Brazing Carbide-Steel Tool with Induction

Brazing Carbide-Steel Tool with Induction Objective: Provide a solution to this steel-carbide brazing application Material • Body 10mm; carbide tip 57 x 35 x 3 mm • Braze shim • Braze flux white Temperature: 750°C (1382ºF) Frequency: 150 kHz Equipment DW-UHF-20KW induction heating system, equipped with a remote heat station containing (2) 1.0 μF capacitors (for a total of 0.5 μF) A 4.5" helical induction heating coil designed and developed specifically for this application. Process: The body shim and carbide are cleaned and braze flux as applied to the entire surface of the assembly. The parts are placed together in the induction coil. Two ceramic tubes are then placed thru the coil opposing each other to hold the parts during heating. The flux on the parts is allowed to dry before heating. The induction heating power is applied until the braze flows in the joint. Results/Benefits • targeted heating of the braze joint is efficient • flameless process is more precise, controllable • results are reproducible
