Induction Brazing Copper Tube

Objective To braze a copper tube ( 3/8″ OD by 2-4″ long) into a 3/8″
fitting in less than 10 seconds. Heating must take place in a
channel type coil to allow for easy loading of parts.
Material Copper Tubing and Fitting with Braze and Stay Silv White Flux
Temperature 1300°F
Frequency 105 kHz
Equipment Power of 10 kW output solid state induction power supply equipped with a standard heat station containing eight 0.33 μF capacitors for a total of 0.66μF, a step down transformer, and a specifically designed induction heating coil.
Process Power of 10 kW solid state induction power supply was setup to achieve the following results:
· 2.0 kW of power was directly loaded into the copper tube resulting in a heating time of 7.2 seconds to reach the
necessary 13000F for brazing.
Results Processing ease was achieved through the design of a unique channel type coil comprised of three turns of 1/8″ copper
