摘要:
介绍了螺旋埋弧焊管预精焊生产工艺,对预精焊工艺生产X70钢级?准 1 016 mm×17.5 mm螺旋埋弧焊管焊接接头拉伸试验、夏比冲击试验、维氏硬度试验等试验结果进行了统计分析,并与传统的一步法工艺进行了对比。结果表明,预精焊生产工艺焊接接头抗拉强度与一步法工艺基本相当,夏比冲击韧性、维氏硬度等性能略优于一步法工艺,综合力学性能良好,满足《西气东输二线管道工程用X70螺旋缝埋弧焊管技术条件》要求。
Abstract:
This article introduced production process of two-step welding, statistically analyzed test results of X70 ?准 1 016 mm×17.5 mm SAWH pipe welded joints, such as tensile test, Charpy impact test and Vickers hardness test, and compared two-step welding process with traditional one-step welding process. The results indicated that welded joint tensile strength of the two-step welding process is basic equivalent to that of traditional one-step welding process, the Charpy impact toughness and Vickers hardness are better than those of the one-step method weld joint. The comprehensive mechanical properties of welded joints are good, which can meet the requirements of the technical specification of X70 SAWH line pipe for the 2nd West-east Pipeline Project.
