Title: Method of weld repairing a component and component repaired thereby

Abstract: The method of repairing a metal alloy component, and the resulting repairedcomponent. The method involves machining the component surface to remove adefect, and then placing in the resulting surface cavity a filler insertwhose size and shape are predetermined so that the welding operation canbe carried out to completely melt the insert while minimizing the meltingof the component immediately surrounding the insert. As such, minimummixing occurs between the materials of the insert and the component,thereby reducing the risk of cracking following the welding operation.
