REDUCED-DISTORTION HYBRID INDUCTION HEATING/WELDING ASSEMBLY

摘要

Inductive heating is added to a metal working process, such as a welding process, by an induction heating head. The induction heating head is adapted specifically for this purpose, and includes one or more coils 36 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 50, 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.
