  • Patent number: 12059758
    Abstract: 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.
