Abstract: A fusion welded surfacing process for use with crack prone substrates is described. The process involves the application of an intermediate layer of crack resistant alloy by fusion welding followed by the application of the desired final surfacing alloy by fusion welding. The intermediate layer is an age hardenable nickel superalloy to which intentional additions of manganese have been mate. The final surfacing alloy may be of the hardfacing type or may be of a type which imparts corrosion and oxidation resistance to the underlying article.

Abstract: A class of age hardenable nickel base alloys for use as filler wires in fusion welding superalloys is described. The alloys contain manganese in levels of from about .5 to 3 percent to greatly reduce the incidence of heat-affected zone cracking in the metal being welded. The weld filler alloys also contain significant amounts of aluminum, titanium, tantalum, and columbium, and therefore the resultant welds can be age hardened to relatively high strength levels. Method for reducing cracking during fusion welding using above alloys are also disclosed.

Abstract: A wire of a normally nonforgeable composition, having improved resistance to fracture during working, handling and use is comprised of a portion with a rapidly quenched structure as a continuous stratum along its length. A preferred wire useful for fusion welding has a circular cross section with a micro-crystalline surface portion of at least 30 volume percent of the wire. Other preferred wires have elliptical or rectangular cross sections with amorphous strata continuous along their lengths.
