    Description: The invention relates to a friction-welded connection of at least two superimposed plate-shaped components, of which the lowermost component consists of high-strength steel with a tensile strength of greater than 1000 megapascal and the upper component or components of permeable material, in particular light metal, which are penetrated by a Reibschweißelement which is connected via a Reibschweißverbindung with the lowermost component.
    Such Reibschweißverbindung is known from DE 10 2006 013 529.1. This friction-welded joint is a lower component made of steel and an upper component made of aluminum or plastic. The friction-welding element itself is made of steel which has received the desired friction-welded connection with the lower component. Applications of such Reibschweißverbindungen are plate designs, on the one hand have a high strength and on the other hand are resistant to weathering, as is required for example for body panels. Such a design is disclosed both in DE 10 2006 013 529 A1 and DE 10 2009 006 775 A1. It is pointed out in the latter document under Section 0027 that the first (top) sheet metal component consists of a softer material than the second (lower) sheet metal component 40. For example, it may be in the first component to an aluminum sheet and the second component to act a steel sheet.
    The invention has for its object to provide a material composition that optimally meets the demands placed on them and not only has the necessary properties of the environment opposite, but also ensures the production of Reibschweißverbindung with high security. According to the invention, this is achieved in that the friction welding element (2) of alloyed steel with carbon contents of 0.17% to 0.45%, chromium of 0.70% to 1.5% and molybdenum of 0.15% to 0.80%, wherein the friction-welding element additionally contains vanadium in a proportion of 0.20% to 0.35% and has a tensile strength greater than 1000 megapascals.
    In this design, the Reibschweißverbindung the material of Reibschweißelementes plays a special role insofar as it penetrate one hand without their own change the upper components by plasticizing, can easily rub through a possible coating of the lowermost component and enters into a Reibschweißverbindung with the bottom component, which is characterized by particular toughness and strength and thus gives the created by the friction-welded joint plate composite very high strength. The connecting material is therefore particularly suitable for the production of automobile bodies, since it is particularly stable because of the use of high-strength steel and provides the desired lightweight construction.
    A suitable design for the present invention is such. For example, in DE 10 2006 013 529, Figures 4, 5 and 6, wherein, however, only two plate-shaped components are provided for the composite material, namely for the upper part of a relatively soft material and the lower material is a high-strength harder material (see there Section 0037).
    The particular composition of the friction welding according to the invention gives this the property of initially despite the melt through the or the upper components themselves not practically lose in hardness, so that the Durchdringungsvorgang itself can be undisturbed. Even when the friction welding element strikes the lowermost component, the former initially largely retains its strength until friction welding of the latter component, which also leads to welding of the friction welding element only during the actual friction welding of the lowermost component. This is for the safe operation of the production of the friction-welded connection of particular importance and can not be reliably ensured when using a manganese and / or drilling steel due to its low strength goods, such as this material use in the aforementioned DE 10 2009 006 775 in section 0014 is mentioned.
    In the figure, an embodiment of the finished design of a Reibschweißverbindung is shown according to the invention. The figure shows the bolt 1, which is shown with its connecting element 2 on the assembly of an upper plate 3 and a lower plate 4, wherein the plates 3 and 4 represent the component in which the plates 3 and 4 are interconnected by a friction-welded connection , The plate 3 is an aluminum plate, the plate 4 is a steel plate. The connecting element 2 has passed with its projection 5 through the plate 2 during the friction welding process and has finally reached the plate 4, where due to rotation and pressure, the friction welding zone 60 has resulted. The plate 3 is pressed against the plate 4 permanently on the Reibschweißelement 2 with the shoulder 7 against the plate 4, so that at the end of the Reibschweißvorganges a Reibschweißverbindung 6 given solid connection between the two plates 3 and 4 is made.
