【Summary Description】 Diffusion technology also has a long history. In more than 3000 BC, the Egyptians joined two pieces of hot metal together by hammering, which may be the oldest form of solid-phase diffusion welding. In the Bronze Age of 700 BC, the British hammered gold into boxes at room temperature, which should be regarded as the earliest cold welding. Next, diffusion welding technology has experienced a long development process. However, it was not until World War II that diffusion welding technology developed rapidly. This is because the two sides of the war in order to pursue higher aircraft flight performance, the need to achieve a reliable connection of high-strength aluminum alloy components. The rapid development of vacuum technology also promotes the progress of diffusion welding technology. In addition, the development and requirements of the aviation industry have also promoted various forms of diffusion welding. For example, in the 1970 s, TLP diffusion welding techniques were developed primarily for joining high strength cast superalloys. At present, the technology is also used to connect new structural materials such as titanium alloys, ceramics, and intermetallic compounds. Another example is the titanium alloy LID welding process developed in the early 1970 s, which can obtain titanium alloy joints with uniform microstructure and composition. At present, solid-phase diffusion welding is mainly used to manufacture parts of different materials or porous materials, such as streamline analysis elements, porous filter elements, electromagnetic coil skeletons and some bimetal parts. TLP diffusion welding and cap welding are used for high-strength joining of high-temperature alloy and titanium alloy components in the aerospace industry.
