oxy-acetylene gas welding combines oxygen and acetylene gas to make fire. Acetylene blessed with a flare hottest of all fuel welding, and consequently can be used to weld or cut the material substantially. However, acetylene is pricier than the amount of fuel gas welding.

This process uses bar to start a substance into the welding field. Bars for welding materials covered by the instability that evaporates when heat is given. Actually, the flux of evaporated air relocates from the site so that the welding oxide is not integrated in the welding procedure. Welding bars can be obtained in various substance to go with the substance of the welded workpiece.

Electricity is not required to carry out the gas, so the system can be diverted and used in remote places with no power source. However, the use of gas for welding category flammable and they should be stored and handled properly. Gas welding equipment does not generate as much heat as small as limited to the welding area of ​​the curve, and the benefits of welds made with welding arc welding has resulted in attenuation as the primary process. However, welding is it still remained an important part of the production house.

Tungsten inert gas welding is a welding procedure curves, the heat consumed electricity to melt the metal curve of the number of jobs to produce connected. Unlike metal inert gas welding, tungsten inert gas welding using a tungsten electrode which does not melt and supplies for welding materials.

Interpreter tool includes TIG welding from TIG welding machine, protecting gas, usually argon; stuffing substances and protect the mechanism.

Analysts pointed out welding equipment with gas appliances so whether you need a gas welding equipment or welding equipment you can find the service reliable and consistent welding in NSW, Australia. Terry Burch is the Equipment Industry Analyst in Sydney Australia.

How to Repair Without Welding Cast Iron

Cast iron used in many household and industrial structures. Cast iron is brittle by nature and can be prone to cracks and breaks. Large changes in temperature, thermal gradients and physical shocks such as drops can cause cracks. Cast iron can be repaired using welding techniques, but this is difficult and can cause further damage. Speaker, a technique that uses less heat than welding, often used to repair cracks in cast iron pieces.

Instructions
Choose a filler rod. A filler rod is selected based on the application of the cast iron. Filler rods used for brazing cast iron is often made of nickel or brass. Some assemblers use a filler rod containing flux, while others prefer to use a separate flux during the brazing process.

Prepare the surface cracks. Cracks in the cast iron should be cleaned and prepared before brazing to eliminate impurities and oxide surfaces. Cracks should be ground using a grinder to form a U-shaped cross section. This allows the brazing material to completely flow into the gap and avoid stress concentration.

After grinding, brush the ground using a stainless steel brush. This step will remove any remaining particles from the grinding process.

Heat a cast iron parts. If a brazing torch is used in the cold, cracking and warping further can happen, so that the heat source such as a gas grill, stove or oven weeds can be used to slowly heat the cast iron.

Place a piece of cast iron to the surface of the work and reinforce if necessary. Some parts may require greater heating during brazing process, especially if large cracks and brazing process will take some time. Use an external heater to maintain the temperature of the piece.

Use a brazing torch to heat the surface of the cracks until they turn bright red. Touch the filler rod into the crack surface: the surface temperature must be hot enough to cause the filler rod material to flow into the gap. Use the torch to maintain the local temperature while walking down the crack.

Put the sand into the container repaired and completely covered with sand section. After brazing, the repaired cast iron should be cooled very slowly. If the part is left in the cold, can be cracked. Let the inside of the sand for at least one day, longer if a large part.

How To Weld Cast Iron With Wire Welder

Welding on cast iron is a little different from the weld metal on the other. Because the chemical makeup, cast iron is prone to cracking when heat is applied. Metals such as wrought iron or mild steel can be welded with only minimal preparation. However, cast iron welding requires a material that has become hot before the bow struck, and also require a slower cooling time. If done properly, cast iron can be repaired very successfully.

Instructions

Heat a cast iron evenly with a torch. Because of its nature, cast iron will crack when welded as cold. It requires pre-heating the material to avoid damage. Apply using a torch to heat the entire surface of cast iron, including parts to be welded. By bringing the temperature of cast iron that slowly before welding on it, we can ensure that the heat resulting from the arc does not damage the metal itself. If the object is very large cast iron, heat the surrounding area as the area to be welded as possible. If small pieces, simply reheat the whole thing.

Welding cast iron is very slow, stopping every 1 to 2 inches so that the iron to cool a little in between welds. If you try to weld the whole area in one shot, iron is likely to crack due to extreme heat stress produces. If you are using flux cored wire, use a wire brush and scrape the flux off the weld every time you pause to make sure that gets arc welder, good clean when you resume welding.

Cast iron cools down very slowly after welding. If cast iron is allowed to cool too quickly, cracks are inevitable. If an item is welded rather small, you might consider wrapping it in a thermal blanket or even buried in the sand to prevent rapid cooling. If a large item, hit it with a torch every thirty seconds or so for a short time, which will bring the temperature down gradually.

The Steps Welding Cast Iron

Cast iron is difficult, but not impossible, to weld. In most cases, welding on cast iron involves the repair of castings, not joining casting to other members. Improvements can be made at the foundry where the castings are produced, or can be made to correct errors discovered after the casting of this machine. Mis-cast iron parts may require welding machine improvements, such as when a hole is drilled in the wrong location. Often times, the cast iron damage repaired by welding cast iron parts Fractures are not uncommon, given the fragile nature of most cast iron.

Although there are various types of cast iron, the most common is gray cast iron, and guidelines are addressed to the type of material.

A few facts about cast iron help in understanding the welding challenges. Cast iron typically has a carbon content of 2% - 4%, roughly 10 times the steel. High carbon content causes the carbon to form graphite flakes. This graphite gives gray cast iron characteristic appearance when fractured.

When the castings are made, molten iron is poured into molds and allowed to cool slowly. When this high carbon material was allowed to cool slowly, crack free castings can be made. Considering this is helpful when welding cast iron: during and after welding, casting either be allowed to cool slowly, or should be kept cool enough that the cooling rate is not important.

Critical temperature in most cast iron is around 1450 degrees F. When the temperature conditions, which can cause cracks occur. While casting the arc will heat to temperatures above this level, it is important that the casting is held at this temperature for long periods of time.

Electrode Selection
If the part is to be machined after welding, a nickel-type electrode will be required. Use Lincoln Softweld 99Ni stick electrode to pass, high dilution welds. Softweld 55 Ni is preferred for multiple pass welds. Sometimes, through the roots put in by Softweld 99 Ni, followed by passing the contents of the Softweld 55 Ni. For welds where the machine is not required, and where welding is expected to rust like cast iron, Lincoln Ferroweld ® stick electrode can be used.

For the Heat, or Heat
In general, it is preferred to weld cast iron with preheat - and lots of it. However, another way to successfully weld cast iron is to keep it cool - not cold, but cold. Below, both methods will be described. However, once you choose a method, stick with it. Keep it hot, or cool, but do not change horses in midstream.

Welding Techniques with Preheat
Preheating the cast iron part before welding will slow the rate of cooling of the weld, and the area around the weld. It is always preferable to heat the entire casting, if possible. Typical heating temperature of 500-1200 degrees F. Do not heat over 1400 degrees F since that will put the material into a critical temperature range. Heat the part slowly and evenly.

Weld using a low current, to minimize the mixture, and residual stress. In some cases, it may be necessary to restrict the welds to small segments about 1-inch length to prevent the build up of residual stresses which can cause cracks. Weld bead peening can help in this regard as well.

After welding, allow the part to cool slowly. Wrapping the casting in an insulating blanket, or buried in dry sand, will help slow the cooling rate, and reduce the tendency to crack.

Welding Techniques without Preheat
The size of the casting, or other circumstances, may require that repairs be done without preheating. When this happens, the need to stay cool, but not cold.

Increase the casting temperature to 100 degrees F is helpful. If the part is on the machine, it is possible to run it for a few minutes to get this temperature. Do not heat the casting so hot that you can not put his bare hands on it.

Make it short, about 1 long welds. Peening after welding is important with this technique. Let the cold welding and casting. Do not accelerate the rate of cooling with water or compressed air. It is possible to weld in other areas of the casting while the previous weld cools. All craters shall be filled. Whenever possible, the beads should be stored in the same direction, and preferably the end of the bead is lined up parallel to each other.

Sealing Cracks
Due to the nature of cast iron, tiny cracks tend to appear next to the weld even when good procedures are followed. If the casting must be watertight, it can be a problem. However, leaks can usually be removed with some type of sealing compound or they may be rusted shut down shortly after returning to service.

Studding method
One method used to repair major breaks in large castings is to drill and tap holes on the surface has been tilted to receive the repair weld metal. Screw steel studs into the threaded hole, leaving 3/16 "(5 mm) to ¼" (6 mm) above the surface of the stud. Using the methods discussed above, weld studs in place and cover the entire surface of the break with weld deposit. After a good weld deposit is made, both sides of the crack can be welded together.

Troubleshooting of Underwater Welding

Although there are several obstacles that make the industry are reluctant to use this welding technique, in fact there are some business improvements that have been made, both in technique and quality of welding electrodes, that is :

1. Hydrogen cracking and HAZ hardness in the area can be minimized or avoided by the application of multiple temper bead (MTB). The concept of this technique is to control the ratio of heat (heat input) between the layers of the welding bead. Heat control, the size of the weld bead on the first layer should be adjusted so that the minimum penetration into the material could be obtained. Likewise for the second layer and so on. There are three parameters that affect the quality of welding in the application of this MTB, which is the distance between the bead tempering, welding time range, and heat input.
   
2. Buttering technique can also be used primarily for materials with more than 0.4% CE. Electrodes used butter can have the oxidizing agent electrode or electrodes Thermit.
   
3. Usage of the electrode with the oxidizing agent. This agent will absorb hydrogen or oxygen gas is absorbed in the HAZ.
   
4. Use of Thermit electrodes can also be used. Electrodes of this type will produce a high heat and the provision of weld material (weld metal) are slightly thereby reducing the rate of cooling of the welding by the surrounding temperature, causing a kind of post weld heat treatment process.
   
5. Nickel-based electrodes can not withstand the hydrogen to diffuse into HAZ area. Unfortunately the hardness in the HAZ area is still high and the welding quality is only good for up to 10 meters depth.

Little About Welding Process

The development of metal technology provides ease of connection to humanity in the conduct of life. Today, the advancement of science in electronics through That studies look at the characteristics of atoms, have Contributed greatly to the discovery of new materials and also how do the connection. Manufacturing industry can not be separated from the metal connection. The connection is made of metal for Various purposes, Such as to create an item That is not possible with other techniques, facilitate the work, and can Reduced production costs. Switching process is Widely used metal in the manufacturing industry is welding. Metal welding is a fairly precise. Welding does not require a long time, the construction is lightweight, has a pretty good connection strength, and Relatively low cost.

The definition of welding material is a connection Between two or more of the process utilizing the process of diffusion of the material, based on the principles of magnetic bonds Between atoms of the material to be spliced. Welding can be Divided into two types, namely Solid State and Liquid State Welding Welding: Solid State Welding is a welding process in the which objects in the solid state, and usually by using a pressure That Is Often also called Pressure Welding. Solid State Welding process has Several advantages, Such is Able to connect two or more pieces of material That is not the same melting point, the process is rapid, precise, and almost no heat affected areas (heat affected zone / HAZ). However, Solid State Welding also has drawbacks, namely the preparation and the process is complicated connections, so it takes meticulous very high. Included in the Solid State Diffusion Welding Welding of them, Forge Welding, Cold Welding and Friction Welding.

Liquid State Welding is a welding process in a way That would dilute the area until the liquid is spliced ​​together evenly, Provided the material to be jointed should be the same melting point. Grafting material in this way has to be the same material terms, Because to get a perfect connection material temperature should be equal, if not the process of splicing is not going to Happen. Advantages of this welding method is the preparation process and the connection is not complicated, the cost is Relatively inexpensive, easy implementation. The disadvantage is the need of skilled welders, the HAZ the which cause changes in material properties, and there is potential for accident and health impaired welders. Which includes the Liquid State Thermal Welding Welding, Resistance Welding, and Electric Arc Welding.

Very broad application of the welded joints. Welded joints are Widely used in the construction of bridges, buildings, automotive industry, household appliances industry, and even industrial goods with too many plastic materials using the welding process. Variables That Affect the quality of welded joints, Including: materials, welding process, welding methods are used, used welding equipment, skilled welders, welding environment, testing of welding, safety and health.

Basics Metal Arc Welding

SMAW is often referred to as shielded metal arc welding. It is also referred to as Manual Metal Arc (MMA). An electrode coated with flux material used to make the weld in this type of welding. Electric arc is formed by using either alternating or direct current as power. arc is formed between the metal and the electrode for welding. Shielding gas is formed when the flux is coated on the electrode began to disintegrate and produce steam. This protects the gas from air contamination. Here are some basic welder must know when it comes to welding arc;

Direct current electricity flows from negative to positive. Direct current is used to produce a smooth weld. Power pass to and from positive to negative and the sine wave. This results in an irregular part of the current. In turn this resulted in more debris.

Reverse polarity is called a Direct Current Electrode Positive (DCEP). Direct Current Electrode Negative (DCEN) is called straight polarity. Electricity passes with great concentration to the end of the welding rod to provide only one-quarter less capable in the DCEP. This gives a major attack. thick piece of steel can be welded easily with DCEP.

But the moment passed out of the DCEN welding rod. There is one-third of the heat concentrated on the trunk. This ultimately results in less incursive ability. Therefore serve to the best resources for thinner steel.

There are dozens of people who believe that DCEN provide greater penetration of the DCEP. But with experience you should be in favor of your own.

There are a number of defects can lead to SMAW welding. They are slag inclusions, undercut and porosity. They are called defective because they weaken the joints where the welding done. Porosity is holes that appear in the weld. This may be caused by a gas or vapor.

- Slag inclusion occurs, you do not chip off the slag. welder should always get rid of the slag.

- Disability is a major mistake that should not happen when welding.

- It is very dangerous to weld with exposed skin. Radiation of ultraviolet rays can be brutal to your skin. They can blister your corneas. Exposing the skin while welding cause skin cancer. The main reason why the coat of heavy welding by welders are avoided because they are uncomfortable. It's not a good reason when compared with the losses that welding can pose in your body.

- Rain drizzle drops of molten metal which is trapped by the metal all around where you are welding. Drizzle will chip off by itself.

Copper Craft Production Welding Processes

Welding is one integral part of the production process of manufacturing copper craft. Other manufacturing processes that have been known among other processes putty (Hammered metal), formation (metal forming), machining (machining), and Finishing Color (Finishing color). Products with complex shapes and large size can be made by molding techniques. Products such as pipes, plates and sheets, steel-steel construction is made with the process of formation. Products with a strict and meticulous dimensions can be created by machining. What about the welding process? The welding process which in principle is to connect two or more components, more precisely directed to assemble (assembly) number into a form of machine components. Assembled components may be derived from the product of casting, forming or machining, both from the same metal or different.

Welding (Welding) is one of the Copper metal splicing techniques by partially melt the parent metal and filler metal with or without pressure and with or without additional metal and produces a continuous connection. From the definition there are four key words to clarify the definition of the welding is melt some of Copper, Copper fillers, pressure and continuous connection. From the definition above, the welding process scheme can be made as follows:

Another way of splicing has been known for a long time is in addition to splicing by welding brazing and soldering. The difference with welding brazing and soldering was not to melt the parent metal Copper metal just filler only. While the difference between brazing and soldering is located at the melting point metal filler. Melting point of the brazing filler metals ranging from 450C - 900C. As for the soldering, melting point metal filler is less than 450C.

From the chart above, it can be seen that the welding process can be divided into 3 main sections, namely melting welding (fusion welding), welding does not melt (solid state welding) and soldering / brazing. Thus, in carrying out the welding required to melt the metal and the tool or appliance for heating and emphasize both the metal (Copper-Brass) to be connected. Defrost and heating equipment or metal (Copper-Brass) can be based on the use of electrical energy, gas energy or mechanical energy.

Oxy acetylene welding process

Welding with gas made by burning fuel gas mixed with oxygen (O2), giving rise to a high temperature flame (3000o) were Able to melt the parent metal and filler metal. Type of fuel used acetylene gas, propane or hydrogen, so the way this welding oxy-acetylene welding is called or known by the name of the carbide weld. Acetylene flame is obtained from burning a mixture of oxygen and acetylene gas used to heat the metal until it Reaches the melting point of the parent metal. Welding can be performed with or without filler metal. Oxygen is obtained from electrolysis of water or liquefaction process. Oxygen is commercially Generally come from the air liquefaction process in the which oxygen is separated from the nitrogen. Oxygen is stored in steel cylinders at a pressure of 14 MPa. Acetylene gas (C2H2) is produced from the reaction of calcium carbide with water. Rising gas bubbles and sediment That Occurs is calcium oxide. Reactions occur in acetylene cylinder That is:

CaC2 + 2H2O ® Ca (OH) 2 + C2H2

calcium carbide acetylene gas Cretaceous shallow water

When the count was approximately 1 kg CaC2 Produce 300 liters of acetylene. The nature of acetylene (C2H2) the which is a fuel gas is colorless, non-toxic, odorless, lighter than water, growing niche to separate Themselves when there is an increase of pressure and in temperature (above 1.5 bar and 350 ° C), soluble in a porous mass (acetone).

Calcium carbide is a hard, like stone, gray and formed as a result of Reaction Between Calcium and coal in electric kitchen. The reaction is then crushed, selected and stored in a sealed steel drums. Acetylene gas can be obtained from the acetylene generator acetylene gas produced by mixing carbide with water or can now be purchased in the gas tubes ready for use. To be safe acetylene gas pressure in the tube should not exceed 100 kPa, and kept mixed with acetone. Acetylene tube filled with a porous filler material is saturated with acetone, then filled with acetylene gas. Tubes of this type can accommodate acetylene gas pressurized to 1.7 MPa.

Principle of welding is not too complicated. Simply by adjusting the amount of acetylene gas and oxygen, then ends with a flame near the flame Brought Will Arise. But the amount of acetylene gas and oxygen should be arranged so as to turn the pressure bit by bit. Acetylene gas when it is turned on the flame of the flame used to remove soot. If the acetylene gas too little is played, then the weld will not light.

Speed ​​of recall of gas per hour from an acetylene cylinder must not be Greater than 20% (one fifth) of its contents, so That gas can be flowed acetone (acetylene cylinders must always be perpendicular).

Flame combustion in oxy-acetylene welding may change depending on the ratio Between oxygen gas and the gas asetilennya. There are three Kinds of fire in the oxy-acetylene welding as shown in the figure below:

More acetylene flame (flame carburizing)
That if too many comparisons used the acetylene gas in the inner cone and outer cone will Arise a new cone of blue flame. Among the light cone and the outer sheath of the cone will have whitish, Whose length is determined by the amount of excess acetylene. This will cause the liquid metal carburizing. Flash is Widely used in metal welding monel, nickel, Various types of steel and a variety of non-ferrous material surface hardening.

Neutral flame
This Occurs when the flame of oxygen and acetylene ratio of about one. Flame consists of a cone in a shining white and blue cone outer nodes. Required oxygen flame comes from the water. The maximum temperatures as high as 3300 to 3500 ° C is reached at the end of the flame cone.

More oxygen flame (flame oxidation)
When oxygen gas is more than is needed to Produce the neutral flame flame Becomes shorter and the color changed to purple cone. This flame will cause oxidation or decarburization process on the liquid metal. This oxidation is the flame That must be used in fusion welding of brass and bronze, but not recommended for other welding.

Because it is Able to change the composition of the molten metal excess acetylene flame and the flame of oxygen excess can not be used to weld steel. At the end of the temperature of the cone in approximately 3000 ° C and in the middle of the cone is approximately 2500 ° C.

Resistance Welding Machines Control

Welding is used in many forms. Today, electronics, and other small-size devices are growing in the welding industry, a sector sensitive to the resistance welding process. This is the body, through the melting point of contact and fused weld tannagagi two times when the hot parts, which is a thermal process. This method is similar to other heat sealing, but with some differences. The first of these differences, of course, the size of the components and solder. Microelectrodes micro-resistance welding machines are kept, welder welding process itself, the box containing the control electronics and controls, and the welding head consists of the workpieces in small and put them in contact. Points or contact points rather than themselves as micro-electrodes, 0.010 square centimeter in size, very small. One of the most precise control of electric welders and weld heads, very precise control of the energy of the electrodes would not disrupt the weak.

There are three types of micro-resistance welding electrode welding, dig welding, projection welding straight through. A weld line, welded to each other as objects to be constructed in contrast to the two electrodes, such as electricity, Cut, a heating of the weld. Along the length of a welding electrodes or workpieces, except for the two overlapping sites to be moved to form a continuous series, in fact, a single weld line. A humpback welding projections extending in fact its name from the two surfaces. If this method is a thin piece of a larger piece of welding, thermal balance, the improvement will reduce the amount of energy to dig a welded reasons, a number of uses, so that a plurality of pulse welding with spot welding.


Parallel to the weld gap to the following two types of micro-resistance welding mentioned in the preface. Both the type of welding electrodes, making approached in the same direction. With an insulating layer on the opposite side of the pieces of this technique is especially useful when welded. Currently, there are two things in a series configuration of the electrode assembly and the other electrode, an electrode and allows the flow. Welding step, the contact electrode material and the flow passes through the interface that all objects.

The first step is to perform micro-resistance welding, the copper electrode on the other two parts over the place. Next, the welding head, welding, narrow, two pieces brought to a point near the bottom of the upper electrode. Transfer the pieces to the point of intersection of the two current electrodes are pressed together. There is a connection between the two electrodes to heat the material quickly, but both were to dissolve. Power when weld between the two parties to form, cooling the molten zone and solidifies.

Micro resistance welding systems for automotive, aerospace, medical and electronics manufacturing, including the majority of areas, including in many applications. Micro resistance welding of thin wires soldered to the rest of widespread PCB pads are used for the electronic industry. Some of the naming of this type of welding, sensors, lights, batteries, used in the manufacture of solar panels and smoke detectors. Automobile sector, micro-resistance welding of light, air bag systems, electronic sensors and controls used.

In short, the most popular form of micro-resistance welding connection hardware. It would be cheaper for a clean, safe and fast. The usefulness of micro-resistance welding to the development of the industry.
