Method and device for keyhole laser welding in combination with heating beam and filler material

摘要

The present invention relates to a method and a device for the welding, in which a seam between two metal parts at least with the aid of a welding beam is produced in the deep welding mode and in which, when welding in the region of the processing zone is supplied to a filler. Such a known process, in terms of an improved process reliability and processing speed, can be designed in such a way that the weld seam with the aid of at least of a melt stream in the heat line mode and that the filler material is processed by the processing zone at least a part of the radiation profile of the melt jet is supplied through.
