Advanced solder the technology makes medium application in aviation

It is OK that Han receives a technology to have reduce structural weight apparently, reduce production cost, raise the characteristic such as structural function, technical oneself solders to also innovate ceaselessly inside the category of technical domain in the meantime with development, the new-style engineering technology that development gives is designed for advanced aviation structure and make offerred a technology to prop up. Change to pledging gently as aviation weaponry and its power plant, the demand that creates macrobian life, low cost, high reliably, advanced solder the technology will have mainer and mainer effect. Rise ceaselessly as what aviation weaponry function asks, used new material, new structure increasingly. The occurrence of these new material and new structure promoted the property of the product, but solder to including at the same time technology inside aviation production technology raised taller requirement. In recent years, active welding flux solders technology of technology of solder of new-style drill rod and technology, diffusion welding technology, agitate friction welding, linear friction welding, high-energy bundle stream solder technology and welding stress are out of shape control technology solder advancedly the technology made a domain obtain in aviation a series of development and application, beijing aviation production project studies the research respect that is in these technologies began fruitful work. Active welding flux solders technical active welding flux solders the technology is a domestic and international research is more in recent years kind of new technology, this technology basically applies at TIG to solder at present process, namely A-TIG solder. A-TIG solders the most apparent characteristic in the process is electric arc contractive, frit is deep increase. Compare with photograph of groovy TIG solder, the craft advantage with A-TIG main solder still includes: Reduce solder hot input quantity, improve result of welding line figuration, rise solder efficiency. In recent years, the scientific research orgnaization such as institute of Beijing aviation production project, Harbin Institute of Technology and university of Gansu Province industry and school are in the development of recipe of active welding flux of the material such as alloy of mild steel, stainless steel, titanium, aluminium alloy and magnesium alloy, solder mechanism and project change application to consider to waited for a respect to begin fruitful work. Mild steel and product of welding flux of stainless steel active had been on the product such as pipeline of high-pressured boiler pipeline, oil win application. Welding flux already was in the stainless steel active that by Beijing aviation production project institute develops orbit of high speed train solders on realize large quantities of quantity application, and the set of welding flux of titanium alloy active that develops development by its is mature the product is OK one-time solder the titanium alloy plank that the biggest ply amounts to 6mm, replaceable convention drives the technology of groove multi-pass welding in TIG solder, make work efficiency rises greatly. Use this series welding flux to solder when the titanium alloy of identical norms is laminose, solder hot input quantity can reduce 60% above, and occurence rate of solder coherent aperture is reduced significantly, this to improving quality of titanium alloy welding line, reduce welding stress and be out of shape have positive result. At present this series product has been used in development of complex aviation structural member and production, wait like moire bridge, ventral, this is explicit spaceflight store application also was won in the titanium alloy product such as ball of titanium of box, high pressure, in popularizing application to solder to the product is developed and be produced at other titanium alloy at present. Because active welding flux solders,the technology has the advantage that improves result of welding line figuration, domestic and international Scientists and Technologists is trying to use this technology at plasma solder, laser beam welding and electron beam to solder in craft, the issue that with solving these soldering figuration of methodological welding line needs, obtained certain result [1-5] . Development of welding wire of core of medicine of the development of recipe of active welding flux that waits for new material in alloy of heat-resisting high temperature, aluminium alloy and magnesium alloy, active welding flux and solder the research respect of mechanism scored abecedarian gain [6-10] , but should realize project application to still need to begin more thorough research work.
