GEN 617 Overview
GEN 617 is used for TIG, MIG, and SAW welding of nickel-chrome-cobalt-molybdenum alloys as well as between themselves and dissimilar metals, such as stainless, carbon or low alloy steels. This filler wire also can be used to overlay welding where similar chemical composition is desired. The weld metal provides optimum strength and oxidation resistance from 1500°F (815°C) up to 2100°F (1150°C).
