Note: Brazing steel tube fittings
Objective:
Braze.75 in (19mm) tube fittings together, which are magnetic steel assembly components. The client was interested in upgrading from a 2.5 kW system as they need to process larger parts.
End Product:
Steel tubes
Equipment:
Ambrell EASYHEAT 5060, 5.0 kW induction heating system, equipped with a remote workhead containing one 1.0Ä μF capacitor. A helical induction heating coil designed and developed specifically for this application
Materials:
Two magnetic steel components Black flux Braze rings
Temperature:
1400 °F (700 °C)
Frequency:
200 kHz
Testing:
A braze ring was applied, and the steel tubes were put together. The multi-turn helical coil was adjusted to be level with the tubes. The assembly was heated to the desired braze temperature in 20-25 seconds, which achieved the client's targeted cycle time of less than 30 seconds.
Benefits:
-
Braze temperature was reached quickly which saves time and energy when compared to other heating methods
-
Direct and precise control of heat also saves energy compared to other heating methods
-
The 5.0 kW unit enabled this client to braze larger components within the targeted cycle time
-
The braze alloy forms a good joint, validating the high quality level that can be achieved via induction
-
Can easily be integrated into an automated process
