Vacuum brazing technology advantage is introduced

Vacuum brazing technology since 40 s, has become a very promising welding technology. First appeared in the electronics industry in the brazing of copper and stainless steel parts, and then applied to the aviation industry, nuclear industry, started in 1959 is applied to the manufacture of stainless steel plate-fin heat exchanger. Now, they are widely used in air separation equipment, petrochemical equipment, engineering machinery, cars, boats and home appliance industries of plate-fin heat exchanger and cooler.
Because the vacuum brazing technology has incomparable advantages, so in the developed countries in the world get rapid development and wide application. Its advantages are as follows:
1. Vacuum brazing, because no soldering flux, significantly improve the corrosion resistance of the product, from all kinds of pollution, pollution-free processing equipment, has a good safety conditions;
2. The vacuum brazing not only save a lot of expensive metal soldering flux, and without complex flux of the cleaning process, reducing the production cost;
3. The wettability of vacuum brazing filler metals and liquidity is good, can weld more complex and narrow channel device, vacuum brazing improve the yield of the product, get strong clean face;
4. Compared with other methods, the internal structure of the furnace and fixtures such as long life, can reduce the maintenance cost of the furnace.
5. A lot of material is suitable for vacuum brazing, such as: aluminum, aluminum alloy, copper, copper alloy, stainless steel, alloy steel, mild steel, titanium, nickel, nickel by kang (Inconei) can travel through a vacuum brazing furnace, the designer according to soldering device USES to determine the required materials, including aluminum and aluminum alloy applied most widely.
