LASER-ASSISTED PLASMA CUTTING OR PLASMA WELDING METHOD, AND DEVICE FOR THIS PURPOSE

摘要

The invention relates to a method for the laser-assisted plasma cutting or plasma welding of a workpiece (3), having the following steps: generating a plasma jet (1) which extends between an electrode (2) and a machining point on the workpiece (3), said plasma jet (1) having a central region (4) which is internal relative to a plasma jet central axis (M) that runs in the propagation direction (Z) and having an external edge region (6); and conducting laser radiation (7) into the edge region (6) of the plasma jet (1), the laser radiation (7) which is conducted into the edge region (6) running parallel to the central axis (M). The invention also relates to a corresponding device (10) which is designed for laser-assisted plasma cutting and/or plasma welding.
