Abstract
A method of forming a welded assembly, wherein an electron beam is used to form a weldment that joins two or more articles to form the welded assembly. The method involves directing a second electron beam onto the weldment in the wake of the welding beam, in a manner that inhibits precipitation of a solutioned precipitation-strengthening phase so as to reduce the incidence of strain-age cracking in the weldment.
