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. It is predominantly referred to as "hyperbaric welding" when used in a dry ...

Diver-welders and welding operators for hyperbaric dry welding ISO 17635: Non-destructive testing of welds. General rules for metallic materials ISO 17660-1: Welding - Welding of reinforcing steel - Part 1: Load-bearing welded joints ...
Oxygen arc cutting and arc welding underwater requires greater skill and stamina than working in a dry and stable environment. The underwater environment imposes several limitations and restrictions on both the equipment and the operator, and the restriction of short bottom times at greater depths for surface-oriented divers makes efficient working important to getting the job done in a ...
A modern underwater welding. Khrenov dedicated his entire career to the development of welding techniques and equipment. He invented methods of electric welding and cutting metals under water, designed power sources for arc and spot welding, ceramic fluxes, electrode coatings, methods of cold pressure welding, diffusion welding, plasma cutting and many others.

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]
All of these types of shocks come from the welding electrode terminal. Often these shocks are minor and are misdiagnosed as being an issue with a power tool or the power supply to the welder's area. However, the more likely cause is from stray welding current which occurs when current from the welding cables leaks into the welder's work area.
Hyperbaric treatment schedules – Planned hyperbaric exposure using a specified breathing gas as medical treatment; Oxygen window – Physiological effect of oxygen metabolism on the total dissolved gas concentration in venous blood; Physiology of decompression – The physiological basis for decompression theory and practice; Decompression ...
Medical students demonstrate the use of a portable hyperbaric bag. A portable hyperbaric bag, of which one brand is the Gamow (pronounced) bag, is an inflatable pressure bag large enough to accommodate a person. The patient can be placed inside the bag, which is then sealed and inflated with a foot pump.
