浅谈焊缝超次返修对压力容器的影响

Discussion on the Influence of Over-repair of Weld on Pressure Vessel

公司在大型容器竖炉反应器制造过程中,出现焊缝同一部位超次返修的现象。本文主要从安全技术规范、标准要求,焊接、无损检测、理化检验方法等方面阐释了焊缝同一部位返修相应控制措施以及超次返修对压力容器焊缝质量产生的影响,对焊缝同一部位超次返修有一定的借鉴意义。

In the manufacturing process of large container shaft furnace reactor,the phenomenon of overrepair occurred in the same part of weld.This paper mainly explains the corresponding control measures for the repair of the same part of the weld and the influence of the over-repair on the quality of the pressure vessel weld from the aspects of safety technical specifications,standard requirements,welding,non-destructive testing,physical and chemical inspection methods,etc.It has certain reference significance for the over-repair of the same part of the weld.
