Hyperbaric welding is the process of extreme welding at elevated pressures, normally underwater. [ 1 ] [ 2 ] 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.
This is a list of welding processes, separated into their respective categories. The associated N reference numbers (second column) are specified in ISO 4063 (in the European Union published as EN ISO 4063 ). [ 1 ]
Most underwater welding is direct current wet stick welding, and most underwater metal cutting is immersed oxygen-arc and shielded metal-arc cutting, though other technologies are available and sometimes used. These processes are mostly applied to steel structures as that is the most common arc-weldable material used in the underwater ...

A positive pressure enclosure, also known as a welding habitat or hot work habitat, is a chamber used to provide a safe working environment for performing hot work in the presence of explosive gases or vapors. They are commonly used in welding environments and are associated with the offshore oil industry. [1]

The therapy involves breathing pure oxygen in a chamber with above-normal air pressure. Some treatments are endorsed by medical experts, but not all.
Other arc welding processes include atomic hydrogen welding, electroslag welding (ESW), electrogas welding, and stud arc welding. [46] ESW is a highly productive, single-pass welding process for thicker materials between 1 inch (25 mm) and 12 inches (300 mm) in a vertical or close to vertical position.
