ABSTRACT:
Method and apparatus for welding a plurality of parallel continuous seams on workpieces which comprise the steps of defining a welding station including a laser beam or electron beam welding source and a focal plane spaced from the welding source and wherein the focal plane is perpendicular and intersects a plane containing the radiation welding source. The welding source spans a welding zone defined at the intersection of the focal plane and the plane contains the welding source. The seams are maintained to be welded spaced apart and parallel and moving at least one of the welding stations and the several workpieces, in unison, relative to one another such that the seams to be welded pass through the welding zone whereby welded seams are formed continuously on the workpieces.
