INCONEL WELDING ELECTRODE 122 is a highly alloyed product used for joining Inconel alloy 622 (See Alloy Digest Ni-382, May 1990) and similar corrosion resistant grades. In dissimilar welding, it can be used to prevent preferential weld metal attack. This datasheet provides information on composition, physical properties, hardness, and tensile properties as well as fracture toughness. It also includes information on corrosion resistance as well as joining. Filing Code: Ni-407. Producer or source: Inco Alloys International Inc..
