Induction Brazing Carbide Onto Steel Part
Objective
Brazing carbide onto steel workpiece
Equipment
DW-UHF-6KW-III Handheld Induction Brazing Heater
Key Parameters
Power: 4kW
Temperature: Approximately 1500°F (815°C)
Time: 16 sec
Materials
Coil-
2 helical turns (20 mm ID)
1 planar turn (40 mm OD, 13 mm Height)
Carbide-
13 mm OD, 3 mm wall thickness
Steel piece–
20 mm OD, 13 mm ID
Process:
- To demonstrate elimination of “hand feeding” the alloy, we formed the alloy into a ring to tightly fit over the center post tube. This method provides a uniform amount for each cycle, resulting in uniform joints and wetting.
- The custom made coil was then placed over the steel piece, where is was set for 14 seconds to heat the alloy.
- The alloy was heated at approximately 1500°F (815)°C
- The whole piece is left alone and cooled with ambient air
