Claim Text:
1. A method comprising: selecting an alloy feed material and a flux material for cladding a substrate, wherein the alloy feed material and the substrate each comprise a superalloy composition beyond a zone of weldability defined on a graph of superalloys plotting titanium content verses aluminum content, wherein the zone of weldability is upper bounded by a line intersecting the titanium content axis at 6 wt. % and intersecting the aluminum content axis at 3 wt. %; disposing the alloy feed material and the flux material on the substrate; melting the alloy feed material and the flux material with an energy beam or an arc to form a weld pool on the substrate; and allowing the weld pool to solidify and cool on the substrate as a layer of superalloy cladding covered by a layer of slag.
