Underwater welding uses a special flux around the welding rod which produces gasses which form a bubble around the end of the rod ,excluding the water. It is difficult and never as strong, lacking penetration. It is only used when absolutly necessary.

TW = thermite welding, a welding process that requires no external source of heat or current.
Underwater welding is the process of using an energy source that produces lots of heat to melt together large pieces of metal while diving underwater. There are many great underwater welding schools that can provide this training. You can find these listed from the American Welding Society.
In dry welding for underwater welding, a hyperbaric chamber is used to create a dry, pressurized environment for the welder to work in. The chamber is sealed to prevent water from entering and is pressurized to balance the external water pressure. The welder enters the chamber through an airlock system and performs welding tasks with the help of specialized equipment and gas supply systems.
