Induction brazing aluminum pipes

Objective

High frequency induction brazing aluminum pipes

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

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

Power:Ā 4 kW
Temperature:Ā 1600Ā°F (871Ā°C)
Time:Ā 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
