Abstract: Systems and methods of a laser welding device to weld aluminum are disclosed. The device includes a laser generator to generate welding-type lasing power and a lens to focus the welding-type lasing power at a focal point on an aluminum workpiece to generate a weld puddle. A laser scanner to control the lens to move the focal point of the welding-type lasing power in multiple dimensions over the aluminum workpiece during welding, the laser generator and the laser scanner to perform the welding without filler metal being added to the workpiece.

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: Systems and methods for laser welding are disclosed. A laser welding system includes a manually operated laser welding torch to direct laser power to a workpiece to generate a puddle 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 of a laser welding device are disclosed. The laser welding device includes a laser generator configured to generate welding-type lasing power. A lens focuses the welding-type lasing power at a focal point on a workpiece to generate a puddle during a welding-type operation. A wire feeder is configured to feed wire to the puddle generated by the laser generator. A laser scanner controls the lens to move the focal point of the welding-type lasing power in multiple dimensions over the workpiece during the welding-type operation. In some examples, the feed wire is used in an additive manufacturing process.

Abstract: Disclosed is a welding system configured to perform additive manufacturing, particularly by employing an additive manufacturing tool to build up a part by employing welding-type programs. In some examples, control circuitry controls the additive manufacturing tool to operate in a first welding-type program of a plurality of welding-type programs in response to a determination that the measured temperature is below a first threshold temperature of one or more threshold temperatures, and control the additive manufacturing tool to operate in a second welding-type program of the plurality of welding-type programs in response to a determination that the measured temperature is above the first threshold temperature.
