Induction Brazing Copper Assemblies
Objective A company had been using a flame for brazing copper assemblies to make electrical components, but they contacted THE LAB at Ambrell because...
Objective
A client needed to heat copper and nickel parts prior to bending. The target temperature for the application was 1,500-1,800 °F (816-982 °C).

Evaluation
A specially designed multiple-turn helical coil was used to provide heat to the parts. Initial tests were conducted to optimize the power delivered to the parts and to understand the heating patterns. After significant testing on the coil setup to optimize the process, heating times of 10 seconds were achieved. A ceramic or non-conducting tube was used to isolate the parts from the coil.
Solution
THE LAB at Ambrell proved the viability of this preheating application. An Ambrell EKOHEAT 30 kW/50-150 kHz induction heating power supply was used for the application with frequency set at 81 kHz.
THE LAB at Ambrell has considerable experience with heating prior to bending applications, which enabled them to deliver a solution that met the client's requirements. To learn more about free application testing, visit our page about THE LAB to get the process started.
