Brazing Copper to Brass Pipe With Induction

Brazing Copper to Brass Pipe With Induction

Objective: Brazing several brass and copper assemblies used in water faucets Material braze, white flux

Temperature 1350 °F 730°C

Frequency 200 or 280 kHz (coil dependant)

Equipment DW-UHF-10KW induction heating system, remote work head with two 1μF capacitors and a 3-turn helical coil

Process: Three helical coils are used separately to braze a range of provided parts. Parts are assembled with flux and a braze alloy and then heated. The heat time varies from part to part with large parts taking less than 3 minutes and, the smaller parts heated in less than 20 seconds. After heating the parts are quench-cooled.


Repeatability: the inherent precision of induction heating supports a process which is highly repeatable.

Economy: the process allows for the use of higher temperature braze alloy than a flame process
