how dangerous is underwater welding

Underwater welding is extremely dangerous due to a combination of electrical hazards and challenging underwater conditions. Major risks include electrical shock from high-voltage equipment in a conductive environment, drowning caused by equipment failure or human error, decompression sickness from rapid ascents, hypothermia from cold water exposure, and explosions or burns due to flammable gases underwater. Additional challenges arise from poor visibility, strong currents, and high water pressure, all complicating the work environment. Despite rigorous training, specialized equipment, and strict safety protocols, the job remains one of the most hazardous professions, with a high potential for fatal accidents and serious injuries.
