Note: Brazing an aluminum bicycle assembly
Objective:
Braze an aluminum assembly to 968 °F (520 °C) within 20 seconds
End Product:
Bicycle tube
Equipment:
Ambrell EKOHEAT 20/10 LI, 20kW 5-15 kHz induction heating system equipped with a remote heat station containing one 53 μF capacitor A two-position helical induction heating coil designed and developed specifically for this application
Materials:
Customer supplied 1.33 in (33.8 mm) O.D. aluminum tube and aluminum mating part Aluminum braze alloy
Temperature:
968 °F (520 °C)
Frequency:
10 kHz
Testing:
Braze material was applied between the tubing and the mating part. The assembly was placed inside the coil and heated for approximately 40 seconds. With a two-position coil, two parts can be heated simultaneously, which means one part would be completed every 15-20 seconds. Braze material was stick fed, which created a good joint. The heating time with two parts being heated simultaneously meets the client's objective, and represents a significant improvement in regards to speed over using a torch.
Benefits:
-
Speed: The recommended approach cut their heating time in half when compared to using a torch
-
Part quality: Induction heating is a repeatable method with more consistency than a torch can generally deliver
-
Safety: Induction heating is a clean, precise method that does not involve an open flame like a torch, which results in a safer work environment
-
Free lab testing: Ambrell"s Lab Service Request testing enabled the client to test their application to ensure induction heating would meet their desired heating time
