Note: Brazing Threaded Bulkhead Fitting
LSR# 37463
Objective:
Induction is used to braze a collection of customer-supplied copper FNPT fittings to a series of steel plates to 1400 °F (760 °C) to facilitate a water heater bulkhead.
End Product:
water heater bulkhead
Equipment:
Ambrell EASYHEAT 10.0 kW induction heating system, equipped with a remote work head containing (2) 1.0 μF capacitors.
Materials:
A range of customer-supplied copper FNPT fittings and a selection of steel plates
Temperature:
1400 °F (760 °C)
Frequency:
364 kHz
Testing:
A custom-designed multi turn pancake coil was built to generate the required heating for the application. Initial tests were conducted to optimize the power delivered to the part. Once a satisfactory heat pattern was achieved in the time frame allowed, samples were run at multiple different settings.
Heating time with the EH power supply shows that a temperature can be achieved within 90 seconds.
Benefits:
- Consistent and repeatable results
- No flame process
- Faster process time
