AWS A5.14 Class ERNiFeCr-2
718 is a nickel-chromium-columbium-molybdenum filler metal designed
specifically for TIG welding of Inconel® alloys 718, 706 and X-750. The weld deposit of 718 offers exceptional high strength and good ductility at temperatures up to 1300°F. Good weldability and formability as well as
excellent cryogenic properties account for the many applications of this filler metal. The weld deposits of 718 will precipitation-harden on heat treatment.
