Abstract
Laser welding process and apparatus wherein a plurality of laser beams are focussed by a focussing device on surfaces of workpieces such that spots of the laser beams are located in the vicinity of an interface as viewed in a direction perpendicular to a direction of extension of an interface of the workpiece, and the beam spots and the workpieces are fed relative to each other by a feeding device in the direction of extension of the interface, while at the same time the beam spots are oscillated by an oscillating device at a predetermined frequency relative to the workpieces in a direction intersecting the direction of extension of the interface such that the beam spots are moved across the interface.
