Induction Brazing Steel To Carbide Plate
Objective Brazing a steel piston valve assembly
Material Steel piston valve 4.5ā dia (11.43cm), tungsten carbide plateĀ and braze
Temperature 1350 ĀŗF
Frequency 100Ā kHz
Equipment ā¢DW-UHF-40kW induction heating system, equipped with aĀ remote workhead containing six 1.0Ī¼F capacitors for a totalĀ of 1.5Ī¼F
ā¢ An induction heating coil designed and developedĀ specifically for this application.
Process A five turn pancake coil is used to braze the piston valve andĀ tungsten carbide plate. The assembly was heated for 10Ā minutes to flow the braze and join the two pieces.
Results/Benefits Induction heating provides:
ā¢ Rapid localized heat, which can minimize oxidation andĀ reduce cleaning after joining
ā¢ Hands-free heating that involves no operator skill forĀ manufacturing
ā¢ Clean and controllable joints
ā¢ Produces high quality repeatable parts
