Induction brazing aluminum pipes

Objective

High frequency induction brazing aluminum pipes

Equipment
DW-UHF-6kw-III handheld induction brazing machine

Materials
ะluminum to aluminum tube
Flared at interface 0.25โ€ (6.35mm)
Brazed to steel tube 0.19โ€ OD (4.82mm)

Power:ย 4 kW
Temperature:ย 1600ยฐF (871ยฐC)
Time:ย 5 sec

Results and Conclusions:

Induction heating provides:

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