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

Brazing Carbide-Steel Tool with Induction

Brazing Carbide-Steel Tool with Induction

Objective: Provide a solution to this steel-carbide brazing application Material • Body 10mm; carbide tip 57 x 35 x 3 mm • Braze shim • Braze flux white

Temperature: 750°C (1382ºF)

Frequency: 150 kHz

Equipment DW-UHF-20KW induction heating system, equipped with a remote heat station containing (2) 1.0 μF capacitors (for a total of 0.5 μF) A 4.5″ helical induction heating coil designed and developed specifically for this application.

Process: The body shim and carbide are cleaned and braze flux as applied to the entire surface of the assembly. The parts are placed together in the induction coil. Two ceramic tubes are then placed thru the coil opposing each other to hold the parts during heating. The flux on the parts is allowed to dry before heating. The induction heating power is applied until the braze flows in the joint.

Results/Benefits

• targeted heating of the braze joint is efficient

• flameless process is more precise, controllable

• results are reproducible

Brazing Carbide To Steel With Induction

Brazing Carbide To Steel With Induction 

Objective: Braze carbide rotary file assemblies with uniform concentricity in an aerospace application

Material :

• Carbide blank

• High speed steel shank

• Temperature indicating paint

• Braze shim and black flux

Temperature 1400°F (760°C)

Frequency 252 kHz

Equipment DW-UHF-10kw induction heating system, equipped with a remote heat station containing two 0.33 μF capacitors (total 0.66 μF) An induction heating coil designed and developed specifically for this application.

Process A multi-turn helical coil is used. The part is heated to determine the time required to reach the desired temperature and required heat pattern. It takes approximately 30 – 45 seconds to reach 1400°F (760°C) depending on the various part sizes. Flux is applied to the entire part. A braze shim is sandwiched between the steel shank and carbide. Induction heating power is applied until the braze flows. With proper fixturing, concentricity of the part can be achieved.

Results/Benefits • Repeatable, consistent precise heat.
