Demonstrating forge welding in my U.S. Solid 15kW Induction Forge. Forge welding in this system is so easy it feels like cheating. The type of weld demonstrated here is a traditional "drop tong weld", however, as demonstrated, one can simply wiggle the two pieces together well enough in the coil that they stick and you don't need to actually drop the tongs.
Cheers!
