Soldering Brass Bellows Assembly

Objective

To heat a brass bellows and end cap assembly to 450 °F for soldering within 20 seconds. 

End Product

Brass Bellows

Equipment

Ambrell 1kW output solid state induction power supply including 1 remote heat station containing one 1.2 µF capacitor, and a unique three-turn double-wound helical coil with an inside diameter of 0.4".

Materials

Brass Bellows measuring 2" in diameter, Solder Preforms, Cadmium-Free Flux

Temperature

450 *F

Frequency

307 kHz

Testing

Presently, a soldering iron is used to produce the joint between the bellows and cap. The customer requests a quality solder joint with minimal heating of the bellows to prevent annealing and performance losses. Solder preforms, in the form of flat washers, are to be used to complete this application.
