摘要： A system and method of electric arc welding that includes a welding apparatus having an electric arc welder torch with sensors to determine the absolute position of the torch tip and the relative position of the torch tip to the weld joint during automatic welding. Combining absolute and relative positional data can be used to adjust the path of the robot during automated or robotic welding in response to variations in the weld joint.

摘要： Some examples of the present disclosure relate to welding torches having a thermal insulating plate (400). The thermal insulating plate is comprised of a thermally insulating material, and is positioned between a front housing (302) and a drive gearbox (324) of the welding torch. The front housing (302) is connected to a gooseneck that conducts electrical energy to a torch tip (i.e. front end) of the welding torch. The drive gearbox (324) includes a gear assembly configured to drive a drive roll that moves a wire electrode through the welding torch (e.g. toward the torch tip of the torch). The thermal insulating plate (400) acts as a heat dam to decrease and/or reduce thermal energy transfer from the torch tip of the welding torch (e.g. via the front housing) towards the rear of the welding torch (e.g. through the drive gearbox), where the thermal energy may heat the welding torch handle and/or damage some of the more expensive and/or sensitive components in the handle (e.g. a motor of the drive gearbox).

摘要： An orientation and guide mechanism for a welding system includes a pair of opposed guide members. A weld wire having a non-round cross-section is fed through a guide passageway formed between the guide members, each of which have recessed channels that combine to define the guide passageway. The guide passageway has a non-round shape corresponding to the non-round shape of the wire. The orientation mechanism and the guide members thereof is adjustable relative to a welding device of the weld system, such that the orientation of the wire can be controlled and maintained by adjusting the orientation mechanism. The wide side of the wire may be adjusted to be presented to a radiant energy source, and/or the non-round wire may be adjusted relative to the desired weld seam.

摘要： A welding or additive manufacturing system includes a contact tip assembly having first and second exit orifices. A wire feeder is configured to deliver a first and second wire electrodes through the exit orifices. An arc generation power supply is configured to output a current waveform to the wire electrodes simultaneously, through the contact tip assembly. The current waveform includes a bridging current portion, and a background current portion having a lower current level than the bridging current portion. The bridging current portion has a current level sufficient to form a bridge droplet between the wire electrodes before the bridge droplet is transferred to a molten puddle during a deposition operation. Solid portions of the wire electrodes do not contact each other during the deposition operation. The bridge droplet is transferred to the molten puddle during a short circuit event between the molten puddle and the wire electrodes.

摘要： A gas tungsten arc welding torch includes a handle and a nozzle located distal of the handle and having a central bore. First and second tungsten electrodes are located partially within the central bore of the nozzle. The torch includes at least one filler wire channel that terminates radially inward of the first tungsten electrode and the second tungsten electrode. The torch includes a torch trigger. Operation of the torch trigger controls delivery of a first filler wire and a second filler wire through the at least one filler wire channel. The torch includes a wire feed speed control. Operation of the wire feed speed control adjusts a wire feed speed of both of the first filler wire and the second filler wire.

摘要： A processing head assembly is disclosed. In some examples, the processing head assembly comprises a fabrication energy source; a wire feedstock surrounded by a shield and one or more filler feedstocks surrounded by one or more nozzles. In some examples, the fabrication energy source includes the wire feedstock surrounded by the shield. A method of depositing material on a substrate using a processing head assembly for use with a fabrication energy source; a wire feedstock surrounded by a shield and one or more filler feedstocks surrounded by one or more nozzles is disclosed. In some examples, the method comprises projecting a fabrication energy beam from the fabrication energy source onto the substrate at a spot, projecting the wire feedstock surrounded by the shield onto the substrate at the spot and projecting the one or more filler feedstocks surrounded by the one or more nozzles onto the substrate close to the spot.

摘要： An apparatus and system for preheating and removing surface oxidation of welding wire using electric arcs one via one or more tungsten electrodes is disclosed. The preheating and cleaning electric arcs may occur between tungsten electrodes, or between one or more tungsten electrodes and welding wire. Electric arc preheating of welding wire allows increased efficiency and deposition rates.

摘要： A welding rod dispenser comprising: a deck, where the deck angles downward from back to front; a rotating assembly located at the front of the deck, where the rotating assembly comprises grabber teeth; and a leveler assembly located atop the deck. Welding rods placed atop the deck may tend to slide forward under the leveler assembly where the leveler assembly levels them into a single layer. Individual welding rods may then be grabbed by the grabber teeth one at a time before being moved forward by the rotating assembly for retrieval by the user.
