Abstract
Methods, devices and systems for laser-supported plasma cutting or plasma welding of a workpiece. In one aspect, a method includes producing a plasma beam which extends in an expansion direction between an electrode and a processing location on the workpiece, the plasma beam having, with respect to a center axis of the plasma beam that extends in the expansion direction, an inner central region and an outer edge region, and supplying laser radiation to the outer edge region of the plasma beam. The laser radiation supplied to the outer edge region extends parallel with the center axis of the plasma beam.
