Process for manufacturing welded steel plate panels

摘要

A method of producing laser or electron beam welded steel sheets from stamped sections with non-linear weld seams, involves (a) press-forming shallow domes into one or more of the sections before stamping; (b) arranging the sections in pairs; and (c) pressing the domes against a support so that the welding edges of these sections adjoin the edges of another section. Preferably, the assembled edges are initially tack welded and then seam welded by a laser. When a plate of three or more parts is to be produced, at least two sections with preformed domes are preferably provided for correcting shape errors of the welding edges.
