Vacuum brazing is carried out in the absence of air, using a specialized furnace, and delivers significant advantages: extremely clean, flux-free braze joints of high integrity and superior strength. Improved temperature uniformity when heating in a vacuum, and lower residual stresses due to slow heating and cooling cycle, results in significantly improved thermal and mechanical properties of the material.
Vacuum high temperature brazing furnace It is mainly used for vacuum brazing of stainless steel, titanium alloy, hard alloy, non-ferrous metal, etc. It is also suitable for heat treatment and vacuum sintering of metal materials such as gas quenching and annealing of alloy steel such as tool steel and die steel.
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.

One of the most common forms of high temperature brazing is accomplished in a vacuum furnace and referred to as vacuum brazing. Parts to be joined are cleaned, paste brazing filler metal is applied to the surfaces to be joined, then placed into the furnace. The entire assembly is brought to brazing temperature, after the furnace has been evacuated of air, to eliminate any oxidation or contamination occurring as the braze filler metal melts and flows into the joints.
Wall Colmonoy is the pioneer in furnace brazing of high-temperature base metals using nickel-based filler metals. Aerobraze Engineered Technologies, a division of Wall Colmonoy, has eight brazing/heat treating furnaces at their Cincinnati facility, including the world's largest top-loading vacuum furnace at 120" dia. X 180" high.
High Temperature Brazing uses vacuum or protective atmosphere furnaces to join complex assemblies made in stainless steels or other high alloy base materials. The technology is used for the manufacture of heat exchangers used in diverse applications, in the manufacture of gas turbines and in the automotive sector for the manufacture of catalytic converters and exhaust gas recyclers.
These aerospace-type vacuum furnaces can typically operate as high as about 2400°F (1300°C), and temperature uniformity in the chamber can be controlled by varying the amount of power sent to each of those heating elements. In such a case, each heating element might then be called a separate heating "zone."
Apr 14, 2017 · Vacuum brazing furnace: the key features The vacuum furnace, given its high uniformity within the hot zone of the entire temperature curve, is the ideal system to carry out an identical heating cycle on a high number of loads as well as continuous brazing on larger pieces. It is furthermore capable of repeating the same cycle accurately.
Heat Sources for Brazing Vacuum furnace A furnace with electrically heated elements that surround the workload and heat the brazing filler metal to the liquidus state so flow and capillary attraction are achieved. To permit brazing of alloys that are sensitive to oxidation at high temperatures, a pumping system is employed that removes oxygen.
High temperature brazing in single chamber vacuum furnaces by Björn Eric Zieger Compared to conventional soldering techniques the batch type vacuum brazing has established for various products. Also for the large-scale production of copper brazed plate heat exchangers the vacuum process is used. The compacted
High vacuum, high temperature brazing furnace The successful outcome of any brazing operation is that the mating surfaces of the joint are substantially free from oxide films when brazing alloy melts and flows.
The vacuum high temperature brazing furnace is mainly used for brazing brazing and brazing copper brazing. It is also used in sintering of powder materials. According to the brazing process of special materials, the design of vacuum unit and temperature control of hot zone are optimized.
