Abstract
The invention relates to a friction weld assembly of a plurality of superposed plates, said plates being held together by a connection body which rests on the upper plate by means of a collar and is formed as a slender cone ending in a tip. The connection body comprises a driving element in the region of the collar thereof, for the attachment of a pressure and rotation tool. A girder formed from the slender cone and penetrating from the upper plate into the lower plate, and a girder protruding from the lower plate along the inner surfaces thereof, form a friction welding region extending onto the slender cone.
