ABSTRACT:
Repair of compressor blades (6) of aircraft engines is performed by build-up welding against an essentially horizontal backing (8) whose surface shape is the exact negative of the respective bottom side of the blade to be repaired. With low rework effort, the blades of blisks can, in the installed state, be repaired or fully restored at any point with high quality upon removal of the damaged portion.
