摘　　要：乏燃料贮存格架安装于核电厂燃料厂房乏燃料贮存水池内,用于贮存达到规定限值的乏燃料组件。硼铝乏燃料贮存格架为核电站新型的贮存格架,每台贮存格架由一定栅距排列的垂直方形贮存小室构成,其中贮存套管之间为薄板奥氏体不锈钢连接焊缝。文章对激光焊焊接技术焊接贮存套管之间薄板奥氏体不锈钢T型接头的连接焊缝进行研究。采用激光焊设备验收试验基础上优化后的焊接工艺参数分别进行对接试件、模拟试件的焊接,焊后制备力学性能、化学成分分析、宏观、微观金相试样,结果证明可获得满足要求的相应质量准则的焊缝,同时验证了激光焊接头及配套设备与产品结构的适应性,尤其是与产品结构相同的模拟试件的焊缝成形、位置可影响焊接稳定性。The spent fuel storage grid is installed in the spent fuel storage pool of the nuclear power plant fuel plant,which is used to store the spent fuel assemblies that reach the specified limit.boron and aluminum spent fuel storage racks are new storage rack in nuclear power plant.each rack is composed of vertical square storage cells arranged in a certain spacing.the storage sleeves are connected by thin Austenitic stainless steel welding seams.in this paper,laser bean welding technique is used to weld the T-joints of thin plates between storage casings.the laser beam welding process parameters optimized on the basis of acceptance test of laser beam welding equipment were used to weld the jointed specimen and the simulated specimen.at the same time,the adaptability of the laser beam welding head and the matching equipment to the product structure is verified,especially the weld formation,position and welding stability of the simulative specimen which has the same product structure.
