Underwater Welder Job Description

underwater welder

Underwater Welder employs various common arc welding processes to cut and weld in an aquatic environment. They use their diving and welding skills to lay down strong welds keeping in mind the procedures and protocol prescribed. They often work underwater in tight spaces and surroundings. Normally, they perform wet welding in open waters (up to limited depths) and use hyperbaric chambers and cofferdams for dry welding. Due to safety reasons, Underwater Welders use direct current (DC) settings rather than alternating current (AC) for working.

They use many welding types both for wet and dry underwater welding. They are SMAW, FCAW, friction welding, habitat welding, pressure welding, dry spot welding, dry chamber welding, GTAW, GMAW, and plasma arc welding.
