ABSTRACT:
The method of repairing a metal alloy component, and the resulting repaired component. The method involves machining the component surface to remove a defect, and then placing in the resulting surface cavity a filler insert whose size and shape are predetermined so that the welding operation can be carried out to completely melt the insert while minimizing the melting of the component immediately surrounding the insert. As such, minimum mixing occurs between the materials of the insert and the component, thereby reducing the risk of cracking following the welding operation.
