I'm not sure about welding, but inductive heating doesn't necessarily rely on resonance. A inductive heater is basically a high power transformer primary. The stuff being heated is conductive, so becomes a single-turn secondary. Resonance is not necessary, and will take some tweaking to achieve since the load characteristics can vary. | |
