METHOD FOR PRODUCING AN INTEGRALLY BLADED ROTOR USING ARCUATE FRICTION WELDING, DEVICE FOR CARRYING OUT SAID METHOD, AND ROTOR PRODUCED BY MEANS OF SAID METHOD

A method for producing an integrally bladed rotor, in particular a gas turbine rotor, comprises the following steps:-Providing a blade (12) having a lower blade foot that has a joining surface (18);-Retaining the blade (12) in a retaining unit (20); and-Exciting the blade (12) to oscillate about an...

Zusammenfassung:A method for producing an integrally bladed rotor, in particular a gas turbine rotor, comprises the following steps:-Providing a blade (12) having a lower blade foot that has a joining surface (18);-Retaining the blade (12) in a retaining unit (20); and-Exciting the blade (12) to oscillate about an axis of rotation. A device for carrying out the method comprises a retaining unit, in which blade (12) can be solidly clamped in place, and an oscillating unit (24) that transmits translational oscillations to the retaining unit in a plane substantially parallel to joining surface (18), and a fixation unit (30) for establishing the axis of rotation.
