Method for repairing a compressor rotor in blisk design

摘要

The repair protest is for a rotor made in the blisk process by joining components to form a single piece. A badly damaged stage is replaced by a new one and the rotor is then heat treated. The new blisk is electron-beam-welded to the rotor. The connection point is heat treated along with an adjacent area influenced by the welding heat, using induced current produced by electromagnetic induction.
