Special Metallurgical Welding Considerations for Nickel and Cobalt Alloys and Superalloys

Abstract: The process of making assemblies of solid-solution and precipitation hardening groups of alloys and superalloys often requires welding of dissimilar metals, welding of diffusion-bonded materials, and sometimes weld overlay cladding and even thermal spraying that in turn requires special knowledge and treatments developed specifically for each material. This article emphasizes the special metallurgical welding considerations for welding solid-solution and precipitation hardening nickel alloys, cobalt alloys, an… Show more

“…Much work on printability is an extension upon weldability research, where weldability is defined by the American Welding Society as the capacity of a metal to be welded under fabrication conditions into a specific structure and for it to subsequently perform in its intended service [7] . Welding and the AM processes detailed are processes using a laser source to melt metal, so despite their differences, the wealth of literature published on weldability of nickel superalloys should be considered when investigating printability; this includes literature on both weldability testing [8][9][10] and literature focussing on nickel superalloy development/weldability [9,[11][12][13][14] .…”
