  2. Oxy-fuel welding and cutting - Wikipedia

    en.wikipedia.org/wiki/Oxy-fuel_welding_and_cutting

    A cutting torch head is used to cut materials. It is similar to a welding torch, but can be identified by the oxygen blast trigger or lever. When cutting, the metal is first heated by the flame until it is cherry red. Once this temperature is attained, oxygen is supplied to the heated parts by pressing the oxygen-blast trigger.

  3. Flashback arrestor - Wikipedia

    en.wikipedia.org/wiki/Flashback_arrestor

    This type is typically found in cutting and welding applications all over the world. They work equally effectively in all orientations, and need very little maintenance. The simplest flashback arrestor consists of a metallic tube filled with iron wool, which cools the flame below the ignition temperature.

  4. Thermal lance - Wikipedia

    en.wikipedia.org/wiki/Thermal_lance

    A thermal lance, thermic lance, oxygen lance, or burning bar is a tool that heats and melts steel in the presence of pressurized oxygen to create very high temperatures for cutting. It consists of a long steel tube packed with alloy steel rods, which serve as fuel; these are sometimes mixed with aluminum rods to increase the heat output.

  5. Plasma cutting - Wikipedia

    en.wikipedia.org/wiki/Plasma_cutting

    Plasma cutting is an effective way of cutting thin and thick materials alike. Hand-held torches can usually cut up to 38 mm (1.5 in) thick steel plate, and stronger computer-controlled torches can cut steel up to 150 mm (6 in) thick.

  6. Plasma torch - Wikipedia

    en.wikipedia.org/wiki/Plasma_torch

    A plasma torch cutter. A plasma torch (also known as a plasma arc, plasma gun, plasma cutter, or plasmatron) is a device for generating a directed flow of plasma. [1] [2] [3] The plasma jet can be used for applications including plasma cutting, plasma arc welding, plasma spraying, and plasma gasification for waste disposal. [4]

  7. 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 ...

  8. Japanese aircraft carrier Chiyoda - Wikipedia

    en.wikipedia.org/wiki/Japanese_aircraft_carrier...

    With two additional diesel engines operating Chiyoda could attain 28.5 knots (52.8 km/h; 32.8 mph). With the loss of four large aircraft carriers at the Battle of Midway, the Imperial Japanese Navy rushed a project to convert the Chitose-class into light aircraft carriers as partial compensation. A wooden 180 by 23 metres (591 ft × 75 ft ...

  9. Water jet cutter - Wikipedia

    en.wikipedia.org/wiki/Water_jet_cutter

    The term abrasive jet refers specifically to the use of a mixture of water and an abrasive to cut hard materials such as metal, stone or glass, while the terms pure waterjet and water-only cutting refer to waterjet cutting without the use of added abrasives, often used for softer materials such as wood or rubber.
