摘要支承柱组件位于压水堆上部堆内构件上支承组件与上堆芯板之间,为位于驱动线上的导向筒组件提供支撑与连接作用。支承柱组件的全焊接结构使其焊接精度要求很高。本课题以支承柱组件的筒体激光对接焊为研究对象,对激光焊热源、激光焊焊缝收缩量和激光焊焊接变形进行建模和分析,建立CAP1400支承柱组件激光焊变形模拟技术,为制造技术研究提供理论指导。具体研究内容包括:激光焊试验和温度、宏观焊缝成形、残余应力测试;热源模型建立及参数确定;激光焊焊缝收缩模型及焊接变形预测。

Abstract: The supporting column is between the upper part and the core board of the RVI in the PWR .it provides support and connection for the guide tube assembly on the drive line. It belongs to all-welded structure, therefore, it is very critical for the welding manufacturing precision. This subject mainly studies the tube laser butt joint of supporting column components. We mainly model and analyze on the laser welding heat source, laser weld contraction and laser deformation. It provides theoretical guidance for manufacturing technology. The details are as follows: laser wel-ding experiment and temperature, macro molding of welding, the residual stress test, the establishment of heat source model and determination of parameters, the laser welding contraction model and welding deformation prediction.

Key words: supporting column laser welding numerical simulation stainless steel
