METHOD FOR JOINING TWO OR SEVERAL PROFILED PARTS OR METAL SHEETS WHICH ARE MECHANICALLY JOINED AND PRESSURE-WELDED AT ONE OR SEVERAL CONNECTION POINTS
Abstract:
Disclosed are a method for joining two or several metal sheets or profiled parts, particularly of a vehicle body segment, and a vehicle body segment. Said method for joining two or several metal sheets or profiled parts, one of which is typically made of a higher-strength steel, comprises the following steps: a) the metal sheets or profiled parts are mechanically connected in a positive and/or non-positive manner at one or several junctions, whereupon b) the junctions are thermally joined using pressure welding. The inventive method makes it possible to produce body segments that are provided with top quality spot-welded joints, especially in the motor vehicle sector.
