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 Copper Assemblies With Induction

Brazing Copper Assemblies With Induction Objective:To heat copper ‘T’ assemblies to 1400(760) ºF(ºC) for brazing Material: Copper ‘T’ assemblies,Silver-copper eutectic braze,White flux Temperature: 1400(760) ºF(ºC) Frequency: 250 kHz Equipment: DW-UHF-20KW, 450 kHz solid state induction power supply with a remote heat station containing two 1.32 mF capacitors (total capacitance 0.66 mF). A custom-designed induction heating coil. Process A custom double-wound pancake-helical coil combination is used to efficiently transfer RF Induction Heating power. Tests were conducted using temperature indicating paint to establish heating profiles and time-to-temperature. After the optimum time-totemperature of 3-5 minutes is established, a braze ring is placed at the joint and white flux applied to the joint area. The first joint on each piece takes 5 minutes with subsequent joints on the same copper piece taking much less time (~3 minutes). Results/Benefits · Semi-automatic process reduces amount of operator laborinvolved· Easy and effective completion of braze joints https://dw-inductionheater.com/brazing-copper-assemblies-with-induction.html?feed_id=252562&_unique_id=66864b35df3a6
