Abstract

The invention is directed to a friction welding process for mounting blades of a rotor for a flow machine. A plurality of oblong welding surfaces are provided at a circumferential surface of a carrier and are respectively welded to a welding surface of a blade. The welding temperature is generated by pressing the welding surfaces together and by an oscillating relative motion between the blade and the carrier in the welding plane. At least the blade or the carrier is additionally heated to a temperature lying below the welding temperature in the region of the welding surface.
