A connecting seam is formed between two thin-walled sheet-metal parts as a laser weld seam or laser soldered seam as additional material is supplied, respectively. The sheet-metal parts have flange portions for formation of a connecting region. At least one flange portion includes in the region of a joining zone a bead which is at least partially surrounded or filled by solidified melt from seam material after the production of the connecting seam.
