Induction brazing is the process of joining two or more metals using induction heating. Induction heating utilizes the electromagnetic field to provide heat without contact or flame. Induction brazing is more localized, repeatable, and easier to automate compared to traditional torch brazing.
Induction brazing has been around for a long time but is only now coming into wider use due to advancements in induction heating power supplies.
The principle of induction brazing is similar to the transformer principle, where the inductor is the primary winding and the part to be heated acts as a single turn secondary winding.
