These processes include Tungsten Inert Gas (TIG) welding, Plasma Arc Welding, Submerged Arc Welding, Metal Inert Gas (MIG) welding, and Flux-Cored Arc Welding, with pulse arc welding being the preferred method. For manual arc welding, it is recommended to use a mixed shielding gas composed of Argon, Helium, Hydrogen, and Carbon Dioxide (Ar+He+H2+CO2).   The welding of Incoloy 825 must be performed in the annealed condition, and surfaces should be thoroughly cleaned with a stainless steel wire brush to remove stains, dust, and any markings. When welding at the root of the weld, great care must be taken to achieve optimal root weld quality using very high purity argon gas (99.99%) to prevent oxidation. Any discoloration in the heat-affected zone of the weld should be brushed off with a stainless steel brush before the weld area cools to remove heat tints.
