摘要
搅拌摩擦焊作为一种新兴的固相连接技术,其焊接接头质量高、焊接产品变形小,一经问世即受到各行各业特别是航天工业的青睐。美国、日本及欧洲各国均对搅拌摩擦焊技术进行了大量深入的研究,并广泛应用到运载火箭燃料贮箱的焊接生产中,实现了运载火箭贮箱全搅拌摩擦焊接的工程化应用。中国对搅拌摩擦焊技术的研究起步相对较晚但发展迅速,近几年里在工程化应用上取得了较大的成就,目前在中国运载火箭燃料贮箱焊接中已得到成功的应用。随着对搅拌摩擦焊技术机理及工程化研究的不断深入,搅拌摩擦焊技术正向着设备智能化、工艺集成化和生产高效化的方向发展。
As a new solid-phase joining technology,friction stir welding( FSW) has advantages such as high quality of welded joint and small deformation of welding products. Once it is available,it is favored by all walks of life,especially the aerospace industry. In the United States,Japan and European countries,a lot of in-depth research had been conducted on the friction stir welding technology,and it had been widely applied to the welding production of rocket fuel tanks,and the engineering application of the full friction stir welding to the rocket fuel tank had been realized. Research on friction stir welding technology developed late in China but progressing fast. In recent years,great achievements had been made in the application of engineering. At present,it has been successfully applied to the welding of fuel tanks for launch vehicles in China. With the research on the technical mechanism and engineering of friction stir welding being investigated further,friction stir welding technology is developing in the direction of intelligent equipment,process integration and high production efficiency.
