Underwater wet welding techniques

Although the underwater wet welding techniques (in this case in question is wet welding) has been known since 1930, but in reality not many interested parties to apply as an Appropriate solution. There are Several benefits of this welding technique, Including the Relatively cheaper cost and preparation required is much shorter than with other techniques, but there are other Things That Must be Considered before Applying. This article will discuss about its application in the repair of offshore structures with a focus on the constraints and challenges. During the period of operation, offshore structures will require some intervention under the water for maintenance, repairs or changes Such as:

Strengthening structures for recertification WHO have exhausted its design life
Improvement due to design errors
Repairs due to damage Caused by:
Error during installation
Incidents, eg ship-groundings, storms, falling objects from the upper deck, etc.
cracks at the junction due to environmental conditions (waves, wind)
The Addition of the structure Because of changes in operations (riser clamp installation, caisson, etc..)
Anode installation

As Mentioned above That have not been many interested parties to implement these underwater welding techniques. It is evident That there are only 50 events under the water for repair welding of offshore structures were published during That the last 40 years, it's also a bit of information That is technique. The industry is still interested in using hyperbaric welding or mounting clamp even though it took preparation is more complicated and more expensive costs. Below are described some of the obstacles still exist That Make That the industry is still reluctant to use this technique, as well as some challenges if we want to use it. Interventions for the above, there are Several commonly used techniques Such as

Grinding out cracks

• Clamps
• Grout filling
• Hyperbaric welding
• Underwater welding

Constraints
The reluctance of the industry to use underwater welding technique is understandable considering the Following things:

Class, either DNV or have not received LR technique for permanent repairs. There are weld the which almost always accompanies defects (porosity, lack offusion, cracking) these burdensome welding technique for permanent improvement purposes. element is to repair the 'less important', classs can accept it as a conditional permanent Could be Considered a permanent home in the next inspection found no significant reduction of the quality of welding TSB.

AWS D3.6 refers to: 1999 'Specification for underwater welding', the best results can be obtained from this technique is a new Class B. Such results can only be acceptable if the purpose of welding That is only for the applications are less Important / critical applications where lower ductility, porosity is more, the discontinuities are Relatively more acceptable. If welding is used usually only applied for purposes That are 'fit for purpose' only.

The high risk of hydrogen cracking in the HAZ area, ESPECIALLY for That material has higher levels of carbon equivalent of 0.4%. Especially in the North Sea, offshore structures used to use this material.

Of experience in the industry, welding technique is only performed up into no more than 30 m.

Shielded metal arc process performance (SMA) of ferritic electrodes deteriorate with advancing into.

Commercial producers also limit the use of electrodes to a depth of 100 meters.

The nature of the welding results also deteriorated with Increasing depth, ESPECIALLY for small ductility and toughness.

Due to direct contact with water, the water around the welding area to boil and Becomes ionized hydrogen gas and oxygen. Most of the gas is fused into the HAZ area but most of the others will flow into the water. When the flow is retained, there will be a risk of explosion is usually harmful to divers.

RESOLUTION
Although there are Several obstacles That made the industry reluctant to use this welding technique, there are actually some of the restoration effort has been done That, both in technique and quality of welding electrodes, Such as:


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. To control this heat, 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. That there are three parameters affect the quality of welding in the application of this MTB, namely: the distance Between the temper bead, timescales and heat input welding.

Buttering technique can also be used primarily for materials with more than 0.4% CE. Electrodes butter use oxidizing agent electrode or electrodes have Thermit.

Usage of the electrode with the oxidizing agent, this agent will absorb hydrogen or oxygen gas is absorbed in Haz

Use of Thermit used. Electrode electrodes Could also be producing this type of high heat delivery and welding material (weld metal) are thereby slightly reducing the rate of cooling of the welding by the surrounding temperature, Causing a kind of post weld heat treatment process.

Nickel-based electrodes can not withstand the hydrogen to diffuse into HAZ area. unfortunately only a hardness in the HAZ area is still high and the welding quality is only good for up to 10 meters depth.

WE MUST DO
As Mentioned above, in Addition to lower cost, the most Important thing to Consider in the selection of underwater welding applications is the preparation of the brief. Equipment used for this work is similar to dry welding techniques. there are some Things to think about so That the application of underwater wet welding technique is more acceptable to the industry:

The Things Mentioned above to bridge shortcomings in the new underwater welding job proved to a depth of up to 30 meters. Welding institutions must be proactive to try new techniques for deeper waters.

Welding techniques depend on the ability of divers. That means even if the technique allows, welding can only be done up to a depth of 200 meters. Needs to Consider the use of automatic or mechanical techniques for deeper waters.

Classification of Electric Welding Process

Electric welding with Carbon Electrodes, for example: an electric appliance with a single blast of carbon electrodes with an electric double carbon electrodes. On the electric base with carbon electrodes, the electric arc occurring between the end of the carbon and metal electrodes or between the two ends of the carbon electrodes to heat and melt the metal to be welded. Can be used as an ingredient added to the flux electrode or electrodes are webbed.

1. Electric welding with metal electrodes, for example:
2. Welding with electrodes webbed
3. TIG welding (Tungsten Inert Gas)

4. Submerged electric welding.
5. Welding with electrodes webbed

This electric welding electrode webbed as additives.
Electric arc occurring between the tip electrode and the base material will melt the tip of the electrode and the used base material. Membrane electrode that also burns will melt and produce a gas that protects the tip of the crater welding electrodes, an electric arc to the effects of outside air. Liquid membrane electrode which will freeze the surface of the weld stop up that also serves as a protection against external influences.
Electric arc temperature difference depends on where the measurement point, eg, the electrode tip temperature of 3400 ° C, but the workpiece can reach temperatures of 4000 ° C.

Electric TIG welding
TIG welding (Tungsten Inert Gas = Noble Gas Tungsten) using a tungsten electrode which is not an added ingredient. Electric arc between tungsten electrode tip and the base material is a heat source, for welding. Melting point of tungsten electrode is so high up to 3410 ° C, so that did not participate in the event of melting electric arc.
Electric rod equipped with a ceramic nozzle to protect the throwers protective gas welding area from the outside at the time of welding.
Most of the added material is used without the membrane electrode is moved and brought to the arc between tungsten electrode base material.
Argon used as a protective gas, helium or a mixture of both gases is that of usage depending on the type of metal to be welded.
TIG welding rod is usually cooled with less water circulating.

TIG welding burner consists of:
Submerged electric welding is usually automatic or semi-automatically using the flux powder for the protective effect of outside air. An electric arc between the electrode tip and the base material in the pile so that no ray flux welding out as usual on other electric welding. Welding operator does not need to use a glass eye protection (welding helmets).
At the time of welding, flux powder and frozen and will melt coating welded shut. Most of the flux powder which melts not be used again after cleaning of the slag-slag welding.
Electrode which is a coil-shaped wire vacum membrane (roll) is moved forward by a couple gears are rotated by an electric motor ean be arranged according to the needs of the welding speed.

Electric MIG welding
As with any electrical pedestal pad TIG, MIG power base pad is also heat generated by an electric arc between two electrons and the base material.
Electrode is a wire coil which moves in the form of rollers arranged by the couple gear-driven electric motor. Movement can be adjusted as necessary. The shaft is equipped with a nozzle weld metal to connect the protective gas is supplied from the gas bottle through the gas hose.
CO2 gas is used for welding mild steel and steel. Argon or a mixture of argon and helium for welding aluminum and stainless steel. MIG welding process is semi automatic get or automatic. Semi-automatic welding meant manually, while the automatic welding is carried out entirely automatic.
The electrodes exit through the stalks together with a protective gas.

Electric current
At this current, the electrons move along the conductor in one direction only.
Direction of flow of alternating current is sinusoide wave intersecting the zero on the time interval 1/100 second for a machine with a frequency of 50 hertz (Hz). Each cycle consisted of half-wave wave of positive and negative waves some middle. Alternating current can be converted into direct current by using a flow modifier

Classification Welding & Cutting

Up to this time a lot of classification methods used in the welding field, is due to the agreement in such matters. In the conventional ways of classifying these at this time can be divided into two groups, namely the classification based on the work and the classification based on energy use. The first classification divides molten weld in the welding, welding press, welding and other welding. While the second classification distinguishes the groups such as welding, chemical welding, mechanical welding and so on. If a more detailed classification is held again, then both of the above classifications will be mixed and formed groups are aplenty. Between the two ways of classification mentioned above classification seems to work more widely used because it is the classification described in this chapter are also based on the way to work. This classification is based on the wel ding can be divided into three main classes, namely: Liquid welding, welding and soldering press.Welding welding how in which the liquid is heated to melt the connection with the heat source of an electric arc or gas flame burning sources.

1. Welding welding press is the way in which connections are heated and then pressed up into one.
2. Soldering welding is the way in which the connection was tied up and put together programs so use a metal alloy having a low melting point. In this case the parent is not involved melting metal. Cuts are discussed in this book is how to cut metal that is based on a cut metal melt. Way that is widely used in welding and cutting with oxygen gas by the electric arc cutting. Welding is the most widely used at this time is a liquid with arc welding gas.

How welding press is where the connection is heated and then pressed up into one. Which soldering welding connection is tied to and incorporated programs so using a metal alloy having a low melting point. In this case the parent is not involved melting metal.

Cuts are discussed in this book is how to cut metal that is based on a cut metal melt. Way that is widely used in welding and cutting with oxygen gas by the electric arc cutting. Welding the most used at this time arc welding with gas liquid. Because it both ways, namely electric arc welding and gas welding will be discussed separately. While welding ways that would otherwise be grouped in a single subject. Cutting, because it is a separate issue then the discussion is also carried out separately. Below is the classification of the welding means:

a) Welding of liquid

1. Gas welding
2. Electric welding slag
3. Electric welding gas
4. Thermic welding
5. Electron electric welding
6. Plasma arc welding

5. Press welding
6. Blunt press welding
7. Press the gas welding
8. Wrought welding
9. Friction welding
10. Explosion welding
11. Induction welding
12. Ultrasonic welding

Various types of welding processes

There are various types of welding processes and each has its own advantages and disadvantages, including:

1. Arc welding is a technique that uses the power supply and create an electric arc between the electrode and the base material.
2. Forge welding is a process that joins metals by heating them to high temperatures.
3. Tig tungsten electrode to produce weld and it is another name for gas tungsten arc welding of metals and used for thin sections of stainless steel and non ferrous metals.
4. Mig welding is automated arc welding process for its versatility and speed and the welding of aluminum and non ferrous materials.
5. Spot welding is a process in which metal surfaces are joined with the heat obtained from resistance of current flow.
6. Gas welding is also referred to as oxy-fuel welding and gas used for welding and cutting metals.
7. Stick or shielded metal arc welding is a process that uses manual arc consumable electrode.
8. Arc plasma using a plasma gas and has a narrow penetration with a greater concentration of energy.
