Claim:
A method of providing a weld treatment on a part comprising the steps of: (a) identifying a part in need of a weld treatment to correct a defect, the part being a full hoop part surrounding a central axis by 360°; (b) identifying an area of material on the part about which the part would thermally expand while not creating additional stress in the arbitrarily shaped part at the weld treatment, said identification of said area of material being made with structural analysis; (c) providing the weld treatment; (d) simultaneously providing a local heat treatment at an area receiving the weld treatment, and at the identified area; and (e) said local heat treatment at the area receiving the weld is provided across a first band, and the local heat treatment at the identified area is provided across a second band, and wherein the second band is circumferentially centered at a location spaced by 180° from a circumferential center of said first band.
