1. A method for repairing a turbomachine component, the method comprising:
setting up a laser cladding machine comprising a laser source, a powder feeder, and an air source, the laser cladding machine being configured in such a way that a laser beam, a powder jet, and an air jet, respectively generated by the laser source, the powder feeder, and the air source), converge on an area to be repaired within a narrow recess of the turbomachine component; defining a path comprising areas to be repaired by laser cladding within the narrow recess, the path being extended between a first end point and a second end point; moving forward one of the laser cladding machine and the turbomachine component relative to the other of the laser cladding machine and the turbomachine component, in order that the path is covered from the first end point to the second end point by the laser beam and the powder jet for repairing the areas to be repaired; and moving backward one of the laser cladding machine and the turbomachine component relative to the other of the laser cladding machine and the turbomachine component, in order that the path is covered from the second end point to the first end point by the air jet for blowing away the powder in excess from the narrow recess. |
