摘要
介绍了反应堆压力容器下底圆中子测量管的焊接工艺。基于某制造厂发生的该焊缝相关的下底圆J型坡口隔离层堆焊预热质量问题,分析了预热、层间温度等焊缝质量影响要素及该质量问题的处理方案,为今后类似问题的处理和提高J型坡口隔离层的堆焊质量提供参考。
The welding procedure of instruction tube on lower dome of reactor pressure vessel was briefly introduced. The affecting factors for quality of welding joint such as preheating and interpass temperature were analyzed based on a preheating quality problem of J type groove buttering happened on a certain manufacturer. Additionally, the related disposition measures were summarized. The analysis can provide the reference for the treatment of similar problem and help improve the welding quality of J type groove buttering layer.
