Here are some more information for Tig Mma:
Underwater welding techniques are most commonly used in executing marine engineering projects such as installation of oil and gas rigs. Underwater welding is mostly related to welding work pieces made from different types of metals such as steel, aluminum, copper, and others.
Underwater welding can be classified according to the type of equipment used and the type of processes followed. The most common underwater welding process is known as manual metal arc welding (MMA) which has the advantage of being relatively insensitive to depth. This makes it the most suited technique for undertaking deep-water repair activities.
Cofferdam welding involves the use of a rigid structure to house the welders, which is sealed against the side of the structure to be welded. Another type of underwater welding technique is commonly known as Hyperbaric welding in which an enclosure is sealed around the structure to be welded, and is filled with a gas (commonly helium containing 0.5 bar of oxygen) at the prevailing pressure. This welding technique is often combined with MMA (SMA), TIG (GTA), or FCAW for effecting high integrity welds, particularly for deep-water welds, including tie-ins in pipelines and risers in the oil and gas industries.
Underwater welding techniques are used for welding steel pipelines, other offshore structures, submerged parts of large ships, and underwater structures supporting a harbor. Welding in depths of 500 to 1000 meters generates high weld metal diffusible hydrogen, which can increase the risk of hydrogen-assisted cracking. This can be prevented with the use of electrode coating formulations and improved power source technology.
Underwater welding techniques can be dangerous if proper procedures and equipment is not used. An underwater welder faces the potential risk from electric shocks and from nitrogen introduced into the bloodstream during exposure to air at increased pressure. Underwater welding safety measures include emergency air or gas supply, stand-by divers, and decompression chambers to avoid decompression sickness following rapid surfacing after saturation diving.

how to choose MMA welding
MMA welding is used by lots of comany,and its process is simple for people who learn the welding techniques.
of course?just as the saying goes: "Every coin has its two sides",the MMA welding has its advantages and drawbacks with the applications.
ok,let's look at the advantages first.
1.process
MMA welding process cna find innumerable applications throught the availability of a wide variety of electrodes.
2.Convenience
the welding can be operated by welder with hightest weld quality,its operator are very easy in location.
3.range
A big range of metals and their alloys can be welded.
4.cost
the MMA welding machine equipment is low,and the people can pay for it.
5.Joints
the joints can weld easily by MMA welding machine,but other welding machines are difficult to be welding by welding machine in any position.
the Limitations of MMA welding 1.length MMA welding machine limite the length of each electrode,so this is a disadvantage for welding machine.
2.long joints you may have a little bit confusing about joints,for i say the joints is its advantage,but now the joints is its limitation.now,i say the reasons. in welding long joints,the welding is to be progressed,but in slag inclusion or insufficient penetration,it may occur at the place where welding is restarted with new electrode,so the long joints is limition for MMA welding.
3.speed
the MMA welding is slower than MIG welding,for MMA welding uses stick electrodes.
4.slag
Because of fumes and particles pf slag,the chances of slag entrapment and other related defects are more as compared to MIG or TIG welding,the arc and metal transfer is not very clear and thus welding control in this process is a bit difficult as compared to MIG welding.
we can know the coin has its two sides ,but the MMA welding advantage is major.the advantages of MMA welding for welder outweigh its disadvantages. MMA Applications is revolutionizing the way people learn Mixed Martial Arts around the world. MMA Applications aims to improve your skills one app at a time,almost all the commonly employed metals and their alloys can be welded by this process.we can find the applications in ship building ,pipes and penstock joining,air receiver,tank and so on.
