Abstract
A laser processing machine adapted for joining two metal workpieces includes a laser processing head and two workpiece holders. The workpiece holders hold the workpieces in contact with each other and cause relative motion between the workpieces to generate frictional heat to preheat the surfaces of the workpieces to be joined with energy directed from the laser processing head.
