Method for producing a turbomachine part by means of a laser process

A method for producing or repairing a turbomachine part by means of a laser beam, wherein a nozzle sprays a metal powder towards a substrate so as to produce the part by successive depositions of layers on top of each other, in one direction, therefore making the nozzle follow a trajectory, and wherein the trajectory of the nozzle is initially defined in a pre-determined manner, and then, during the production of the part:

• referring to an orientation parallel to the direction of deposition of the layers, a theoretical reference distance that has been previously recorded and a real distance which is then measured are compared;
• and
• the trajectory of the nozzle is modified on the basis of a non null deviation threshold between the theoretical reference distance and the measured real distance.
