Brazing Carbide To Steel Shank with Induction
Objective :Brazing carbide teeth to a steel jaw in less than 5 minutes
Material: Steel pipe jaw, 0.5” (12.7mm) dia, 1.25” (31.75mm) long, 0.25”(6.35mm) thick carbide teeth, black flux and silver copper braze shims
Temperature: 1292ºF (700ºC)
Equipment • DW-UHF-10kW induction heating system, equipped with a remote workhead containing one 0.66μF capacitor
• An induction heating coil designed and developed specifically for this application.
Process: A two turn rectangular helical coil is used to heat the carbide and steel to 1292ºF (700ºC) for 4 to 5 minutes. Three braze 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:
• Hands-free heating that involves no operator skill for manufacturing
• Consistent, repeatable aesthetically pleasing brazes
• Even distribution of heating
