Induction Brazing Steel to Wolfram Carbide
Materials
• steel tool tail and wolfram carbide receiver
• Silver soldering paste (PN:R0113)
• Flux
Key Parameters
Temperature: Approximately 780C
Frequency
800 kHz
Process:
1. Mounting tool tail into the carbide work piece hole.
2. Placing brazing paste around the tool tail close to carbide piece.
3. Placing additional flux over the brazing paste.
4. Placing the set into inductor.
5. Alloy flow and joint completed in 5 seconds.
6. The material was cooled in water following the completion of brazing.
7. 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
