          Hyperbaric welding  is the process of extreme  welding  at elevated  pressures , normally  under water. 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. It is predominantly referred to as "hyperbaric welding" when used in a dry environment, and " underwater welding " when in a wet environment.  . It is predominantly referred to as "hyperbaric welding" when used in a dry environment, and " underwater welding " when in a wet environment. The applications of hyperbaric welding are diverse—it is often used to repair ships , offshore oil platforms , and pipelines. steel  is the most common material welded. Dry welding is used in preference to wet underwater welding when high quality welds are required because of the increased control over conditions which can be ma...
