摘要
通过焊缝抗裂性试验及焊接接头机械性能试验，对用于ＳＰＶ３５５ＮＳＲ钢制球罐的焊接工艺进行了系统的评价．同时还对ＳＰＶ３５５ＮＳＲ钢材在焊接过程中成分及组织的变化进行了一些研究．
By means of cracking resistance tests and mechanical properties tests, a welding technology used for the globular pressure vessel made of SPV355 NSR steel was evaluated in detail, and the composition and microstructure changes of the steel during the welding was investigated too. 〖KH*2D]
