| Abstract: | The flaws of low-alloy high-strength steel pressure vessel were introduced, which frequently occur in the course of welding and after the welding has been finished. And the main factors that causing defects were analyzed. The quality of the welding joint was controlled through three aspects: making preparation prior to welding, the process of welding and postweld test. |
