ABSTRACT:
To make it possible to carry out different types of surface treatment by laser, with powder supply or addition, such as surface depositiotn, alloying or incrustation, a nozzle (12) is proposed, whose body (16) can occupy an axially regulatable position with respect to the support (10) in which is located the focussing lens for the laser beam (F). In addition, the body (16) supports a protective skirt (56), whose axial position is also regulatable and which can be brought into contact with the surface of the substrate (S).
