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.

Abstract: A system for automatically brazing joints in a manifold has a loading station, a brazing station, and a cooling station. The brazing station has a plurality of brazing torches moveable to a joint in the manifold to braze the joint. First, second and third fixture frames extend from a common rotatable platform. The platform rotates each of the fixture frames to each of the loading station, brazing station, and cooling station in turn. The fixture frames support manifolds with joints requiring brazing. The torches are disposed on a lifting platform that lifts the torches up to a desired joint. The lifting platform is disposed on a sliding platform that slides the torches horizontally to the desired joint. The torches surround the joint and braze it from all sides simultaneously. While brazing is being performed at the brazing station, loading and unloading of manifolds may be done at the loading station, and cooling of already-brazed manifolds may take place at the cooling station.
