I've been reading hither & yon about industrial uses for induction heating, as applied to welding -
silver-brazing a piece of Carbide tooling to a lesser steel substrate... Since I absolutely suck at torch-brazing...
Most articles recommend a higher frequency... I have the parts, etc, to do a bare-bones hookup through a transformer, directly to the working coil... which will presumably hopefully, do the deed at 60 Hz.
I understand from reading, the higher frequency, will heat the surface to a depth of say... 1/8 inch of a given workpiece... a 1" dia. length of Hot-drawn steel, for the purpose of case-hardening, conversely, straight-up 60 Hz would heat it clear to the core, which is what I need for bending large [ 1" steel ] stock...
Any ideas... I am wanting to proceed with cautious experimentation, as I have some nondescript junky transformers, and other parts that I don't care if I burn them up just for oservation sake...
