What is hyperbaric welding?

Hyperbaric welding is a specialized welding process performed at elevated pressures, typically underwater or in a pressurized chamber. It is most commonly used for repairing and constructing underwater pipelines, ships, and offshore structures. There are two main types: wet welding, where the welder works directly in the water, and dry welding, where a pressurized chamber (habitat) is used to keep the work area dry. This technique requires highly skilled welders due to the challenging environment and is critical for maintaining essential underwater infrastructure.
