Video answer: Why underwater welding is so dangerous & high paying!
Top best answers to the question «Why is underwater welding dangerous»
Since many underwater welders work hundreds of feet beneath the surface, they are subjected to dangerous pressure changes. Decompression illness is caused by a reduction in the ambient pressure surrounding the body. This results in two potential health risks: decompression sickness and arterial gas embolism.

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/
