Brazing Carbide to Steel Part With Induction Heating

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:
  1. 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.
  2. The custom made coil was then placed over the steel piece, where is was set for 14 seconds to heat the alloy.
  3. The alloy was heated at approximately 1500°F (815)°C
  4.  The whole piece is left alone and cooled with ambient air
Results/Benefits:
  • Brazing was successful all in under 20 seconds with 2-kW
  • High quality and repeatability of the brazed joints
  • Increased productivity
  • Rings will need to be developed for specific joints to prevent the use of too much alloy
  • Precise control of the time and temperature
