PROBLEM TO BE SOLVED: To provide a method for producing a sandwich structure between metal and nonmetallic materials in which, on the one hand a considerable layer thickness of a nonmetallic material is applied to a metal material, in such a manner that it bonds stably and is insensitive to impacts, and on the other hand, the method at the same time is simple to implement. SOLUTION: A bond layer 3 is produced from individual prefabricated rivets 4 which have a mushroom-like shape with stem 8 and head 9, and the rivets are welded by the stems 8 onto the surface 10 of a base body 2. The method for producing the sandwich structure is characterized in that the rivets 4 are prefabricated in a first process, in a second process the rivets 4 are sorted for mechanical downstream processing, oriented and introduced into a welding unit 15, and in a third process, the rivets 4 are successively welded, in each case by means of the free end of their stem 8, onto the surface 10 of the metallic base body 2, thereby forming the anchor points for the nonmetallic material 5. |
