摘要： The present disclosure is directed to systems and methods for pretreating a wire that is used in a welding operation. Using embodiments of the systems and methods disclosed herein, one may remove hydrogen and/or other contaminants from a wire by passing the wire through a pre-treatment chamber, preferably one that isolates the gas discharged from the pre-treatment chamber from the shielding gas utilized in the welding operation; treating the wire within the pre-treatment chamber to release hydrogen and/or other contaminants; and creating a turbulent flow of gas through the pre-treatment chamber. By creating a turbulent flow of gas within the pre-treatment chamber, the transportation of the released hydrogen and/or other contaminants away from the wire may be improved, thereby preventing released contaminants from being reintroduced to the wire or otherwise transported into a weld.

摘要： A harmonic welding wire oscillator configured to oscillate a stretch of welding wire (42) within a wire liner (51). The oscillator may include an actuator (54) configured to oscillate the welding wire (42) at a resonant frequency of the stretch of welding wire. The oscillation causes reciprocation of the welding wire at the tip of the welding torch.

摘要： A welding system configured to eliminate effects of arc blow in a welding operation. The welding system comprises welding circuitry, preheat circuitry, and control circuitry configured to switch the welding circuitry and the preheat circuitry between power levels asynchronously during the welding operation. The control circuitry configured to switch the welding circuitry and the preheat circuitry between power levels asynchronously such that the preheat circuitry is switched to the second preheat power level when the welding circuitry is switched to the first welding power level and the preheat circuitry is switched to the first preheat power level when the welding circuitry is switched to the second welding power level.

摘要： A welding system configured to eliminate effects of arc blow in a welding operation. The welding system comprises welding circuitry, preheat circuitry, a drive roller, and control circuitry configured to perform a reciprocation cycle. The reciprocation cycle may include the steps of: advancing a filler material toward the welding work piece until the filler material is electrically connected to the weld pool; supplying the preheat power to heat the filler material while the filler material is electrically connected to the weld pool; retracting the filler material away from the welding work piece until the filler material is not electrically connected to the weld pool; and terminating supply of the preheat power to the filler material while the filler material is not electrically connected to the weld pool.

摘要： The present disclosure is directed to systems and methods for pretreating a wire that is used in a welding operation to reduce the amount of hydrogen introduced into a weld. Using embodiments of the systems and methods disclosed herein, one passes a wire through a pre-treatment chamber in which a wire is treated to release hydrogen and/or other contaminants, and provides a gas flow through the pre-treatment chamber so that the contaminants that are released from the wire are taken up by the gas. The gas exiting the pre-treatment chamber may be isolated from the shielding gas utilized during a welding operation. For instance, the pretreatment gas may be directed away from the distal end of the welding torch, thereby preventing released contaminants from being transported into a weld.

摘要： the present application relates to an apparatus and to a system (300) for preheating and removing surface oxidation of a welding wire using electric arcs (322, 324, 326) via three or more tungsten electrodes (302, 304, 306) connected to a polyphaser preheating power source (308). Electric arc preheating of welding wire allows increased efficiency and deposition rates.
