    Abstract: A composition for welding or brazing aluminum comprises silicon (Si) and magnesium (Mg) along with aluminum in an alloy suitable for use in welding and brazing. The Si content may vary between approximately 4.7 and 10.9 wt %, and the Mg content may vary between approximately 0.20 wt % and 0.50 wt %. The alloy is well suited for operations in which little or no dilution from the base metal affects the Si and/or Mg content of the filler metal. The Si content promotes fluidity and avoids stress concentrations and cracking The Mg content provides enhanced strength. Resulting joints may have a strength at least equal to that of the base metal with little or no dilution (e.g., draw of Mg). The joints may be both heat treated and artificially aged or naturally aged.

    Abstract: Methods and apparatus to communicate via a weld cable are disclosed. An example weld circuit communications device includes a receiver circuit, a processor, and a local communications adapter. The receiver circuit to receive a communication via a weld circuit while current is flowing through the weld circuit or after the current has stopped flowing through the weld circuit, the communication including weld voltage feedback information measured at a device remote from a power supply and remote from the weld circuit communications device while the current is flowing through the weld circuit. The processor generates power supply control information based on the weld voltage feedback information. The local communications adapter transmits the power supply control information to control welding-type power output by a power converter to regulate a weld voltage to a weld voltage setpoint.

    Abstract: A welding system comprises a hand-held weld tool comprises a positioning and orientation measurement system having an inertial measurement unit (IMU), a processing subsystem, and a calibration apparatus. The processing subsystem is operable to compute, based on data generated by the IMU during a weld operation on a workpiece, one or more actual motion attributes for the hand-held weld tool. The calibration apparatus is configured to hold the hand-held weld tool in a known position and orientation and in stationary state for calibration of the positioning and orientation measurement system.

    Abstract: Embodiments described herein include wireless control of a welding power supply via portable electronic devices, such as dedicated original equipment manufacturer (OEM) welding remote devices, cellular radio telephones, satellite radio telephones, laptops computers, tablet computers, and so forth. In particular, operating parameters and statuses of the welding power supply may be modified by the portable electronic device, as well as be displayed on the portable electronic device. A pairing procedure may be used to pair the welding power supply and the portable electronic device in a wireless communication network. Furthermore, in certain embodiments, a method of providing location services for the welding power supply includes utilizing location data for the portable electronic device controlling the welding power supply as an approximation for the location of the welding power supply.

    Abstract: A contact tip assembly with a preheating tip comprises a welding-type power source configured to provide welding-type current to a welding-type circuit, the welding-type circuit comprising a welding-type electrode and a first contact tip of a welding torch; an electrode preheating circuit configured to provide preheating current through a first portion of the electrode via a second contact tip of the welding torch; and a preheat controller to: monitor a voltage drop across a second portion of the electrode; adjust at least one of the welding-type current or the preheating current based on the voltage drop, the second portion of the electrode comprising at least part of the first portion of the electrode; and control the preheating current based on a hydrogen reduction goal and based on stored parameters associated with a type of the electrode, a chemistry of the electrode, or a wire size.

    Abstract: Sensor assisted head mounted displays for welding are disclosed. Disclosed example head mounted devices include an optical sensor, an augmented reality controller, a graphics processing unit, and a semi-transparent display. The optical sensor collects an image of a weld environment. The augmented reality controller determines a simulated object to be presented in a field of view, a position in the field of view, and a perspective of the simulated object in the field of view. The graphics processing unit renders the simulated object based on the perspective to represent the simulated object being present in the field of view and in the weld environment. The display presents the rendered simulated object within the field of view based on the position. At least a portion of the weld environment is observable through the display and the lens when the display is presenting the rendered simulated object.

    Abstract: Methods and apparatus to communicate via a weld cable are disclosed. An example welding-type power supply includes a power converter, a receiver circuit, and a controller. The power converter converts input power to welding-type power based on a weld voltage setpoint and to output the welding-type power via a weld circuit. The receiver circuit receives a communication via the weld circuit while current is flowing through the weld circuit or after the current has stopped flowing through the weld circuit. The communication includes weld voltage feedback information measured at a device remote from the power supply while the current is flowing through the weld circuit. The controller controls the welding-type power output by the power converter according to a voltage feedback loop using the weld voltage feedback information to regulate a weld voltage at the remote device to the weld voltage setpoint.
