  2. Hyperbaric welding - Wikipedia

    en.wikipedia.org/wiki/Hyperbaric_welding

    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 ...

  3. Decompression sickness - Wikipedia

    en.wikipedia.org/wiki/Decompression_sickness

    Recompression and hyperbaric oxygen administered in a recompression chamber is recognised as the definitive treatment for DCI, but when there is no readily available access to a suitable hyperbaric chamber, and if symptoms are significant or progressing, in-water recompression (IWR) with oxygen is a medically recognised option where a group of ...

  4. Underwater cutting and welding - Wikipedia

    en.wikipedia.org/wiki/Underwater_cutting_and_welding

    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 ...

    lite.aol.com/tech/story/0022/20240905/9225973.htm

    The ability to perform complex welding tasks in challenging underwater environments has made this technology indispensable to industries operating offshore or near large bodies of water. Hyperbaric welding encompasses both dry (performed inside a specially created underwater chamber) and wet welding (performed directly in the water).

  6. History of decompression research and development - Wikipedia

    en.wikipedia.org/wiki/History_of_decompression...

    This painting, An Experiment on a Bird in the Air Pump by Joseph Wright of Derby, 1768, depicts an experiment originally performed by Robert Boyle in 1660. Decompression in the context of diving derives from the reduction in ambient pressure experienced by the diver during the ascent at the end of a dive or hyperbaric exposure and refers to both the reduction in pressure and the process of ...

  9. Positive pressure enclosure - Wikipedia

    en.wikipedia.org/wiki/Positive_pressure_enclosure

    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]
