Brazing Carbide to Steel Part With Induction Heating
Objective Brazing carbide to steel part Equipment DW-UHF-6kw Induction Heating Power Supply ultra high frequency custom coil Key Parameters Power: 1.88 kW Temperature: Approximately 1500°F (815°C) Time: 14 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
Induction Brazing 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
