Abstract: A method connects at least two components made of different materials by thermal joining. The two components include a first component made of a material that is suitable for thermal joining and a second component made of a material that cannot be processed using the thermal joining method of the first component. The method includes introducing an auxiliary joining part into the second component forming a form-locking connection and/or a force locking connection. The auxiliary joining part of is made of a material that can be thermally joined to the first component. The first component is thermally joined to the auxiliary joining part in the second component so as to produce a connection between the first component and the second component. The thermal joining is carried out by a beam welding method.

Abstract: The invention relates to a method for connecting at least two sheet metal parts (1, 5), wherein an impressing/press-insertion element is fastened to the first sheet metal part (1) and then the impressing/press-insertion element (3) fastened to the first sheet metal part (1) is welded to the second sheet metal part (5), in particular by spot welding. According to the invention, in order to fasten the impressing/press-insertion element to the first sheet metal part (1), the impressing/press-insertion element (3) is pressed into the material of the first sheet metal part (1) in a deep-drawing direction (T) in a deep-drawing process and enters into a form-locked connection to the first sheet metal part (1) under plastic deformation.
