ABSTRACT:
A method of repairing a turbomachine blisk having at least one damaged zone by build-up of metal in the damaged zone using a laser build-up welding machine is disclosed. The method includes preparing the damaged zone by machining the damaged zone to obtain a zone of defined profile to be repaired, build-up welding of a start-of-run test piece that includes the defined profile using the laser build-up welding machine, checking geometric and metallurgical quality of the test piece, and build-up welding the zone to be repaired of the blisk using the laser build-up welding machine.
