Abstract: Disclosed welding-type systems include a welding-type power source to generate output power for a periodic welding process that operates in an arc mode, an open circuit mode or a short circuit mode. A wire-feeder advances an electrode wire toward a workpiece. A controller adjusts the current to below a threshold value during the arc mode to result in the open circuit mode prior to occurrence of a short circuit event based on one or more welding process parameters. In some examples, the controller determines the occurrence of the short circuit event based on the one or more welding process parameters, and adjusts the current to rise above a second threshold level to adjust a heat generated in the welding wire in response to the occurrence of the short circuit.

Abstract: A method for controlling a metalworking operation. The method includes measuring a force feedback from a wire being fed from a feeder, the wire contacting a workpiece, determining a change in the force of the force feedback, and adjusting either a heating of the wire or a feed rate of the wire based at least in part on the change in the force of the force feedback. Also disclosed are apparatus for effecting the foregoing.

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 for controlling a start of a metalworking operation. The method includes detecting an initial contact between a wire being fed from a welding apparatus and a workpiece and, in response to the detection, halting feeding of the wire from the welding apparatus. The method further includes activating a high energy heat source configured to heat a tip of the wire and resuming the feeding of the wire from the welding apparatus when the tip of the wire is heated by the high energy heat source to a plastic state. The feeding of the wire is resumed by measuring a force feedback from the wire contacting the workpiece. An apparatus for implementing the method is also disclosed.
