Abstract A method of welding superalloy components comprising: (a) forming a weld prep groove at an interface of the components; (b) welding the components using a filler material at ambient temperature; (c) covering the filler material and adjacent surfaces of the components with a braze paste; and (d) heat treating the components, the heat treatment including a stress-relief cycle and a braze cycle. A similar process may be used to repair a crack in a nickel-based superalloy component.
