Abstract
This disclosure relates generally to welding, and more specifically, to submerged arc welding (SAW). In an embodiment, a welding system includes a gas supply system configured to provide a gas flow. The system also includes a wire supply system configured to provide welding wire, and a flux supply system configured to provide flux near a welding arc during submerged arc welding (SAW). The system further includes a welding torch assembly configured to receive the gas flow and the welding wire and to deliver the gas flow and the welding wire near the welding arc during SAW.
Claims20
A welding system, comprising:
- a gas supply system configured to provide a gas flow;
- a wire supply system configured to provide welding wire;
- a flux supply system configured to provide flux near a welding arc during submerged arc welding (SAW);
- and
- a welding torch assembly configured to receive the gas flow and the welding wire and to deliver the gas flow and the welding wire near the welding arc during the SAW.
A system, comprising:
- a welding torch assembly, comprising:
- a welding torch body comprising a gas conduit configured to flow one or more gases through the welding torch body;
- a contact tip comprising one or more gas conduits configured to flow the one or more gases near a welding arc, wherein the contact tip is configured to couple to the welding torch body such that the gas conduit of the welding torch body is in fluid communication with the one or more gas conduits of the contact tip;
- and
- a flux delivery component configured to deliver granular flux near the welding arc, wherein the flux delivery component is coupled to the welding torch body near the contact tip and configured to mix the granular flux with the one or more gases.
A method, comprising:
- delivering a gas flow and a flow of granular flux near a progressing submerged arc welding (SAW) weld pool;
- and
- depositing the flow of granular flux over the progressing SAW weld pool to form a flux bed.
