Induction brazing steel to copper

Induction brazing steel to copper

The goal is to braze steel tube to copper tube in 60 seconds using flux and braze alloy.

Equipment
UltraFlex UPT-W15/150
HS-8 Heat Station
Three turns dual diameter coil

Materials

  • Steel tube and copper receiver
  • Braze alloy (CDA 681)
  • B-1 Flux

Key Parameters
Temperature: Approximately 1750°F (954°C)

Frequency
148 kHz

Process:

1. The assembly section was pre-assembled and fluxed (B-1) then located in the two diameter coil with a single pre-formed alloy ring set at the interface area.
2. Alloy flow and joint completed in 60 seconds.
3. The material was cooled in water following the completion of brazing.
4. The joint was then cross-sectioned to validate that the brazing process had produced a strong, high quality joint.

Results/Benefits:

  • Strong durable joints
  • Selective and precise heat zone, resulting in less part distortion and joint stress than welding
  • Less oxidation
  • Faster heating cycles
  • More consistent results and suitability for large volume production, without the need for batch processing
  • Safer than flame brazing
