How is it possible to weld under water???
Yes. Electricity is used, not a flame. Underwater welding (underwater arc welding) is a process used to join to pieces of metal together with a type of filler metal. Under water welding is very similar to topside welding with the exception of a few safety precautions that are instrumental for a safe work environment. In order to become a underwater welder you need to attend a commercial diving school (underwater welding tech. school). Normally, these schools last 2 to 6 months long however there is one in Santa Barbra that has a 2 year program. The 2 to 6 month programs in general require at least 25 hours a week . In dry underwater welding, the weld is performed at the prevailing pressure in a chamber filled with a gas mixture sealed around the structure being welded. For this process, gas tungsten arc welding is often used, and the resulting welds are of high integrity. For the structures being welded by wet underwater welding, inspection following welding may be more difficult than
