Induction Soldering Brass Bellows Assembly

Objective: To heat a brass bellows and end cap assembly to 450°F for soldering within 20 seconds. 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.
Material: Brass Bellows measuring 2″ in diameter
Solder Preforms
Cadmium Free Flux
Temperature: 450°F
Application: The Power of 10KW,10kW output solid state induction power supply along with a unique three (3) turn double wound helical coil was utilized to achieve the following results:
