PROBLEM TO BE SOLVED: To achieve the welding of nickel base superalloys without inducing high stresses, and thus reducing the formation of cracks within the weld region. SOLUTION: A buttered layer is attached to a first article formed from a superalloy. A buttered layer is attached to a second article formed from a superalloy. Residual stresses are relieved between the buttered layer and the superalloy. Matching faying surfaces are established at the buttered layers of the articles. And, the faying surfaces of the articles are welded together to form a welded assembly, wherein after welding, a heat affected zone is within the buttered layers. COPYRIGHT: (C)2008,JPO&INPIT |
