摘要
CPR1000核电项目常规岛蒸汽及高压给水联箱均采用WB36CN1钢。对于WB36CN1联箱,特别是当角焊缝施焊部件(筒身与接管)尺寸较大时,角焊缝焊接质量不高一直困扰着制造厂家。针对某核电项目常规岛主蒸汽联箱角焊缝返修的情况,分析其原因并指出焊接及返修的注意事项,对其它WB36CN1钢的焊接及焊缝返修具有一定的借鉴意义。
All the steam and high press feeding water header are made of WB36CN1 steel in the CPRIOOO nuclear power plant.For the header made of WB36CN1 steel,especially when the size of fillet weld is large,there are always some weld defects.The reasons of weld defect were analyzed,and some key points of repairing were proposed,which can provide some references for the other weld and repairing of WB36CN1 steel weld.
