摘要： A method includes receiving welding data corresponding to a welding session completed with a welding system, receiving a selected location from an operator, and displaying on a display one or more quality characteristics of the welding session corresponding to the selected location. The welding data includes welding parameters and quality characteristics corresponding to a plurality of points along a path of the welding session. The welding parameters include a work angle of a welding torch, a travel angle of the welding torch, a contact tip to work distance, a travel speed of the welding torch along the path of the welding session, an aim of the welding torch, or any combination thereof. The quality characteristics include porosity, undercut, spatter, underfill, overfill, or any combination thereof. The selected location corresponds to a point of the plurality of points along the path of the welding session.

摘要： An arc welding control method for controlling welding in which a material of a welding wire is aluminum or an aluminum alloy, and a feed speed Fw of the welding wire is alternately switched between a forward feed period and a reverse feed period to repeat a short circuit period and an arc period, a welding current Iw is controlled so that an average value of maximum values of the welding current Iw during the short circuit period is 150 A or less. A reverse feed peak value Wrp during the reverse feed period is set so that an average value of time lengths of the short circuit period is 7 ms or less. Accordingly, the current value can be reduced when the short circuit is released and the lengthening in the short circuit period can be prevented, so that the spatter generation amount can be reduced.

摘要： Some examples include a computing device that receives optical signal information based on respective optical signals received through a plurality of optical fibers during a welding operation. For example, the plurality of optical fibers may be positioned to receive electromagnetic radiation from a weld area during the welding operation. The computing device may compare the optical signal information corresponding to a first one of the optical fibers with the optical signal information corresponding to a second one of the optical fibers. Based at least partially on the comparing, the computing device may determine whether at least one of a weld geometry or a welding arc is irregular. The computing device may perform at least one action based on determining that at least one of the weld geometry or the welding arc is irregular.

摘要： A self-adjusting wire feeder mounting assembly includes a mount fixedly connectable to a multi-axis robotic arm, and a slidable, floating adapter plate for mounting of a wire feeder thereon. The adapter plate is coupled with and slidable about the mount, and the adapter plate is moveable relative to the mount when a force is applied to the wire feeder.

摘要： A welding wire feeder includes a welding wire feed drive configured to drive welding wire towards a welding application, wire feed control circuitry coupled to and configured to control the welding wire feed drive. The welding wire feeder includes power conversion circuitry configured to receive polarized input power from a welding power source via input connections with defined polarities and to convert the polarized input power to welding output, sensing circuitry configured to detect the polarity of the polarized input power when connected to the input connections, and welding process control circuitry. The welding process control circuitry is coupled to the power conversion circuitry and the sensing circuitry. The welding process control circuitry is configured to provide the polarized input power to the power conversion circuitry only if the polarity of the polarized input power corresponds to the defined polarities of the input connections.

摘要： An electric arc welding system and method includes providing a welding apparatus having at least a welding power supply, a wire feeder configured to supply a welding wire, a welding gun having an opening from which the welding wire extends, and a welding controller. The controller can initiate a weld ending process, which senses any contact between the welding wire and a workpiece. In response to any such contact, the controller executes a wire material transfer routine to transfer molten material of the welding wire from the welding wire to the workpiece. This routine can be repeated until the wire feeder stops advancing the welding wire towards the workpiece during the weld ending process.

摘要： An arc welding power supply supplies power to a welding wire functioning as a discharge electrode to generate an arc from an electrode distal end of the welding wire and perform arc welding on a welded article. The arc welding power supply includes an output control unit that adjusts the power supplied to the welding wire to a power value suitable for arc welding. A feed control unit cyclically changes a feeding speed of the welding wire. The feeding speed includes a forward feeding speed and a rearward feeding speed. An amplitude control unit cyclically changes an amplitude of the feeding speed of the welding wire to cyclically vary an average arc length.

摘要： A system includes a welding device, one or more cameras, and a controller coupled to the one or more cameras. The welding device includes a first set of visual markers oriented in a first direction and a second set of visual markers oriented in a second direction. Each set of visual markers includes at least three visual markers. The one or more cameras are configured to observe the first set of visual markers when the first direction is directed toward the one or more cameras, and to observe the second set of visual markers when the second direction is directed toward the one or more cameras. The controller is configured to track a position and an orientation of the welding device based at least in part on detection of a threshold quantity of the first set of visual markers or the threshold quantity of the second set of visual markers.
