Abstract
A joint-site structure for components to be connected by overlap friction welding. At least one step of at least one component, on which an axially set-back ring-shaped joining surface is situated, is provided with a radial undercut, in such a manner that on the face side, a region of this step that is unchanged in diameter forms a radial support ridge, which is connected with the at least one component by way of a heat throttle that is reduced in cross-section. The length of each step is designed in such a manner that when the face surface of the one component makes contact with the ring-shaped joining surface of the other component, the other face surfaces of these components, which surfaces lie opposite one another in the same radial position, are still exposed until completion of the friction-welding process.
