A method of operating a welding system includes receiving welding data corresponding to a welding session for a weld, receiving a location selection from an operator, and displaying on a display a graphical representation of welding parameters of the welding selection corresponding to the location selection. The welding data includes welding parameters, including 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 a path of the weld, an aim of the welding torch, or any combination thereof. The location selection corresponds to a point along the path of the weld traversed by the welding torch.

System and method of monitoring welding information

Welding headwear comprises one or more image sensors, processing circuitry, and a display. The image sensor(s) are operable to capture an image of an unpowered weld torch as the torch passes along a joint of a workpiece to be welded. The processing circuitry is operable to: determine, through processing of pixel data of the image, one or more welding parameters as the torch passes along the joint to be welded; generate, based on the one or more welding parameters, a simulated weld bead; and superimpose on the image, in real time as the torch passes along the joint, the simulated weld bead on the joint. The display is operable to present, in real time as the torch passes along the joint, the image with the simulated bead overlaid on it.

Multiple input welding vision system

An engine-driven welder/generator is controlled by an integrated controller that is coupled to both the engine and to the welder/generator. The controller receives input signals for operational parameters of the engine, and additional signals indicative of electrical output by the welder/generator. Operation of the engine and welder/generator may thus be coordinated. The controller may control speed, timing, fuel injection, and so forth of the engine, and output of the welder/generator, such as by control of input to a field coil.

Integrated engine-driven generator control system

Welding headwear comprises a display operable to present images for viewing by a wearer of the welding headwear, and comprises circuitry operable to determine an identifier associated with a workpiece, retrieve, from memory, welding work instructions associated with the identifier, and generate the images for presentation on the display based on said work instructions.

Augmented vision system with active welder guidance

An example weld training system includes: a weld training device configured to perform a simulated welding procedure on a simulated weld joint; a work surface comprising the simulated weld joint; a sensing device configured to track weld training device location information during the simulated welding procedure; a visual interface configured to display results of the simulated welding procedure based on the weld training device location information; and an enclosure comprising an interior volume configured to house within its interior the visual interface, the work surface, and the sensing device.

Weld training systems and methods

A wire conveying mechanism, preferably for a welding, cladding or additive manufacturing apparatus, with a slip clutch mechanism connectable to a motor. Such a wire conveying mechanism may include a wire feeder for feeding an electrode wire in a welding system having a drive roller assembly comprising a plurality of drive rollers to grip the electrode wire and to pull the electrode wire from an electrode wire source toward a conduit and a torque-managing device operatively coupled between a motor and the drive roller assembly, wherein the torque-managing device receives the rotational force from the first motor and regulates the first torque to output a second torque to the drive roller assembly.

Wire feeder for welding

Weld training systems and methods are disclosed. An example weld training system includes: a weld training device configured to perform a simulated welding procedure on a simulated weld joint; a work surface comprising the simulated weld joint; a sensing device configured to track weld training device location information during the simulated welding procedure; a visual interface configured to display the simulated welding procedure; and an enclosure comprising an interior volume configured to house within its interior the visual interface, the work surface, or the sensing device.

Dynamic range enhancement methods and systems for display for use welding applications are disclosed. An example display system in a dynamic range enhancement system includes: a first filter disposed in a first path; a second filter disposed in a second path, wherein the second filter has a lower density than the first filter, at least one of the first filter or the second filter configured to provide variable lens shading; a first image sensor disposed in the first path and configured to receive filtered electromagnetic waves from the first filter; a second image sensor disposed in the second path and configured to receive filtered electromagnetic waves from the second filter; and a graphical circuit configured to combine signals from the first image sensor and the second image sensor.

Dynamic range enhancement systems and methods for use in welding applications

A method and apparatus provides welding-type power and preferably includes a removable battery or other energy storage device, a converter connected to the battery, and a controller. The controller may have a CV and/or a CSC and/or an AC weld control module, and/or an ac auxiliary control module. The converter is a boost converter, a buck converter, a cuk converter, a forward converter, an inverter, a bridge converter, and/or a resonant converter. The controller may include a battery charging control module, and may have one or more charging schedules, and/or data for stored charge, thermal information, expected life of the battery, maximum amp-hour charge for the battery, maximum charging current and/or feedback. The battery charging schedules may include at least 3 phases, such as a phase of increasing voltage and a phase of decreasing current, a substantially constant power phase. The controller can wirelessly provide data to a display or pda. A generator may provide power to the battery, charger, and/or the weld. It can include a vehicle and use its dc power system.

Method and apparatus for welding with battery power

A welding system including a helmet having one or more sensing devices configured to detect a position and an orientation of a welding torch relative to a workpiece during performance of a welding session, and a controller coupled to the one or more sensing devices and configured to receive arc parameters corresponding to the performance of the welding session.
