Alloy 601 is used for the welding of Inconel® alloy 601. The GTAW process with 601 is the only recommended joining method for applications involving temperature over 2100ºF (1150ºC) or for applications at lower temperatures involving exposure to hydrogen sulfur dioxide. The weld metal of this filler metal is comparable to the base metal in resistance to corrosion and oxidation.
