  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. Arc welding - Wikipedia

    en.wikipedia.org/wiki/Arc_welding

    Gas tungsten arc welding (GTAW), or tungsten/inert-gas (TIG) welding, is a manual welding process that uses a non-consumable electrode made of tungsten, an inert or semi-inert gas mixture, and a separate filler material. Especially useful for welding thin materials, this method is characterized by a stable arc and high quality welds, but it ...
