Brazing Silver To Copper With Inductionย
Objective: Heat silver contacts and brass/copper bus for brazingย application
Material: Silver contact .75 (19mm) diameter, brass and copper bus 2โ xย 1โ (50.8 x 25.4mm), braze shims, white flux
Temperature 1300 ยบF (704 ยบC)
Frequency 300 kHz
Equipment โข DW-UHF-10kW induction heating system, equipped with aย remote workhead containing two 1.0ฮผF capacitors for aย total of 0.5 ฮผF
โข An induction heating coil designed and developedย specifically for this application.
Process A five turn split helical coil is used to heat the assembly. Theย parts are placed 90ยบ to the coil between the top turn andย second turn with braze shims and flux. The parts reach 1300ยบF (704 ยบC) in less than 40 seconds to braze the partsย together.
Results/Benefits Induction heating provides:
โข Hands-free heating that involves no operator skill forย manufacturing
โข Better joint quality
โข Faster heating cycles, more consistent results
โข Even distribution of heating
