Explains the three choices for a brazing atmosphere. A controlled atmosphere can be produced in a vacuum furnace, a sealed “glove box” or with an atmospheric bell jar. With a bell jar Inert atmospheres of nitrogen, argon, hydrogen and dissociated ammonia are common choices for controlled atmosphere brazing.
Working zone of 1200 x 1200 x 1200; Maximum operating temperature of 1400ºC; Maximum gross load of 1500kg; Can operate with a partial pressure of Nitrogen, Argon or Hydrogen; Gas quench option; Meets the requirements of AMS-2750 Version E. Vacuum Brazing is commonly used by the following market sectors:.
The ability of hydrogen to reduce the metal oxides on the surface is determined by temperature, hydrogen gas purity and pressure. Hydrogen furnace brazing is done in a pure dry hydrogen gas atmosphere at a slightly positive pressure in a vacuum furnace. The brazing temperature is dependent on the base metal being
Vacuum furnace brazing is a metal joining process that takes place in a chamber known as a vacuum furnace at well below atmospheric pressure. When compared with other processes, this joining technique offers significant advantages: durable, flux-free braze joints of high structural integrity. Rigorous temperature

Vacuum furnaces and humpback furnaces have been the traditional systems used to braze stainless steel because of their ability to ensure a very low oxygen to be reduced at 1900°F. In a humpback furnace and a straight through brazing furnace, the reduction is typically achieved through a reaction of hydrogen with the
the vacuum furnace with an equivalent dew point of -90°C(-130°F) even if. 10- 4 torr is for water vapor. Therefore, the cleanliness of a vacuum atmosphere is expected to be better compared to that of a hydrogen atmosphere. However, brazing in vacuum has an inherent disadvantage with respect to high vapor pressure
