摘要： A method and apparatus for providing welding type power on one of at least two output terminals is disclosed. Input power is received and welding type power is derived and provided by a shared power circuit. The welding type power is provided across a shared terminal and only two process terminals in response to a desired process. The desired process can be set bu user input, feedback, or sensing working connections. The process terminal is selected by selectively opening and closing at least two controllable switches.

摘要： Embodiments of a high speed laser hot wire spraying system are disclosed. In one embodiment, a laser subsystem includes a laser power oscillator and a laser focusing device to generate a laser beam directed toward a substrate. The laser focusing device includes a high velocity coaxial gas nozzle to direct, coaxially with the laser beam, a stream of inert gas toward the substrate. A hot wire subsystem includes a power supply and a wire feeding device to feed a consumable metal wire toward the laser beam while resistively pre-heating a distal portion of the consumable metal wire. The laser beam provides energy to liquefy the distal portion of the consumable metal wire upon intersecting the laser beam. The stream of inert gas has a velocity to cause the distal portion of the consumable metal wire to be sprayed as liquefied particles onto a surface of the substrate.

摘要： A contact device for feeding current to one or more welding wires in a welding apparatus includes a split tip nozzle having first and second diametrically opposed slots formed therein and a biasing means for supplying an adjustable biasing force to first and second split tips to bias the first and second split tips together to ensure that a desired contact between the split tip nozzle and the one or more welding wires is maintained throughout the lifecycle of the nozzle. The biasing force may be applied by any means including, for example, a compression ring, interaction of tapered surfaces between the tube and the split tip nozzle, a compression or cylinder spring pre-mounted on the first and second split tips, a tensioning screw, etc.

摘要： A welding system includes a feeder that advances a self-shielded flux-cored welding electrode toward a weld puddle. A power supply provides a welding output to the electrode to generate an arc, and a controller controls the welding output. The controller controls the power supply to provide a background welding output to the electrode before a shorting event between the electrode and a workpiece is detected. The controller monitors the welding output to detect both the shorting event and the clearance thereof. Upon detecting clearance of the short, the controller automatically switches the welding output to a minimum magnitude fixed current welding output. After the predetermined duration, the controller automatically switches the welding output from the minimum magnitude fixed current welding output back to the background welding output until another shorting event is detected.

摘要： Systems and methods for selecting a welding process are disclosed. An example welding power supply is configured to: provide welding power for welding; receive a communication from a remote device over a weld cable, wherein the communication corresponds to a detected welding output polarity; and automatically set a new welding process based on a current welding process of the welding power supply and the received communication.

摘要： A method of preventing arc flaring events for a welding system is provided. The method includes determining, by a controller, a real-time welding output characteristic of the welding system. The method additionally includes comparing, by the controller, the real-time welding output characteristic to a threshold welding output characteristic. The method further includes controlling an operating characteristic of the welding system in response to a determination that the real-time welding output characteristic exceeds the threshold welding output characteristic.

摘要： A welding torch system includes a receiving assembly to receive a contact tip and a welding nozzle. The welding torch system also includes a locking element that retains the contact tip in a partially secure position. Further, the welding torch system includes the welding nozzle configured to couple to the receiving assembly to retain the contact tip in a fully secure position.

摘要： Embodiments of systems and methods of additive manufacturing are disclosed. In one embodiment, a computer control apparatus accesses multiple planned build patterns corresponding to multiple build layers of a three-dimensional (3D) part to be additively manufactured. A metal deposition apparatus deposits metal material to form at least a portion of a build layer of the 3D part. The metal material is deposited as a beaded weave pattern, based on a planned path of a planned build pattern, under control of the computer control apparatus. A weave width, a weave frequency, and a weave dwell of the beaded weave pattern are dynamically adjusted during deposition of the beaded weave pattern. The adjustments are under control of the computer control apparatus based on the planned build pattern, as a width of the build layer varies along a length dimension of the build layer.
