Systems and methods are described to address issues associated with welding with cored wires. In certain processes, a welding wire may "stick" or fuse to a contact tip. To mitigate the negative effects of a wire fusing to a contact tip, a double pulse waveform is applied.

In examples, the second current level is sufficient to dislodge a spot weld between the welding wire and the welding torch yet insufficient to transfer a ball of molten welding wire.
Described herein are examples of smart welding helmets having a plurality of functions that go beyond conventional welding helmets. For example, a smart welding helmet may be configured to detect if/when the helmet surpasses one or more temperature thresholds, which may alert an operator if they have been welding too close and/or for too long. Other example smart helmet functions may include the ability to display (and/or otherwise output) feedback/guidance and/or welding information, as well as communicate with appropriate personnel. In some examples, the smart welding helmet may be configured to selectively enable/disable certain functions of the smart welding helmet to accommodate the needs of a particular operator and/or groups of operators.
An example welding-type system includes: power conversion circuitry configured to convert input power to welding-type power; an interface configured to: receive a selection of a parameter from a plurality of parameters; and receive a selection of a value for the selected parameter; and control circuitry configured to: in response to the selection of the parameter from the plurality of parameters, control the interface to output a visual indication of an effect of changing the parameter on at least one of a welding electrode, a quantity of discontinuities in the weld, a magnitude of a discontinuity in the weld, or a quantity of inclusions in the weld; in response to a change in the value of the selected parameter via the interface, control the interface to change the visual indication of the effect based on the change in the value; and control the power conversion circuitry based on the value.
Described herein are examples of torch tracking systems that monitor travel directions, speeds, and/or distances of welding torches using retractable cords. In some examples, the torch tracking systems use a sensor to measure a speed at which a reel extends and/or retracts a cord, and/or measure a length of the cord that is extended and/or retracted. The reel or cord can be attached to some portion of the welding torch, such that movement of the torch away from the reel causes the reel to extend more cord, and movement towards the reel allows a spring loaded spool of the reel to automatically retract the cord. While reel based torch tracking systems may provide coarser tracking than the more complex and/or expensive torch tracking solutions, their simplicity and low cost may make them an attractive alternative.
Disclosed are systems and methods for feeding welding wire for welding-type applications. The wire-feeder system comprises a base platform, a spool hub, a drive roll assembly, and a wire guide assembly. The spool hub can be mounted to the base platform perpendicular to the base platform and configured to support a wire spool. The drive roll assembly can be mounted to the base platform, and having one or more sets of drive rollers configured to feed wire from the wire spool toward a welding torch. The wire guide assembly can be mounted to the base platform separately from both the wire spool and the drive roll assembly.
Systems and methods for setting the polarity of welding-type power provided by a welding- type power supply. The output polarity may be automatically selected based on one or more selectable welding parameters. The automatically selected polarity may be overridden based on operator input.
Systems and methods are described to address issues associated with welding with cored wires. In certain processes, a welding wire may "stick" or fuse to a contact tip, such as at termination of a weld. To mitigate the negative effects of a wire fusing to a contact tip, the wire remains in motion at a time prior to the end of the weld, as the weld ends, and/or for a time after the end of the weld, to limit and/or eliminate fusion between the wire and the contact tip.
A method of repairing a surface defect (D) with a patch (10) is provided. A fibrous substrate (12) is impregnated with a formulation (14) that includes a polyester resin, a crosslinking agent, a solvent, and a particulate filler. The fibrous substrate is contacted with the surface defect. The formulation is exposed to actinic radiation to induce cure of the formulation to form the patch to repair the surface defect. A kit is also provided that includes a bottle (22) containing the formulation. A sheet of fibrous support material is also provided that is adapted to receive the formulation therethrough. Instructions (28) for repairing a surface defect by the aforementioned method are also provided as part of the kit. 3D printing of an article to fit in the surface defect is also disclosed.

ULTRA-FAST UV-CURED MATERIAL FOR REPAIRING SURFACE IMPERFECTIONS
A method of sealing surface imperfections on a sanded surface of a repair to a vehicle body is provided that includes an uncured layer of a formulation being applied to sanded cured body filler on the vehicle body. The formulation includes a polyester resin, a crosslinking agent, a solvent, and a particulate filler. The uncured layer is exposed to actinic radiation to induce cure of the uncured layer to form a sealing coating. The resulting seal coating has able to seal surface imperfections. A surface imperfection sealing formulation is also provided that includes a polyester resin and a multifunctional crosslinking agent. A solvent is provided. A photoinitiator renders the formulation curable upon exposure to ultraviolet light exposure. A particulate filler is also present in an amount to result in a formulation with an uncured viscosity of between 2600 and 3000 centipoises.
