Exploring the deep sea is like exploring another world. Construction projects like bridges and oil platforms stretch into these underwater realms, needing skilled workers to build and keep them in shape. On land, welding and construction are familiar tasks, but underwater, it's a whole new game. Welcome to the world of commercial diving, where underwater welding takes centre stage.

Underwater welding is often called one of the riskiest jobs out there, facing challenges from the environment, tools, and the welding process itself.

Many people haven't heard of underwater welding or think it's too risky. But it's surprising to learn that it's not only possible but also essential for tasks like emergency ship repairs, installing offshore structures, and building harbour facilities. This special feature dives into everything about underwater welding: the basics, different types, risks, and methods used.

The Fundamentals of Underwater Welding

Underwater welding, credited to the Russian metallurgist Konstantin Krenov in the early 1930s, remains a vital technique for maintaining and repairing submerged marine structures worldwide. Also known as hyperbaric welding, this method is conducted while the welder is submerged, typically at varying barometric pressures.

Contrary to common belief, underwater welding isn't vastly different from its land-based counterpart. Both employ similar fundamental techniques and tools. While some may imagine underwater welding to be performed directly in the water, making the welder wet, it can actually occur either underwater (referred to as wet welding) or within a dry, pressurised enclosure (known as dry welding).
