Induction Soldering Brass Assembly With High Frequency Soldering Units
Objective: To heat a brass bellows and end cap assembly to 4500F for soldering withinĀ 20 seconds. Presently, a soldering iron is used to produce the joint betweenĀ the bellows and cap. The customer requests a quality solder joint with minimalĀ heating of the bellows to prevent annealing and performance losses. SolderĀ preforms, in the form of flat washers, are to be used to complete this application.
Material: Brass Bellows measuring 2″ in diameterĀ Solder Preforms
Cadmium Free Flux
Temperature: 4500F
Application: The DW-UHF-20kW output solid state induction power supplyĀ along with a unique three (3) turn double wound helical coil was utilized toĀ achieve the following results:
4500F was reached and solder flow completed in 6.3 seconds.
A quality repeatable solder joint was observed.
Equipment: DW-UHF-20kW output solid state induction power supply includingĀ one (1) remote heat station containing one (1) 1.2 Ī¼F capacitor, and a uniqueĀ three (3) turn double wound helical coil with an inside diameter of 0.4″.
Frequency: 307 kHz
