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: 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: Methods and apparatus to provide visual information associated with welding operations are disclosed. An weld training system includes a display, a camera, a communications device, and a welding helmet. The communications device communicates with welding equipment. The welding helmet has a view port. The communications device is configured to hold the camera, the communications device, and the display such that, when the welding helmet is worn by a wearer, the display is viewable by the wearer, the camera has a view through the view port such that the display displays to the wearer images taken by the camera through the view port and displays a simulated object generated based on information received from the welding equipment via the communications device.

Abstract: Methods and apparatus to determine heat input to a weld are disclosed. An example welding-type power supply includes a power converter to convert input power to output welding-type power, and a controller configured to: during a welding-type operation, calculate average instantaneous power values of the welding-type operation for discrete, non-overlapping time periods by multiplying voltage measurements and corresponding current measurements; identify an end of the welding-type operation; determine a duration of the welding-type operation; calculate a total average instantaneous power of the welding-type operation based on the average instantaneous power values for the time periods and the duration of the welding-type operation; and output a first value representative of the total average instantaneous power and a second value representative of the duration of the welding-type operation.

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 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.
