Brazing Carbide To Steel Shankย with Induction
Objective :Brazing carbide teeth to a steel jaw in less than 5 minutes
Material: Steel pipe jaw, 0.5โ (12.7mm) dia, 1.25โ (31.75mm) long, 0.25โ(6.35mm) thick carbide teeth, black flux and silver copperย braze shims
Temperature: 1292ยบF (700ยบC)
Frequency: 300kHz
Equipment โข DW-UHF-10kW induction heating system, equipped with aย remote workhead containing one 0.66ฮผF capacitor
โข An induction heating coil designed and developedย specifically for this application.
Process: A two turn rectangular helical coil is used to heat the carbideย and steel to 1292ยบF (700ยบC) for 4 to 5 minutes. Three brazeย shims control the amount of braze and the even heat allows for
a good flow of braze creating an aesthetically pleasing bond.
Results/Benefits Induction heating provides:
โข Hands-free heating that involves no operator skill forย manufacturing
โข Consistent, repeatable aesthetically pleasing brazes
โข Even distribution of heating
