The reliability, quality and costs of fully automated laser welding in machine building strongly depend on the cleanness of the surfaces to be joined. It is shown that laser cleaning at constant high intensity and extremely short exposure time can solve the problem. The process makes it possible to remove all foreign materials from the surface of the machinery structural elements that are to be welded together. In doing so, the optical property differences between the materials to be welded and the impurities to be removed are utilized.
