Title: METHOD AND DEVICE FOR MARKING A WORKPIECE SURFACE OF A METAL WORKPIECE USING A WELDING WIRE ELECTRODE
Abstract:
The invention relates to a method and a device for marking a workpiece surface (2A) of a metal workpiece (2), in which a welding torch (3) with a meltable welding wire electrode (4) is guided along the workpiece surface (2A) to be marked, and a wire end (4A) of the meltable welding wire electrode (4) is moved towards and away from the workpiece surface (2A) to be marked. An electrical voltage (U) applied to the welding wire electrode (4) and/or an electrical current (I) flowing through the welding wire electrode (4) generates electrical sparks that cause material to be removed from the workpiece surface (2A) of the metal workpiece (2) so as to mark the workpiece surface (2A).
