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 battery manufacturer needed to heat battery lugs for a burn-off application. They required a 20-second cycle time, so speed along with repeatability were critical to them. The target temperature was 400 °F (204 °C). They contacted THE LAB at Ambrell to design a coil and confirm the viability of their heating application.

Evaluation
A custom-designed multiple-position helical coil was built to generate the required heating for the burn-off application. Initial tests were conducted to optimize the power delivered to the part using an Ambrell EKOHEAT 15 kW, 50-150 kHz induction heating system. Several coils were tested and the one chosen was selected due to its flexibility/versatility.
Solution
The coil design THE LAB chose can be expanded to a 12-position setup for scalability. The solution was able to achieve the customer's cycle time objective. Benefits included speed, repeatability, energy efficiency, safety and a smaller required footprint than some other heating options such as an oven.
