Advances in Automatic Hot Wire GTAW (TIG) Welding | …
Hot wire GTAW welding is a further development of the Gas Tungsten Arc Welding or Tungsten Inert Gas process. GTAW was invented by Russell Meredith working at Northrop Aircraft Company in 1939-1941. The GTAW process was initially called "Heliarc" as it used an electric arc to melt the base material and helium to shield the molten puddle.
Resistance Welding Overview
Resistance welding is a welding technology widely used in manufacturing industry for joining metal sheets and components. The weld is made by conducting a strong current through the metal coination to heat up and finally melt the metals at localized point(s

Gas metal arc welding
In general, processes such as shielded metal arc welding and flux cored arc welding are preferred for welding outdoors, making the use of GMAW in the construction industry rather limited. Furthermore, the use of a shielding gas makes GMAW an unpopular underwater welding process, and for the same reason it is rarely used in space appliions.
