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.

A method for supplying energy to a scrap metal pile (9) in an electric arc furnace (2). Energy is supplied by jets of hot gas in a first phase. Energy is supplied by electric arcs in a second phase after the first phase is completed. Hot gas is supplied via at least six jets. A device (1) for the method has an electric arc furnace (2), one or more blowing devices (6a, 6b, 6c), supply jets of reactant hot air into the chamber (7) of the electric arc furnace (8). The devices have a total of at least six nozzles (10a, 10b, 10c, 10d, 10e, 10f) with nozzle openings. Fuel conducting devices (8) supply fuel to the jets of reactant hot air.
