A client came to THE LAB at Ambrell needing to braze a joint between a copper lug and nickel-plated copper pins on a pressurized heater connector. The target temperature was 1175-1375 ºF (635-746 ºC). THE LAB determined that an Ambrell EASYHEATTM 10 kW, 150-400 kHz induction heating power supply would meet the client's objectives.
A two-turn helical coil was designed to heat the copper lugs and nickel-plated copper pins for one minute, which was the client's goal. A clamp was used in production to hold the copper lugs in place for brazing. Induction offered a number of benefits for this brazing application including:
- Minimal transfer of heat to the adjacent ceramic insulator
- Hands-free heating that involves minimal operator skill for manufacturing
• Flameless processing
• Can heat very small precise areas within production tolerances
• Even distribution of heating
