What are the dangers of underwater welding?
The risk factors of underwater electric welding and cutting are characterized by that arc and gas flame are used in water, which is more dangerous than welding in the atmosphere and general diving operations.
Common accidents in underwater electric welding and cutting operations include electric shock, explosion, burn, burn, drowning, injury, diving disease or suffocation. The causes of the accident are as follows:
(1) There are often ammunition, fuel containers and dangerous chemicals in ships and other objects submerged in the water. If they operate freely without knowing the situation before welding, explosion will occur during welding.
(2) Accidents caused by burning doors and hot metal droplets, burning operators, or burning air supply pipes, diving suits and other diving equipment.
(3) Electric shock caused by insulation damage or misoperation.
(4) There were striking, crushing, crushing and even death accidents caused by the collapse of underwater parts.
(5) The gas supply pipe and diving suit were burned in the water, and drowning accidents were caused by the dangerous electricity of underwater electric welding and sea storm.
