About Induction Brazing

Induction Brazing is a process for joining similar or dissimilar metals using a filler metal using the precision heating of an RF induction heating unit. The filler metal is heated slightly above its melting point so it flows, but the temperature remains lower than than the melting points of the base metals it is joining. Flux or an inert atmosphere can be used to protect the two metal surfaces being joined and the brazing material from oxidation during the heating process. The filler material melts flows over the base metals, and the entire assembly is then cooled to join the pieces together.

While brazing is a similar process to soldering, the temperatures needed to melt the filler metal are higher for brazing, with temperatures typically 900ºF – 2200ºF (470ºC – 1190ºC). Brazing differs from welding in that brazing does not melt the base metals, therefore brazing temperatures are lower than the melting points of the base metals. For this reason, brazing is a superior choice in joining dissimilar metals, as it results in less part distortion and joint stress, while resulting in a strong joint. Typical braze filler materials are copper, silver, zinc, nickel and aluminum. Typical joined materials are: steel-to-copper, steel-to-brass, and brass-to-copper. A properly-made brazed joint will typically be as strong or stronger than the base metals being joined.

Brazing is commonly used for any manufacturing process that joins two metal pieces. Benefits of Induction Brazing include: Ability to join similar and dissimilar metals; less part distortion and joint stress than welding; strong, durable joints; selective heating and better joint quality; reduced oxidation and the need for acid cleaning; faster heating cycles; more consistent results and suitability for large volume production; and improved safety versus flame brazing.
