  2. Hyperbaric welding - Wikipedia

    en.wikipedia.org/wiki/Hyperbaric_welding

    Underwater welding Underwater welding habitat for dry 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.

  3. Welding power supply - Wikipedia

    en.wikipedia.org/wiki/Welding_power_supply

    A welding power supply is a device that provides or modulates an electric current to perform arc welding. [1] There are multiple arc welding processes ranging from Shielded Metal Arc Welding (SMAW) to inert shielding gas like Gas metal arc welding (GMAW) or Gas tungsten arc welding (GTAW).

  4. Arc welding - Wikipedia

    en.wikipedia.org/wiki/Arc_welding

    Arc welding power supplies can deliver either direct (DC) or alternating (AC) current to the work, while consumable or non-consumable electrodes are used. The welding area is usually protected by some type of shielding gas (e.g. an inert gas), vapor, or slag. Arc welding processes may be manual, semi-automatic, or fully automated.

  5. Power inverter - Wikipedia

    en.wikipedia.org/wiki/Power_inverter

    A power inverter, inverter, or invertor is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC). [1] The resulting AC frequency obtained depends on the particular device employed. Inverters do the opposite of rectifiers which were originally large electromechanical devices converting AC to DC.

  8. 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 ...
