Gas Tungsten Arc Welding (GTAW)/ (TIG) Tungsten inert gas welding process that uses non- consumable tungsten electrode to produce the weld. The weld area is protected from atmosphere contamination by an inert shielding gas(Argon or Helium) with filler metal.
Tig welding allow stronger & high quality clear welding as compare to shielded metal-arc welding.Because only the necessary amount of filler metal is added to welding puddle, no-spatter or sparks are produced. No flux being used during Tig welding so there is no slag to block your view of the weld bead. Final welding also having no slag to remove.
