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

Induction Brazing Steel Pipe

Induction Brazing Steel Pipe

Objective: To heat a stainless steel pipe, ferrule and elbow assembly to 1400°F (760°C) within 20 seconds for brazing.

Material 6″(152.4mm)long x 0.5″(12.7mm) diameter stainless steel conduit, 0.5″(12.7mm) long x 0.5″(12.7mm) diameter ferrule, 2″(50.8mm) elbow with 0.5″ (12.7mm) diameter

Temperature 1400°F (760°C)

Frequency 400 kHz

Equipment • DW-UHF-6KW-I induction heating system equipped with a remote workhead • An induction heating coil designed and developed specifically for this application.

Process: A specially designed, three-turn helical coil is used to provide heat to the assembly at the braze joint area. Two small silver solder braze rings are placed at each joint; the joints are coated with black flux to insure that the braze material flows cleanly. The assembly is placed inside the coil and power is applied for 15 seconds to cause the braze to flow.

Results/Benefits: Induction heating provides: • Consistent and repeatable results • No flame process • Faster process time
