2. Gas tungsten arc welding - Wikipedia

   en.wikipedia.org/wiki/Gas_tungsten_arc_welding

   Gas tungsten arc welding (GTAW, also known as tungsten inert gas welding or TIG, and heliarc welding when helium is used) is an arc welding process that uses a non-consumable tungsten electrode to produce the weld. The weld area and electrode are protected from oxidation or other atmospheric contamination by an inert shielding gas (argon or ...

4. Arc welding - Wikipedia

   en.wikipedia.org/wiki/Arc_welding

   Arc welding. Arc welding is a welding process that is used to join metal to metal by using electricity to create enough heat to melt metal, and the melted metals, when cool, result in a binding of the metals. It is a type of welding that uses a welding power supply to create an electric arc between a metal stick ("electrode") and the base ...

   The Welding Institute is a professional engineering institution established in 1923 to support the development of engineering professionals in the fields of welding, joining and allied technologies. The Welding Institute is a membership organisation as well as being a licensed member of the Engineering Council, which allows them to assess and ...

6. Plasma arc welding - Wikipedia

   en.wikipedia.org/wiki/Plasma_arc_welding

   Plasma arc welding is an advanced form of tungsten inert gas (TIG) welding. In the case of TIG, it is an open arc shielded by argon or helium, whereas plasma uses a special torch where the nozzle is used to constrict the arc while the shielding gas is separately supplied by the torch. The arc is constricted with the help of a water-cooled small ...
