  • Patent number: 11172549
    Abstract: In certain embodiments, inductive heating is added to a metal working process, such as a welding process, by an induction heating head. The induction heating head may be adapted specifically for this purpose, and may include one or more coils to direct and place the inductive energy, protective structures, and so forth. Productivity of a welding process may be improved by the application of heat from the induction heating head. The heating is in addition to heat from a welding arc, and may facilitate application of welding wire electrode materials into narrow grooves and gaps, as well as make the processes more amenable to the use of certain compositions of welding wire, shielding gasses, flux materials, and so forth. In addition, distortion and stresses are reduced by the application of the induction heating energy in addition to the welding arc source.

  • Patent number: 11014185
    Abstract: Apparatus, systems, and/or methods for weld wire preheating are disclosed. Some examples of the present disclosure relate to welding-type systems that use one or more preheaters to heat welding wire prior to an arc and/or deposition on a weldment. The welding wire may have one or more characteristics. A preheating control may determine a governing characteristic of the one or more welding wire characteristics and establish a threshold temperature and/or target temperature based on the governing characteristic. The preheating control may further control the one or more preheaters based on the threshold temperature and/or target temperature, in order to avoid a deformation and/or degradation of the welding wire that would impact column strength, wire feeding, weld process stability, and/or welding consumable longevity.

  • Patent number: 10661372
    Abstract: A system and method for determining settings or parameters for a welding-type power source are provided. By presenting an operator with an interface that is positioned along the path of a weld cable and configured to input weld characteristics, an operator is not required to determine electrical parameters for setting a welding-type power source output at the power source. The interface is presented to the operator at a remote welding-type device, such as a wire feeder, a weld robot, a torch, or the like. From the operator-specified weld characteristics, the system and method determine appropriate settings for the power source. In some embodiments, the system and method may automatically set the power source accordingly.
