【Summary Description】 A generation of materials, a generation of manufacturing, a generation of equipment. As one of the important methods of material connection, brazing (including diffusion welding) is recognized as the key connection technology of advanced aircraft and engines together with electron beam welding, laser welding and friction welding. Various titanium alloy and stainless steel pipes on the aircraft body are connected by high-frequency induction brazing during the assembly process to achieve the purpose of weight reduction. A large number of wires and instruments on the onboard equipment are also connected by soldering. For aircraft with a flight Mach number greater than 2.5, brazing or cap welding is increasingly used for honeycomb panels of stainless steel, titanium alloys or high-temperature alloys due to the high temperature of the skin due to friction with the air. The manufacture of a large number of important parts of aero-engines, such as turbine blades, compressor blades, combustion chamber parts, honeycomb sealing structures, blade ring structures, stainless steel heat exchangers, aluminum alloy chassis, fuel manifolds and other pipelines., Without brazing or TLP diffusion welding technology. The engine rectifier, guide vane and casing are connected by brazing, which not only meets the design requirements, but also achieves the effect of weight reduction. According to statistics, an aero-engine core machine brazing area of more than 14000 cm2. It can be said that without advanced brazing and special joining technology, it is impossible to manufacture many important high-temperature structural parts of high-performance aeroengines. With the development of aviation technology, more and more new materials, new structures and new manufacturing technologies will be used in future aviation equipment. Brazing and its derived joining technologies, such as TLP diffusion welding and cap welding, have unique advantages and flexibility in joining new materials and manufacturing complex fine structures. Even for some new materials and complex components, brazing is the only feasible connection technology, which is increasingly used in important load-bearing components. There is no doubt that brazing technology plays an important role in the aviation industry.
