  • Welding unit with miniaturized laser beam
    Patent number: 7038161
    Abstract: The invention provides a welding device (10) using a power laser beam (22), the device (10) being miniaturized, the device (10) being suitable for being moved very close to the surface (52a) of the part (52) to be welded and of reaching welding zones that are difficult to access, but without vapor and particles of molten metal (56) being capable of penetrating into the inside and dirtying the optical components (28, 48, 46). Such a device is remarkable in that it includes a feed (26) of gas under pressure suitable for producing a primary flow of gas (50) leaving via the front opening (20) together with the laser beam (22), and in that it also includes a nozzle (60) connectable to a source of gas under pressure, said nozzle (60) producing a secondary flow of gas (62) sweeping the front opening (20) transversely, thereby deflecting the primary flow of gas (50) laterally.
