induction brazing of copper tubing and brass fitting

Objective
Induction Brazing Copper to Brass fitting using brazing alloy and flux within 60 seconds.

Equipment
UltraFlex UPT-S5 Ultraheat 5 kW
UltraFlex HS-4 Heat Station
2 Turn Helical Coil

Materials
• Brass Fitting
• Copper Tubing
• Silver Brazing Alloy (pre-formed)
• Flux

Key Parameters
Temperature: Approximately 1350 °F (732°C)
Frequency: 188 kHz

Process:

  1. For Induction Brazing Copper to Brass, first the copper tubing and brass fitting were assembled together.
  2. A pre-form of the silver brazing alloy was seated above the joint, and flux was added.
  3. The assembly was placed the two-turn helical coil, and positioned so the targeted joint
    was centered in the coil.
  4. After 60 seconds in the coil, the brazing was complete.
  5. The material was cooled in water following the completion of brazing.
  6. The joint was then cross-sectioned to validate that the brazing process had produced a strong, high quality joint.

Results/Benefits:
Induction heating provides:

  • 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
