A heat input control method for a welding system includes the step of receiving data encoding a desired heat input range having heat input values included between an upper limit and a lower limit. The method also includes the step of receiving data encoding a desired change to a level of a first weld variable of a set of weld variables. Further, the method includes determining a change to a level of a second weld variable of the set of weld variables. The determined change to the level of the second weld variable is suitable to maintain a heat input of a welding operation within the desired heat input range.

Heat input control for welding systems

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.

System and method for submerged arc welding

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 fluorine-containing 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 fluorine-containing gas flow and the welding wire and to deliver the fluorine-containing gas flow and the welding wire near the welding arc during the SAW.

Systems and methods for using fluorine-containing gas for submerged arc welding

Embodiments of the present disclosure are also directed to a web-configuration system that includes at least one processor and one or more tangible, machine-readable media at least collectively including or storing instructions executable by the at least one processor. The instructions include a module configured to limit configuration options for a welding system based on user selection of a power source for the welding system, a module configured to calculate a weld cable size for the welding system based on the user selection of the power source and user selection of an input voltage, a module configured to assign weld cable characteristics based on the weld cable size and a user selected cable length, and a module configured to assemble a welding system order based at least on the user selection of the power source and the weld cable characteristics.
