Abstract: Systems and methods for laser welding are disclosed. A laser welding system includes a hand held laser welding tool to direct laser power to a workpiece to generate a weld during a laser welding operation. The welding system includes a controller to regulate activation and regulation of the laser power based on user inputs, sensor inputs, and/or synergic control of a laser power source.

Abstract: Systems and methods are described to address issues associated with welding with cored wires. In certain processes, a welding wire may “stick” or fuse to a contact tip, such as at termination of a weld. To mitigate the negative effects of a wire fusing to a contact tip, the wire remains in motion at a time prior to the end of the weld, as the weld ends, and/or for a time after the end of the weld, to limit and/or eliminate fusion between the wire and the contact tip.

Abstract: Disclosed is a hybrid additive manufacturing system that includes a laser system and an additive manufacturing tool, such as an arc welding type torch. The tool is configured to receive a metallic electrode wire, which is heated by a power supply to create droplets for deposition to create the part by building up successive layers of metal. The additive manufacturing system operates through coordination of the laser system to generate a laser beam, which is applied to a weld bead, and an arc welding process, which provides material for the part. A threshold value of laser intensity and/or power can be applied to the weld puddle to stabilize the arc. Through the laser beam, an arc cone position can be manipulated such that the energy into the molten pool can be redistributed.

Abstract: A method of forming an additively manufactured aluminum part includes establishing an arc between a metal-cored aluminum wire and the additively manufactured aluminum part, wherein the metal-cored aluminum wire includes a metallic sheath and a granular core disposed within the metallic sheath. The granular core comprises aluminum metal matrix nano-composites (Al-MMNCs) that comprise an aluminum metal matrix and ceramic nanoparticles. The method includes melting a portion of the metal-cored aluminum wire using the heat of the arc to form molten droplets. The method includes transferring the molten droplets to the additively manufactured aluminum part under an inert gas flow, and solidifying the molten droplets under the inert gas flow to form deposits of the additively manufactured aluminum part.

Abstract: A laser processing head includes first and second contact points connected to a power source. The power source generates a current to flow through an electrode wire between the first and second contact points to heat the electrode wire. A laser source generates one or more laser beams having lasing power sufficient to at least partially melt the electrode wire. A coaxial laser head focuses the one or more laser beams at one or more focal points on a workpiece to at least partially melt the electrode wire.

Abstract: A method and apparatus for controlling arc/short between a wire and a work piece is described. A current path parallel to the wire/work is provided. The voltage drop across the parallel path can be preset, to limit the wire/work voltage, or it can be controlled to a desired level. The control can be in response to feedback.

Abstract: A welding-type system includes a power supply configured to control preheating of an electrode wire. A controller is configured to receive a plurality of power values corresponding to a power output of the power supply and calculate an arc power value corresponding to an arc condition at the preheated electrode wire based on a rate of change of the plurality of power values. A target power output value is determined based on the calculated arc power value, and the power output is adjusted based on the determined target power value.
