Induction Brazing Carbide Steel

Objective
Braze various steel parts to a tungsten carbide plate using induction.

Equipment
UPT W10/150 Power Supply
HS-8 Heat Station

Test 1

Materials
• Steel rod: 19.05 mm (0.75″) OD, 82.55 mm (3.25″) Length

• Tungsten Carbide Plate: 38.1 mm (1.5″) OD, 10.16 mm (0.4″) Thickness

• Alloy: 19.05 mm (0.75″) Brazing discs

Power: 4.0 kW
Temperature: Approximately 760° C (1400° F)
Time: 40 sec

Test 2

Materials
• Steel rod: 12.7 mm (0.50″) OD, 76.2 mm (3″) Length

• Tungsten Carbide Plate: 19.05 mm (0.75″) OD, 6.35 mm (0.25″) Thickness

• Alloy: 12.7 mm (0.50″) Brazing discs

Power: 2.36 kW
Temperature: Approximately 760° C (1400° F)
Time: 23 sec

Test 3

Materials
• Steel rod: 12.7 mm (0.50″) OD, 76.2 mm (3″) Length

• Tungsten Carbide Plate: 1″ OD, 1.39mm (0.055″) Thickness

• Alloy: 12.7 mm (0.50″) Brazing discs

Power: 2.36 kW
Temperature: Approximately 760° C (1400° F)
Time: 20-25 sec (Pulsing on/off)

Test 4

Materials
• Steel rod: 6.35 mm (0.25″) OD, 76.2 mm (3″) Length

• Tungsten Carbide Plate: 21.08mm (0.83″) OD, 1.65mm (0.065″) thicknes

• Alloy: 6.35 mm (0.25″) Brazing discs

Power: 1.96 kW
Temperature: Approximately 760° C (1400° F)
Time: 20 sec (Pulsing on/off)

Results and Conclusions:

Brazing of different steel parts to carbide disks is possible with one induction coil. Power was regulated by turning the heat on and off using a foot switch to prevent overheating of the carbide parts.
