The invention relates to a method for producing integrally bladed gas turbine rotors, especially of integrally bladed turbine rotors, wherein rotating blades (10) are joined to a rotor base (11) with the intermediate disposal of an adapter (14) in such a way that first an adapter is joined to a connecting section (15) of each rotating blade to be connected to the rotor base, and that subsequently each rotating blade (10) is joined to a connecting section (16) of rotor base (11) via adapter (14) connected to said blade. According to the invention, each adapter (14) is connected to connecting section (15) of the respective rotating blade (10) by welding, each rotating blade (10) being connected to the respective connecting section of the rotor base by inductive high-frequency pressure welding via adapter (14) connected to the blade.

1. 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. 2. The method according to claim 1, wherein the adapter is connected to the rotating blade by linear friction welding. 3. The method according to claim 1, wherein the adapter is connected to the rotating blade by rotational friction welding. 4. The method according to claim 1, wherein at least joining zones are mechanically machined after the rotating blade is connected to the rotor base. 5. The method according to claim 1, wherein at least joining zones are subjected to a heat treatment after the rotating blade is connected to the rotor base. 6. The method according to claim 1, wherein an adapter made of a material suitable for fusion welding is used. 7. The method according to claim 1, wherein a rotating blade made of a material not suitable for fusion welding is joined to a rotor base made of a material suitable for fusion welding. 8. The method according to claim 1, wherein then, if the non-damaged blade is a repaired blade that has first been separated from the rotor base and repaired after separation is connected to the connecting section of the rotor base, first the section of the adapter remaining on the connecting section of the rotating blade is plane ground, subsequently it is rebuilt by laser resurfacing by welding and following this, is made into a desired contour. 9. The method according to claim 8, wherein the adapter that is rebuilt by laser resurfacing by welding is made into the desired contour by milling.
