Brazing Silver To Copper With InductionĀ
Objective: Heat silver contacts and brass/copper bus for brazingĀ application
Material: Silver contact .75 (19mm) diameter, brass and copper bus 2ā xĀ 1ā (50.8 x 25.4mm), braze shims, white flux
Temperature 1300 ĀŗF (704 ĀŗC)
Frequency 300 kHz
Equipment ā¢ DW-UHF-10kW induction heating system, equipped with aĀ remote workhead containing two 1.0Ī¼F capacitors for aĀ total of 0.5 Ī¼F
ā¢ An induction heating coil designed and developedĀ specifically for this application.
Process A five turn split helical coil is used to heat the assembly. TheĀ parts are placed 90Āŗ to the coil between the top turn andĀ second turn with braze shims and flux. The parts reach 1300ĀŗF (704 ĀŗC) in less than 40 seconds to braze the partsĀ together.
Results/Benefits Induction heating provides:
ā¢ Hands-free heating that involves no operator skill forĀ manufacturing
ā¢ Better joint quality
ā¢ Faster heating cycles, more consistent results
ā¢ Even distribution of heating
