2. Gas tungsten arc welding - Wikipedia

   en.wikipedia.org/wiki/Gas_tungsten_arc_welding

   However, TIG welding is comparatively more complex and difficult to master, and furthermore, it is significantly slower than most other welding techniques. TAG welding (short for "tungsten argon gas welding") [citation needed] was the name given in the early 1970s to the then-novel and revolutionary method of rod welding previously problematic ...

3. Orbital welding - Wikipedia

   en.wikipedia.org/wiki/Orbital_welding

   Orbital welding has almost always exclusively been carried out by the Tungsten Inert Gas (TIG / GTAW) technique using non-consumable electrodes, with additional cold-wire feed where necessary. The easy control of heat input makes TIG-welding the ideal welding method for fully orbital welding of tubes with specialist orbital welding heads, that ...

5. Shielding gas - Wikipedia

   en.wikipedia.org/wiki/Shielding_gas

   Limited to short circuit and globular transfer welding. Common for short-circuit gas metal arc welding of low carbon steel. C-20 (80% argon/20% CO 2) is used for short-circuiting and spray transfer of carbon steel. C-15 (85% argon/15% CO 2) is common in production environment for carbon and low alloy steels.

6. Hyperbaric welding - Wikipedia

   en.wikipedia.org/wiki/Hyperbaric_welding

   Dry hyperbaric welding involves the weld being performed at raised pressure in a chamber filled with a gas mixture sealed around the structure being welded.. Most arc welding processes such as shielded metal arc welding (SMAW), flux-cored arc welding (FCAW), gas tungsten arc welding (GTAW), gas metal arc welding (GMAW), plasma arc welding (PAW) could be operated at hyperbaric pressures, but ...
