Hydrogen Atmosphere Brazing Tube To Copper With Induction

Hydrogen Atmosphere Brazing Tube To Copper with induction Objective: Braze a NI-SPAN-C alloy tube to a steel cap in a hydrogen atmosphere Material NI-SPAN-C alloy tube (5mm) dia, steel cap (7mm) dia, (7mm) long, nickel braze, quartz tube and hydrogen Temperature: 1875 ºF (1024 ºC) Frequency: 350 kHz Equipment •DW-UHF-20kW induction heating system, equipped with a remote workhead containing two 1.5μF capacitors for a total of 0.75μF • An induction heating coil designed and developed specifically for this application. Process A single turn helical coil is used to heat the tube assembly directly. The tube assembly is held in place inside the quartz tube by a copper fixture and hydrogen is fed into the quartz tube. Braze preforms are placed at the braze area and heat is applied for 60 seconds to flow the braze. Results/Benefits Induction heating provides: • Rapid localized heat to joint area only • Minimized oxidation reduces cleaning time • Improved part quality • Hands-free heating that involves no operator skill for manufacturing https://dw-inductionheater.com/hydrogen-atmosphere-brazing-copper.html?feed_id=229506&_unique_id=6536a9069c51f
