Induction Brazing of Copper Tube to Copper Bracket

Objective:

  We design the coil like below to braze the copper tube to the copper bracket, the brazing copper tube diameter is 50mm, thickness is 3-5mm, and the copper plate or copper bracket thickness is 20mm. Our purpose is to braze the tube and bracket together with induction heating solutions.

Key Parameters:

Power: 50 kW

Temperature: Approximately 1400° F (760° C)

Time: 50 sec to let them all brazed together

Process:

  • The key point is to do the right induction brazing tool, we use open mouth type induction coils like the attached picture.
  • With induction heating to do the brazing job until the brazing flux is total uniform melt.
  • After brazing, check the brazing seal is very uniform and good connections.

Result and benefits:

  • Induction brazing is faster than flame brazing and do not have high requests for the brazing workers, and also good for environment.
  • We design the suitable induction brazing coils to ensure the bottom and the brazing bracket can be heated uniform.
  • We use medium frequency induction heating machine to heat this job to ensure the heating depth much better.
  • The heating time is faster and also energy-saving a lot.
  • When arrives user site, coils also need a fixture to let the workpiece well placed into the coil for better brazing.
