Beschreibung
Zusammenfassung:	A method of producing a metal profile is provided in which a first sheet metal strip is deformed into a first profile by a plurality driven or free-running roller forming tools and, directly after the deformation process, passes through a welding station, in which a second sheet metal strip or a second profile is welded longitudinally with the first profile by means of a laser beam to form a composite profile. The second sheet metal strip, or the second profile, is hereby laid flat on the first profile, and welded on both sides along the lateral edges of the resulting contact surface. The composite profile can be produced from sheet metal strips and/or profiles with respectively different material properties. The second sheet metal strip or the second profile can be provided before welding with stampings and/or bent-up portions. A device for performing this method is also provided.
