Induction brazing is used in the joining of many different metals for numerous applications. Induction is a superior method of brazing due to its fast, efficient, flameless, non-contact heating. Typical joints are steel-to-steel, steel-to-brass, steel-to-copper, brass-to-copper, brass-to-copper, copper-to-copper, aluminum-to-aluminum, and copper-to-aluminum.
There are six steps to a quality induction brazed joint:
- Design the joint correctly allowing for a 40µm (0.0015”) to 125µm (0.005”) clearance between the two surfaces at the braze material flow temperature – to allow for capillary action and joint wetting.
- Clean the surfaces of the joint materials.
- Apply flux to both pieces. Flux removes oxides from the base material while also preventing oxidation during heating.
- Fixture the two pieces together with a braze ring or pre-form and position in the coil.
- Heat the two pieces until both pieces achieve the braze material flow temperature and stick feed the braze material if pre-forms are not being used. (Our highly experienced applications lab will make sure the coil is designed to correctly heat your parts).
- Clean the brazed joint and remove all of the flux residue.
More information on how induction heating is used in the brazing process is available in our Brazing Guide. We encourage you to read more about our induction brazing solutions in the brochure. You can download it by clicking the button below.
