ABSTRACT:
A method of welding aluminum alloy workpieces includes the pretreatment of an area adjacent to the seam of the workpiece followed by irradiation of the area with an infrared laser beam having a diameter equal to or greater than the thickness of the workpieces. Substantial subsurface melting of the workpieces is initially generated and the beam can subsequently be scanned along the seam so as to maintain an isotherm corresponding to the melting point of the workpiece at the leading edge of the beam.
