北京航空工艺研究所同兄弟厂合作,运用该所专利技术“薄壁构件低应力无变形焊接法”,经过五年时间的艰苦努力,圆满完成攻关项目某型号铝合金贮箱筒段纵缝焊接变形控制研究。在京通过技术鉴定时,专家们认为,该成果已在某型号的焊接生产中得到成功应用,解决了铝合金贮箱筒段网格结构焊缝翘曲变形这一长期存在的技术难题,焊接变形控制达到了设计要求,接头力学性能和焊缝内部质量得到了进一步改善,结构可靠性和整体质量也得以提高,专家们还认为,这项成果是在专利技术指导下的具体应用和发展,在国内外属工程应用之首例,居于国际同类技术的先进水平;该成果对解决其他型号同类结构的焊接变形问题和提高产品质量,同样 Beijing Institute of Aeronautics and Astronautics cooperated with his brother factory to apply the patented technology “low-stress non-deforming welding of thin-walled components”, after five years of hard work, successfully completed the longitudinal seam welding of a certain aluminum alloy tank segment of the research project Deformation Control Research. When passing the technical appraisal in Beijing, the experts think that the achievement has been successfully applied in a certain type of welding production, which has solved the long-standing technical problem of the warp and deformation of the welded structure in the aluminum alloy cylinder section of the barrel. The welding deformation The control meets the design requirements, the mechanical properties of the joint and the internal quality of the weld have been further improved, the structural reliability and overall quality have also been improved, and experts also believe that the result is the specific application and development under the guidance of patented technology. The first case of domestic and foreign engineering applications, living in the international advanced level of similar technologies; the results of other types of similar structures to solve the problem of welding deformation and improve product quality, the same
