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.
