ABSTRACT:
A laser operation such as a laser welding operation or a laser cutting operation is improved in its quality and a consistently high quality is achieved by arranging auxiliary tool units upstream and/or downstream of a main laser tool unit including a primary laser head on a common tool carrier. The secondary tool units upstream of the laser operation are intended for a preliminary surface treatment to present the most appropriate surface conditions for the following laser operation. Similarly, the tool units arranged downstream of the laser operation are intended for subsequent work operations such as an immediate cleaning operation, a coating operation or the like to avoid a reoxidation of the welding seam or of the cut edge of the work piece. The secondary tools make sure that the laser operation is enhanced or improved either by presenting optimal conditions for the laser operation or by improving the work piece subsequent to the laser operation. The subsequent operation in this sense also results in an improved laser operation.
