Abstract
Connector components, such as pipes, rods or semi-finished products is performed by friction welding with the steps of using a friction element which is arranged in an abutting position between those ends of the components which are to be connected and is rotated about an axis which is common to the components and to the friction element in order to produce a welding temperature by friction heat with compression forces which at the same time act on contact surfaces between the friction element and the component ends, subjecting the connecting component, for adjoining process, after the rotary movement has been stopped to higher compression forces in opposite directions, after reaching the welding temperature within a virtually steady-state temperature area, continuing the welding process with a material of the friction element being removed on surfaces which are involved with the friction process, until the ends of the components to be joined come into contact with one another, thereafter subjecting the components to an increased contact pressure and welding to one another by upsetting, and removing a friction and upsetting burr produced during the friction and upsetting, at the sa…
