because when you strike an arc underwater, the light attracts sharks, and then they eat you.
Underwater welding has an average mortality rate of 13 - 17 percent. The leading cause of death is electric shock from improperly insulated equipment.

One type of welding is tube welding. Another type if mig welding.
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.
There's only been one incident involving an actual death during the process of underwater welding, which happened in 1943 when a student was wet welding. The potential danger from electric current during underwater welding is extremely low because the welder-diver is grounded. It's also direct current (DC), not alternating current (AC), so it's focused at the weld site. Other dangers to underwater welders (commercial divers) are more prevalent, including decompression sickness and drowning. I outline these dangers in my article: waterwelders.com/zap-bang-pop-hazards-safety-measures-of-underwater-welding/
