Induction Brazing Carbide To Stainless Steel

Induction Brazing Carbide To Stainless Steel Shaft With IGBT Heating Units Objective Brazing a cone shaped carbide to a stainless steel shaft for a digger Material Cone shaped carbide 1.12” (28.4mm) dia, 1.5”(38.1mm) tall, stainless steel shaft 1.12” (28.4mm) dia and various length, black brazing flux and braze shims Temperature 1500 ºF (815 ºC) Frequency 277 kHz Equipment • DW-UHF-10 kW induction heating system, equipped with a remote workhead containing two 1.0μF capacitors for a total of 0.5μF • An induction heating coil designed and developed specifically for this application. Process A three turn helical coil is used to braze the carbide to the shaft. The steel shaft is fluxed and the braze shim placed on top. The carbide tip is fluxed and placed on top of the shim, lining up the countersunk hole in the carbide. The hole is not fluxed because the flux outgases and causes the carbide to build up pressure and attempt to repel from the shaft. Power is applied for 85 seconds for the braze shim to flow and make a good joint. DAWEI’s customer has a customer who is unhappy with the braze quality of their digger so our customer is looking for a better quality brazing process. DAWEI’s customer is very happy with the sample brazed diggers and the help he received from the Ameritherm lab in developing his brazing process. Results/Benefits Induction heating provides: • Rapid localized heating only where needed • Creates clean, controllable joints • Hands-free heating that involves no operator skill for manufacturing • Even distribution of heating brazing carbide to shaft             induction brazing carbide to shaft               brazing carbide to stainless steel shaft https://dw-inductionheater.com/induction-brazing-carbide-to-stainless-steel.html?feed_id=244304&_unique_id=6636501477c8b
