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 on the basis of the development of metallurgy and chemical technology, the brazing technology developed rapidly 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. For example, 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 with different materials and different structures for various purposes, Brazing technology is widely used in the manufacture of motor parts and components such as blades and ties of steam turbines. In the production of light industry, brazing technology is widely used in medical equipment, metal implants, musical instruments, household appliances, cooking utensils, and bicycles.
For the electronics industry and instrument manufacturing industry, brazing is the only feasible connection method in a wide range. For example, in the production of components, a large number of metal and ceramic, glass and other non-metal connections are involved, and heating must be prevented in wiring connections. The damage to the components depends on the brazing technology. In nuclear power plants and marine nuclear power plants, important components such as fuel element positioning frames, heat exchangers, and neutron detectors are often brazed.
