Rotary vane vacuum pump in vacuum welding application characteristics:
1. Vacuum brazing
, because there is no brazing agent, has significantly improved the corrosion resistance of the product, exempted from all kinds of pollution, pollution-free disposal equipment costs, has good safe consumption conditions;
2. Vacuum brazing not only saves a lot of expensive metal brazing agent, but also does not require complex solder cleaning process, reducing the cost of consumption;
3. Vacuum brazing filler metal has good wetness and activity, and can weld devices with more complex and narrow channels.
4. Compared with other methods, the internal structure of the furnace and fixtures and other long life, 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 and so on can be brazing in vacuum furnace, the designer according to the use of brazing device is sure to need the data, aluminum and aluminum alloy is the most common application.
