Objective
High frequency induction brazing aluminum pipes
Equipment
DW-UHF-6kw-III handheld induction brazing machine
Materials
Аluminum to aluminum tube
Flared at interface 0.25” (6.35mm)
Brazed to steel tube 0.19” OD (4.82mm)
Power: 4 kW
Temperature: 1600°F (871°C)
Time: 5 sec
Temperature: 1600°F (871°C)
Time: 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
