Abstract (en)

[origin: DE19620814A1] The present invention relates to a process for producing a multi-part assembly, in particular a three-part assembly, in which at least one flat metal part (1) and one metallic base (2) are pressed onto one another to form a structure (4) to be connected, a connecting part (3, 3a) with a tapering end portion (5) and of a material with a higher melting point than that of the flat metal part (1) and the structure (4) are rotated relative to one another to form a molten material (7) and are pressed against one another until the connecting part (3, 3a) has penetrated the flat metal part (1), so molten material for forming a material welded joint (9) between the base (2) and the flat metal part (1) is brought therebetween. The invention also relates to a correspondingly produced multi-part connection and the formation of an associated connecting part (3). The preferred sphere of application is the connection of light metal parts, in particular body parts in automobile construction.
