Problems solved by technology

As a result, sufficient heat is no longer available for nucleation of the solder joint, so a reduction in connection formation occurs
In addition, angular or lateral offsets of the spot welding electrodes lead to deflection of the joining aid

Embodiment Construction

[0032] exist figure 1 The produced component connection is shown in , in which an aluminum panel part 1 is connected as a first joint partner to a steel panel part 3 as a second joint partner. The two joint partners 1 , 3 are connected to each other via the joint aid element 5 . Furthermore, an adhesive layer 7 is arranged between the two joining partners 1 , 3 . The material pairings described above are purely exemplary. Alternatively, any other desired material is also conceivable, for example magnesium, possibly also plastic.

[0033] According to the figures, the joining aid element 5 is designed with a hollow element neck 9 and an element head 11 . exist figure 1 While maintaining the remaining material thickness r, the element neck 9 is press-fitted into the material of the aluminum sheet part (first joining partner) 1 in the mounting step I described later. In contrast, the element head 11 of the joining auxiliary element 5 is welded to the second component (steel ...

Abstract

The invention relates to a method for joining at least two components (1, 3), said method having a setting step (I) and a joining step (II), in the setting step while maintaining a remaining material thickness (r) Next, the joining aid element (5) is press-fitted into the first component (1), and the joining aid element (5) press-fitted in the first component (1) is connected to the second component (3) in the joining step. The joining aid element (5) is designed with a hollow element neck (9) and an element head (11), which is press-fitted in the first component (1), and said element head is connected to the second component ( 3) Welding or bonding.

Description

technical field [0001] The invention relates to a joining aid for a method of joining at least two components. Background technique [0002] In automobile construction, vehicle bodies can be produced in hybrid constructions in which, for example, aluminum semi-finished products are joined together with steel semi-finished products. The semi-finished products are preferably connectable to one another by mechanical joining methods (that is to say without structural transformation), such as semi-hollow steel rivets, wherein the semi-hollow punch riveting elements pass through the first component in the riveting direction during the riveting process and Press-fitted in the second component, for example while maintaining a remaining material thickness in the second component. Such a semi-hollow punch rivet is described, for example, in EP 231 4890 A2. For the highest strength steels, these semi-hollow punch rivets do not provide sufficient joint quality due to the very high mat...
