摘　　要：秦山核电厂二期扩建工程反应堆堆内构件3#吊篮筒体在制造过程中出现严重焊接变形,导致功能丧失。对造成这一不符合项的原因进行了分析。对4#吊篮筒体的焊接采取了包括修改焊接工装、修改焊接工艺与参数、施加反变形等措施,以尽可能地减小焊接变形。结果表明,4#吊篮筒体焊接结果满足设计要求。The paper analyzes the severe deformation in the welding of core barrel in Qinshan Nuclear Power Phase II Extension Project Reactor 3# unit,which nearly induces the loss of the function of the core barrel.Measures such as improving the welding fixture,process and parameter,and loading the counterweight is taken for the 4# unit to minimize the deformation,and the result shows that the weld of the 4# core barrel satisfies the design requirements.
