【摘要】 吊篮筒体是核反应堆堆内构件的重要组成部分,设计公差与间隙要求苛刻。本文首先分析了筒体类设备焊接变形产生的原因,并针对这些原因,提出了具体的控制措施。然后结合秦山核电二期扩建工程反应堆堆内构件3号堆吊篮筒体在制造过程中出现的严重焊接变形,把防变形控制策略用于改进4号堆吊篮筒体的焊接,焊接结果满足设计要求。更多还原

【Abstract】 Core barrel is an important part in React Vessel Internals(RVI) and the design of tolerance is quite strict.Firstly, the paper analyses the reasons of welding deformation in core barrel and with the reasons,the paper presents control measures to solve welding deformation.Then,combining the severe deformation in the welding of core barrel in Qinshan Nuclear Power PhaseⅡextension Project Reactor 3# unit,the paper supply control measures to the 4# unit and the result of weld satisfy the requirements and the result satisfy design requirement.更多还原
