Embodiment Construction

[0045] According to the figures, firstly a first metal plate 1 and a second metal plate 2 are arranged to be connected to each other and form an assembly. The first metal sheet 1 shown and the second metal sheet 2 shown here both consist of high-strength steel. The two metal plates have a thickness of approximately 1.5 mm.

[0046] Next, the first sheet metal 1 and the second sheet metal 2 are introduced into the piercing riveting assembly tool 3 . The piercing riveting tool 3 comprises a feed nose 4 in which a punch is arranged. The feed lug 4 guides the punch 5 at the bottom end of which a piercing rivet 6 is provided. A feed lug 4 in which the punch 5 is positioned and a guided piercing rivet 6 are located above the assembly for joining the first 1 and second 2 metal sheets together. Below the components to be joined is the mold 7 .

[0047] After the first sheet metal 1 and the second sheet metal 2 have been introduced into the piercing riveting assembly tool 3 as show...

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.

Description

technical field [0001] The invention relates to a method for joining two or more sheet metal and / or profile parts. The invention relates in particular to a method for joining two or more metal sheets and / or profiles, at least one of which consists of high-strength steel. Welding of sheet metal and / or profile parts, in particular pressure welding of sheet metal and / or profile parts, is a particularly economical method, since it can be done quickly without major outlay for equipment and enables permanent bonding connect. Background technique [0002] However, welding can only be used to a limited extent, since its basic prerequisite is that the materials to be welded are well welded together. Primarily, identical or substantially identical metals and metal alloys can be welded to each other. Dissimilar metals or alloys such as aluminum and steel or copper and steel can be welded together only with difficulty or not at all. [0003] Furthermore, not only steels of different...
