深冷压力容器闭环缝内咬边缺陷的解决办法

The solution method of cryogenic pressure vessel closed-loop seam internal undercut defects

通过统计深冷压力容器闭环缝焊接的一次合格率,确定了深冷压力容器闭环缝内咬边缺陷产生的类别及频率,并针对缺陷的产生原因,提出了具体的防治措施,达到了改善焊接质量的目的。

Through the statistical a qualified rate of cryogenic pressure vessel closed-loop seam welding,this paper determined the type and frequency generated by cryogenic pressure vessel closed-loop seam internal undercut defects,and according to the reasons of defects,put forward specific control measures,to improve the quality of welding.
