Induction Brazing Carbide to Steel

Induction Brazing Carbide to Steel  Objective: Braze a carbide sleeve to a steel 'T' shank Material :2.0" (51mm) OD carbide sleeve, 1.0" (25.5mm) high braze joint, 1.5 " (38 mm) steel 'T' , 50% silver braze ring Temperature: 1292 ºF (700 ºC) Frequency: 257 kHz Equipment • DW-UHF-6KW-I induction heating system, equipped with a remote workhead containing two 0.66μF capacitors for a total of 1.32 μF. • An induction heating coil designed and developed specifically for this application. Process A pancake/helical combination coil is used to heat the assembly. The coil design allows easy loading and unloading of the parts without having to rotate them. A few minutes after the start of the heat cycle the heat pattern normalizes and becomes very uniform. For better joint quality a chamfered groove is machined in the steel shank to locate and seat the braze ring. The braze alloy flows into the joint creating a strong, aesthetic bond. The amount of braze alloy heated each cycle is controlled well by the braze ring. Results/Benefits Induction heating provides: • Hands-free brazing which requires no special operator skills for manufacturing • Precise, even heat is applied and is divided equally between the shank and the carbide. This provides an even flow of the braze alloy as the parts reach brazing temperatures. https://dw-inductionheater.com/induction-brazing-carbide-to-steel.html?feed_id=250944&_unique_id=66774c491cb52

Induction Brazing Steel To Carbide Plate

Induction Brazing Steel To Carbide Plate Objective Brazing a steel piston valve assembly Material Steel piston valve 4.5” dia (11.43cm), tungsten carbide plate and braze Temperature 1350 ºF Frequency 100 kHz Equipment •DW-UHF-40kW induction heating system, equipped with a remote workhead containing six 1.0μF capacitors for a total of 1.5μF • An induction heating coil designed and developed specifically for this application. Process A five turn pancake coil is used to braze the piston valve and tungsten carbide plate. The assembly was heated for 10 minutes to flow the braze and join the two pieces. Results/Benefits Induction heating provides: • Rapid localized heat, which can minimize oxidation and reduce cleaning after joining • Hands-free heating that involves no operator skill for manufacturing • Clean and controllable joints • Produces high quality repeatable parts https://dw-inductionheater.com/induction-brazing-steel-to-carbide.html?feed_id=249813&_unique_id=666bdf20c06c2
