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. https://dw-inductionheater.com/brazing-carbide-to-steel-with-induction.html?feed_id=230166&_unique_id=65465eee1c0f6
