Induction Brazing Steel To Carbide Plate
Objective Brazing a steel piston valve assembly
Material Steel piston valve 4.5โ dia (11.43cm), tungsten carbide plateย and braze
Temperature 1350 ยบF
Frequency 100ย kHz
Equipment โขDW-UHF-40kW induction heating system, equipped with aย remote workhead containing six 1.0ฮผF capacitors for a totalย of 1.5ฮผF
โข An induction heating coil designed and developedย specifically for this application.
Process A five turn pancake coil is used to braze the piston valve andย tungsten carbide plate. The assembly was heated for 10ย minutes to flow the braze and join the two pieces.
Results/Benefits Induction heating provides:
โข Rapid localized heat, which can minimize oxidation andย reduce cleaning after joining
โข Hands-free heating that involves no operator skill forย manufacturing
โข Clean and controllable joints
โข Produces high quality repeatable parts
