【摘要】：通过介绍焊接工艺在商用航空发动机中的应用,分析了焊接工艺选用时的原则,即材料的焊接性、焊接接头的性能要求、焊接变形、焊接工艺和焊后检验的可达性4个原则,最后结合国内现状提出了国内研制商用航空发动机项目中对先进焊接技术的研究与应用、焊接性能数据的完善、焊接结构完整性评估方法的建立等方面的迫切需求,以推进国内加快焊接技术的研究,尽快建立完整的商用航空发动机焊接工艺体系,提升国内商用航空发动机的研制水平。
[Abstract]:By introducing the application of welding technology in commercial aero-engine, this paper analyzes the principles of welding process selection, that is, the weldability of materials, the performance requirements of welded joints, welding deformation, welding process and accessibility of post-weld inspection. Finally, according to the present situation in China, the research and application of advanced welding technology and the perfection of welding performance data in the domestic commercial aero-engine project are put forward. There is an urgent need for the establishment of welding structure integrity assessment method in order to speed up the research of welding technology in China, establish a complete welding process system of commercial aero-engine as soon as possible, and improve the development level of domestic commercial aero-engine.
