How does underwater welding work?

Welding and water. Electricity and fluid. Under most circumstances, we see this mixture as a bad idea. When electricity is generated within a fluid, it reacts unpredictably. And unlike insulated solids (think copper wire), there's no specific path generated for the electricity to move through. read more

How does Underwater Welding Work Under the Hood: Equipment, System & Circuit Process Explained. The underwater wet welding cable system and power source are a little different from underwater dry welding (and surface welding). Underwater wet welding insulates its electric cables twice. read more

Certification as a welder is also necessary, as well as knowledge of both dry and wet welding. Underwater welders must have advanced knowledge of commercial diving equipment and wet and dry welding tools and techniques; other important skills include underwater photography, welding inspection, cutting, and fitting. read more

Hyperbaric welding is the process of welding at elevated pressures, normally underwater. Hyperbaric welding can either take place wet in the water itself or dry inside a specially constructed positive pressure enclosure and hence a dry environment. read more
