Induction Brazing Steel To Carbide Plate

Induction Brazing Steel To Carbide Plate

Objective Brazing a steel piston valve assembly
Material Steel piston valve 4.5” dia (11.43cm), tungsten carbide plate and braze
Temperature 1350 ºF
Frequency 100 kHz
Equipment •DW-UHF-40kW induction heating system, equipped with a remote workhead containing six 1.0μF capacitors for a total of 1.5μF
• An induction heating coil designed and developed specifically for this application.
Process A five turn pancake coil is used to braze the piston valve and tungsten carbide plate. The assembly was heated for 10 minutes to flow the braze and join the two pieces.
Results/Benefits Induction heating provides:
• Rapid localized heat, which can minimize oxidation and reduce cleaning after joining
• Hands-free heating that involves no operator skill for manufacturing
• Clean and controllable joints
• Produces high quality repeatable parts

Brazing Carbide To Steel Shank

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)
Frequency: 300kHz
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
