Abstract: The invention discloses a method and a production installation for producing a sub-assembly consisting of a plurality of parts joined together, in which the first part (1) and second part (2) are removed from a parts delivery site in the vicinity of a transport device and deposited oriented in position on one of a plurality of parts transport carriers of the transport device, and subsequently together with the parts transport carrier transported to an assembly station. The parts transport carrier is stopped in the assembly station in a holding position, whereupon the parts (1, 2), oriented towards one another, are moved by means of a vertical positioning device (200a, 200b) together from a transport position on the parts transport carrier into a preparation position, then positioned relative to one another, clamped and then joined to form a sub-assembly, whereupon the joined subassembly is again deposited on one of a plurality of parts transport carriers and transported away thereby.

Abstract: The invention relates to an assembly (1) and a method for producing the latter, with a first and second part (2, 3), the first part (2, 3) of which is cold formed and the parts (2, 3) with parallel surface parts (20, 21) and mounting surfaces running at an angle to the latter are provided for arranging them relative to one another without a gap and are joined together at the joint (16) by a weld (17) produced by beam welding. The surface parts (20, 21) are arranged offset relative to one another by an offset (19). One of the parts (2, 3) comprises a mounting projection (6), which forms the mounting surface of the first part (2). The parts (2, 3) are positioned relative to one another so that the second part (3) forms the joint (16) with the first part (2) in the section of the first part (2) at which the dislocation density of the base material is lower than the dislocation density of the joint in a deformation area (18) on the first part (2) produced by cold forming.
