摘　　要：研究了具有不同合金元素钒和铬的两种石油用钢管 ,在对其经过不同热处理后进行环缝焊接。对其焊接接头进行性能测试和金相组织分析 ,表明通过合理选择焊接工艺 。In this paper, the girth welding was carried out after two kinds of oil pipeline steel with different content of V and Cr were heat treated by the different specification. The properties and microstructure of welded joints were analyzed. The experiments showed that the welded joint of oil pipeline could be satisfied with the requirements by optimizing the welding procedure.$$$$
