ABSTRACT:
Thin sheet metal workpieces are overlapped and a laser beam trained on the overlapping regions to heat them to a fusion temperature. The fusion seam is compressed to a maximum of 1.6 times the thickness of the sheet metal workpieces to provide a tight reliable fatigue-resistant seam of a thickness less than twice the sheet metal thickness.
