Although brazing technology appeared earlier, it has not been greatly developed for a long time. After entering the 20th century, its development lags far behind fusion welding technology. It was not until the 1930s that brazing technology developed rapidly on the basis of the development of metallurgy and chemical technology, and gradually became an independent industrial production technology. Especially after the Second World War, due to the development of new technologies such as aviation, aerospace, nuclear energy, and electronics, the adoption of new materials and new structural forms put forward higher requirements on connection technology, and brazing technology has therefore received greater attention. Attention, rapid development, there have been many new brazing methods, and their applications are becoming more and more extensive.

Manufacturing various tools for machining, especially cemented carbide tools, drilling tools for drilling and mining, various pipes and containers, water tanks for automobiles and tractors, heat exchangers of different materials and different structures for various purposes, motor parts As well as the manufacture of steam turbine blades and ties, brazing technology is widely used. In the production of light industry, brazing technology is widely used in medical equipment, metal implants, musical instruments, household appliances, cooking utensils, and bicycles.
