    摘要： Example welding system comprise: a welding torch comprising a non-consumable electrode configured to establish an arc between the non-consumable electrode and a workpiece; a wire feeder coupled to the welding torch and configured to direct a welding wire toward the workpiece at a location of the arc; and control circuitry configured to control at least one of a current to the arc, a wire feed speed of the welding wire, or preheat energy applied to the welding wire, to deliver the welding wire to the workpiece such that the welding wire applies a physical force to the workpiece prior to melting to push the welding torch along the workpiece.

    摘要： Systems and methods are provided for utilizing wearable wire feeders. An example welding-type system may include a wire feeder device (12)configured for operation in conjunction with a welding-type power supply unit and a welding-type torch (30), with the wire feeder device being a physically separate component from both of the welding-type power supply unit and the welding-type torch, and with the wire feeder device including, at least, a wire source configured to provide electrode wire, and a wire feeding mechanism configured to feed the electrode wire from the wire source. The wire feeder device (12) may be powered by the welding-type power supply unit, and the wire feeder device may be configured to feed the electrode wire to the welding-type torch.

    摘要： A hydrophilic film forming composition is provided that includes a hydrophilic polymer based microemulsion. A surface tension reducing substance is also present. Water is provided as a solvent in which the microemulsion and the surface tension reducing substance are dissolved.
    A hydrophilic film forming composition is also provided that includes a hydrophilic polymer based microemulsion present in an amount of 5 to 45 total weight percent of the composition, and a surface tension reducing substance present in an amount of 5 to 15 total weight percent of the composition. An optional additive of at least one of a wetting agent, a dye, a bitterant, a defoamer, a light stabilizer, and a corrosion inhibitor may be present. The remainder of the composition is water. A process for applying a hydrophilic film to a substrate is also provided.
