Results and Conclusions:
Induction heating provides:
![](https://dw-inductionheater.com/wp-content/uploads/2020/05/induction-brazing-aluminum-tubing-2-1024x702.png)
- 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
