TIG Welding (With Diagram) | Metallurgy The Argon arc welding is same as TIG welding. TIG welding uses an arc formed between a non-consumable electrode and work metal. The welding of non-ferrous metal and their alloys in manual arc processes use a corrosive flux. But in the gas shielded Tungsten arc process, ferrous and non-ferrous alloys are welded without the use of the fluxes.
