What are the advantages of vacuum brazing furnace?

Vacuum brazing furnace has a series of significant advantages, which make it widely used in the field of metal brazing. The following are the main advantages of vacuum brazing furnaces, presented in a point wise and inductive manner:

High welding quality:
Due to welding in a vacuum environment, the influence of impurities such as oxygen on the welding process is effectively avoided, resulting in no oxidation or sticking of the welded joint, uniform welding seam, and high strength.
The vacuum environment is conducive to removing grease and oxide film on the surface of the workpiece, and improving the brightness of the part surface.

Fast welding speed:
The vacuum brazing furnace can activate higher heating power during welding, improving welding speed and reducing production cycle.

Can weld multiple metals:
Vacuum brazing furnace is suitable for welding various metal materials, such as aluminum, aluminum alloy, copper, copper alloy, stainless steel, alloy steel, low-carbon steel, titanium, nickel, etc., meeting the needs of different industries for metal connections.

Environmentally friendly and pollution-free:
During vacuum brazing, there is no need to use brazing flux, which significantly improves the corrosion resistance of the product, eliminates various pollutants, and is beneficial for environmental protection and safe production.

Cost savings:
Vacuum brazing not only saves a large amount of expensive metal brazing flux, but also does not require complex flux cleaning processes, reducing production costs.

Good welding effect:
The wettability and flowability of vacuum brazing filler metal are good, which can weld more complex and narrow channel devices, improve product yield, and obtain a sturdy and clean working surface.

Long equipment lifespan:
Compared with other methods, the internal structure and fixtures of vacuum brazing furnaces have a longer lifespan, which reduces the maintenance cost of the furnace.

Low heating temperature:
The lower heating temperature during vacuum brazing has a smaller impact on the physical and chemical properties of the base metal, which is beneficial for maintaining the material’s properties.

Small deformation of parts:
During vacuum brazing, the deformation of the parts is small, making it easy to ensure the dimensional accuracy of the assembled parts.

Widely applicable:
Vacuum brazing furnace can be used for vacuum aluminum brazing of aluminum plate fin heat exchangers, air conditioning evaporators, automotive heat exchangers, radar grid antennas, waveguide tubes and other products. It can also be used for high-temperature brazing of materials such as stainless steel, titanium alloy, hard alloy, high-temperature alloy, etc., to meet the needs of different industries.

In summary, vacuum brazing furnaces have shown excellent performance and broad application prospects in the field of metal brazing due to their high welding quality, fast welding speed, ability to weld multiple metals, environmental protection and pollution-free, cost saving, good welding effect, long equipment life, low heating temperature, small part deformation, and wide application.
