In a process of layer welding, it is provided a device (1) comprising a calibration unit (30) adapted to guide an emitted laser beam (10) along a first optical axis (10a) and comprising refraction means (32a, 32b) adapted to be passed through by the laser beam (10) and to deviate it along a second optical axis (10b) different from the first optical axis (10a); a guide structure engaging the refraction means (32a, 32b) and suitable to enable them to carry out a first movement in which the mutual arrangement of the optical axes (10a, 10b) is maintained constant; and actuating members (34) adapted to impose the first movement of the refraction means (32a, 32b). |
