6 Steps to a Quality Induction Brazed Joint

Oct 21, 2015 4:23:00 AM / by Justyna Bakker

Induction brazing is used in the joining of many different metals for multiple applications. 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:

  1. 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.
  2. Clean the surfaces of the joint materials.
  3. Apply flux to both pieces. 
  4. Fixture the two pieces together with a braze ring or pre-form and position in the coil.
  5. 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).
  6. Clean the brazed joint and remove all of
     
    the flux residue.
