| Abstract: | The crack is often formed at the termination of longitudinal seam while the 16MnR steel pressure vessel's body is welded by auto-submerged arc welding(SAW). This article analyses the causes of the crack and provides the preventive measures such as improving arc blow-out plate. The welding trial results show that the preventive measures of crack are satisfactory. |
