Main application of vacuum diffusion welding

Diffusion welding is mainly used for welding small, precise and complex weldments that are difficult to meet quality requirements by welding and brazing. In recent years, diffusion welding has solved the welding problems of various special materials in the technical fields such as atomic energy and aerospace missiles. For example, the connection of important components such as wings, doors, fuselage frames, engine rotor blades, guide blades, turbine disks, nozzle fairings, fan blades, etc. of advanced aircraft; thrust chambers and tail nozzles of rocket engines; aerospace Key components such as aircraft laminate injectors and honeycomb panels of aerospace aircraft. Diffusion welding is also widely used in the machinery manufacturing industry, such as inserting cemented carbide (or carbide) blades into heavy tools.

Main applications of vacuum brazing

Since the beginning of the 1940s, vacuum brazing technology has become a very promising welding technology. At present, the vacuum brazing process has been promoted and popularized in the fields of aviation, aerospace, atomic energy, electrical instruments, petrochemicals, automobiles, and tools. In terms of aero engine applications, Pratt & Whitney’s JT9D engine honeycomb sealing ring is made of vacuum brazing rings and honeycomb sandwich cores; the engine fuel manifold and stainless steel heat exchanger are composed of vacuum brazing; JTBD engine 12 , 13-stage compressor stator ring is made by vacuum brazing of inner and outer rings and dozens of blades. The engine casing of GE in the United States is also made by three-step vacuum brazing of more than 240 0.25-0.7~ thick Inconel alloy parts. Domestically, Shenyang Liming Engine Company and Chengdu Engine Company have vacuum brazed and some parts are applied to aero engines. In recent years, with the development of science and technology, especially the high-speed development of the home appliance industry (especially the refrigeration industry, including refrigeration equipment such as refrigerators, air conditioners and their three-way and four-way valves), the automobile industry, and the electronics industry, The application of brazing technology is becoming more and more extensive.

Main application of vacuum crushing

Mainly used for tools, molds, cutting tools and mechanical parts with relatively high technical requirements and complex shapes. The processed materials include W18Cr4V, W6Mo5Cr4VZ, Cr12, Cr12MOV, gCrsi, CrWMn, 3CrZWS, GCr15, 40Cr, 9Cr13, 3Cr13, 50CrV, 60512, 17-4PH, 15-7MOPH, ICr13NigTs, QBeZ and other materials. At the same time, machining or welding aluminum alloys and titanium alloys with complex shapes and high dimensional accuracy requirements also has the advantage of maintaining dimensional stability that other heat treatments cannot match.
