Patent ID: 8360302

Claim:
A method for repairing integrally bladed turbine rotors, wherein a rotating blade, having a connecting section, is joined to a rotor base, having a connecting section, with the intermediate disposal of an adapter in such a way that the adapter is joined to the connecting section of the rotating blade to be connected to the rotor base, and that subsequently, the rotating blade is joined via the adapter connecting thereto to the connecting section of the rotor base, wherein the adapter is connected to the connecting section of the rotating blade by friction welding, and that the rotating blade is connected to the connecting section of the rotor base via the adapter connected to the blade by inductive high-frequency pressure welding; and wherein a damaged rotating blade is separated from the rotor base in such a way that the adapter is separated, and that subsequently any remaining section of the adapter is completely removed from the connecting section of the rotor base and, following that, a non-damaged rotating blade is connected to the connecting section of the rotor base so that an adapter connected to the non-damaged rotating blade is connected to the connecting section of the rotor base by inductive high-frequency pressure welding.
