Vacuum Brazing Furnace Introduction
Vacuum brazing refers to the heating of work piece in a vacuum chamber. It is mainly used for welding products with high quality and easily oxidized materials. The vacuum brazing furnace includes a pressure vessel having a cylindrical side wall and a door, the door being sized and positioned to close one end of the cylindrical side wall. The work piece handling system is mounted on the pressure vessel door to support the heat treatment or brazing of the metal work piece. The work piece processing system includes means for rotating the work piece during processing. The vacuum system can be connected to the work piece so that the pressure inside the work piece is below atmospheric pressure during brazing.
advantages of vacuum brazing
1. Vacuum brazing, due to the absence of flux, significantly improves the corrosion resistance of the product, eliminates all kinds of pollution, pollution-free processing equipment, and has good conditions for safe production;
2. Vacuum brazing not only saves a lot of expensive metal flux, but also does not require complex flux cleaning process, reducing production costs;
3. Vacuum brazing solder has good wettability and fluidity, can weld more complex and narrow channel devices, vacuum brazing improves product yield, and obtains a strong and clean working surface;
4. Compared with other methods, the internal structure of the furnace and fixtures have a long life, which can reduce the maintenance cost of the furnace;
5. There are many materials suitable for vacuum brazing, such as: aluminum, aluminum alloy, copper, copper alloy, stainless steel, alloy steel, low carbon steel, titanium, nickel, Inconei, etc. can be brazed in a vacuum furnace. The designer determines the required materials based on the use of the brazing device, of which aluminum and aluminum alloys are most widely used.
Vacuum brazing application
Stainless steel heat exchanger, plate-fin oil cooler, cooler made of silver-free copper vacuum brazing process, aluminum radiator brazing, vacuum brazing impeller,vacuum flask brazing furnace etc.
