Apparatus for coating a workpiece using a laser device

Abstract

The invention relates to an apparatus for coating a workpiece, having at least the following components: a laser device for generating a laser beam with a laser focus; a powder nozzle; and an advancing actuator system for advancing the laser device and the powder nozzle, wherein the laser device is designed for thermally treating powder material supplied by the powder nozzle for coating a surface of a workpiece and/or for thermally treating this surface. The apparatus also has: —a measuring device for recording coordinates of a point on a surface to be coated; and at least one adjusting device for adjusting the laser focus and the powder nozzle relative to one another. With the workpiece proposed here and the associated reference mark, high-precision application of a finishing layer to the workpiece can be carried out.
