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 https://dw-inductionheater.com/induction-brazing-steel-pipe.html?feed_id=253065&_unique_id=668a9431e0f3d

Brazing Steel To Steel Pipe With Induction

Brazing Steel To Steel Pipe With Induction  Objective: To braze O-ring Face (ORFS) sleeve or male connector to a steel tube. Material • Steel tube, 1 inch (2.54 cm) OD • O-ring Face Seal sleeve and a male connector fittings • Preform braze rings • White SureFlow flux • Steel support mandrel Temperature 1300 ºF (704 ºC) Frequency 200 kHz Equipment • DW-UHF-20KW induction heating system, equipped with a remote workhead containing two (2) 1.5 μF capacitors (for a total of 0.75 μF). • An induction heating coil designed and developed specifically for this application. Process A four-turn 2.75 inch (7.0 cm) ID helical coil is used for heating both the steel tube and the ORFS sleeve or the ORFS male connector. This coil is designed to braze either the sleeve or male connector to the tube. The parts to be brazed are assembled with flux and heated for 45 seconds. Pressure is applied to the tube to make sure it is inserted fully into the fittings as the braze ring flows. Results/Benefits Advantages : • Large Inner diameter of coil allows for easy loading and unloading of parts • With efficient energy coupling of the coil to the fittings overheating is avoided. https://dw-inductionheater.com/brazing-steel-to-steel-pipe-with-induction.html?feed_id=251012&_unique_id=667803160f4db

Brazing Golf Ball With Induction

Brazing Golf Ball With Induction Objective: Heating steel golf ball mold to brazing dimple insert Material: Golf ball mold 2” in diameter, braze flux paste, dimple insert Temperature: 1400 ºF (760 ºC) Frequency: 260 kHz Equipment • DW-UHF-10kW induction heating system, equipped with a remote workhead containing two 0.5μF capacitors for a total of 0.25 μF • An induction heating coil designed and developed specifically for this application. Process A four turn helical coil is used to heat the golf ball mold to 1400ºF (760 ºC) in 3 minutes and the dimple insert is brazed to the mold with braze flux paste. Results/Benefits Induction heating provides: • No flame process. • Reliable, repeatable, non contact and energy efficient heat in minimal time. • Even distribution of heating. https://dw-inductionheater.com/brazing-golf-ball-with-induction.html?feed_id=250439&_unique_id=66724c817804f

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

Induction Brazing Steel Tips

Induction Brazing Steel Tips with Hihg Frequency Heating System Objective To heat a steel tip and shank assembly to 1300°F (704°C) within 3 seconds for brazing with induction heating instead of torch brazing.
