  • Publication number: 20240139878
    Abstract: The present disclosure relates to laser devices for laser metal deposition and methods for laser metal deposition. A laser device for laser metal deposition on a substrate is provided. The laser device comprises a delivery opening for delivering a metallic wire to the substrate, a laser beam source configured to emit a laser beam for fusing the metallic wire with the substrate, and a force sensor for measuring a parameter indicative of a force exerted on the laser device by the metallic wire. The laser device is configured to obtain a first indication related to a distance between the delivery opening and the substrate based on the parameter indicative of a force exerted on the laser device by the metallic wire. Methods for laser metal deposition are also provided.

  • Publication number: 20240139877
    Abstract: The present disclosure relates to laser devices for laser metal deposition and methods for laser metal deposition. A laser device for laser metal deposition on a substrate is disclosed. The laser device comprises: a delivery opening for delivering a wire or powder metallic feedstock to the substrate; a laser beam source configured to fuse the metallic feedstock with the substrate, the laser beam source being configured to emit a laser beam of a first power; a plurality of cameras configured to record images of a region of interest; and one or more light sources configured to illuminate the region of interest. The one or more light sources are configured to illuminate with a power of a blackbody radiation emitted during laser metal deposition.

  • Patent number: 11219951
    Abstract: Disclosed is a multi-mode laser device for metal manufacturing applications including additive manufacturing (AM), laser cladding, laser welding, laser cutting, laser texturing and laser polishing. The multi-mode laser device configures off-axis, solid-state diode or diode-pumped lasers into an array to perform precision controlled, direct metal deposition printing, cladding, laser welding, laser cutting, laser texturing and laser polishing through a single device. Dual-mode printing, cladding and welding capability using metal wire and powder feedstock sources in the same device is provided with in-line control, precision wire feed driver/controller, adjustable shield gas diffuser, and nozzles tailored to wire feedstock diameter.
