Abstract
The invention relates to a method for producing a friction-welded connection between a plurality of superimposed flat components held together by a connecting member, wherein a collar of said connecting member rests on an upper component and the front end of said connecting member forms a friction-welding zone with a lower component, said friction-welding zone being produced by rotation and pressure of the connecting member. After formation of the friction-welding zone, the rotation of the connecting member ceases at the end of a first step and, in a second step, upon cessation of the rotation of the connecting member prior to contact of the collar with the upper component, a pressure is exerted on the connecting member by a pressure-applying tool, said pressure pressing the collar against the upper component because of a deformation.
