ERNiCr-6 is used for welding nickel-chromium-iron alloy such as UNS N06600 and N06075 to itself, for the clad side of joints in steel clad with nickel-chromium-iron alloy, for surfacing steel with nickel-chromium-iron weld metal, and for joining steel to nickel-base alloys using the tungsten inert gas welding, gas-shielded metal arc welding, submerged arc welding, and plasma arc welding.
