Analysis of the advantages and disadvantages of brazing

 1. The brazing heating temperature is low, which has little effect on the structure and performance of the base material; 2. The brazing joint is flat and smooth, and the appearance is beautiful; 3. The deformation of the weldment is small, especially when uniform heating is used (such as brazing in a furnace). ) Brazing method, the deformation of the weldment can be reduced to a minimum, and it is easy to ensure the dimensional accuracy of the weldment; 4. Some brazing methods can weld dozens or hundreds of brazing seams at a time, with high productivity; 5 .Can realize the connection of dissimilar metals or alloys, metals and non-metals. However, brazing also has its own shortcomings: the strength of the needle welded joint is relatively low, and the heat resistance is relatively poor. The electrochemical corrosion caused by the large difference between the base material and the solder composition results in poor corrosion resistance and relatively high assembly requirements.
