Abstract (en)
[origin: WO2011035772A1] The invention relates to a method for repairing an integral rotor (10), in particular a rotor (10) of a gas turbine, having a main rotor body (12) and a plurality of blades (14), the method comprising the following method steps: separating a blade (16) to be replaced from the rotor (10), wherein a blade stub (20) protruding from the main rotor body (12) and having a first welding contact surface (22) is formed; providing a replacement blade (24) having a second welding contact surface (26); attaching a collar (28) to the blade stub (20) and/or to the replacement blade (24) by a thermal spraying method, wherein the material of the collar (28) has a melting point that substantially corresponds to that of the blade stub (20) or of the replacement blade (24); welding the replacement blade (24) onto the blade stub (20); and at least partially removing the collar (28).
