摘要
针对CPR1000核电站核岛主管道用厚壁不锈钢核岛主管道预制焊接中的焊接变形问题,采用理论分析与模拟试验相结合的研究方法,系统地研究了核电站核岛主管道预制焊接不同装配结构的焊接变形特点,确立了主管道预制焊接的反变形措施,保证了主管道预制焊接质量。
The article focused on the welding deforming issues of thick-walled stainless steel for reactor coolant piping(RCP) during the prefabrication,which be used in CPR1000 Project.By theoretical analysis combining with simulative test,the dynamic welding deforming characteristics of all kinds of welds in thick-walled stainless steel RCP prefabrication was studied systemically.An anti-deforming method for RCP prefabricating welding had been obtained,which ensured the welding quality of RCP successfully.
