Advantages of brazing

(1) The lower heating temperature of brazing has little influence on the microstructure and sexual excitation of the base material;

(2) The brazing joint is smooth and smooth with a beautiful appearance;

(3) Small deformation of welding parts, especially the brazing method using uniform heating (such as brazing in furnace), the deformation of welding parts can be reduced to the minimum degree, easy to ensure the dimensional accuracy of welding parts;

(4) Some brazing methods can be welded into dozens or hundreds of brazing joints at a time, with high productivity;

(5) It can realize the connection between heterogeneous metal or alloy, metal and non-metal.

Disadvantages of brazing

The needle welding joint has low strength, poor heat resistance, poor corrosion resistance and high assembly requirements due to the electrochemical corrosion caused by the large difference between the base metal and the solder.
