Brazing Carbide Tips To Steel With Induction

Brazing Carbide Tips To Steel With Induction Heater Objective: Braze a carbide tip to a 4140 steel cutting tool Material: Carbide Isograde C2 & C5 tips, 4140 circular steel cutter, flux and silver braze shim Temperature 1400 ºF (760 ºC) Frequency 250 kHz Equipment • DW-UHF-20 kW induction heating system, equipped with a remote workhead containing two 1.5μF capacitors for a total of 0.75μF • An induction heating coil designed and developed specifically for this application. Process A split helical coil is used to heat the carbide & circular steel cutter evenly for the brazing application. The circular steel cutter is placed in a vise and the carbide and braze shim are placed onto the tooth. The assembly is heated for 5 seconds to braze the carbide to the circular steel cutter. The circular steel cutter is rotated in the vise & each carbide tip is brazed separately without effecting the previous braze. Results/Benefits Induction heating provides: • Rapid, localized heat applied only to tip being brazed, will not effect previous brazes on the assembly • Neat and clean joints • Produces high quality repeatable parts https://dw-inductionheater.com/brazing-carbide-tips.html?feed_id=250031&_unique_id=666e03d1d84ab
