摘要

环焊缝的强度匹配形式和耐腐蚀性对管道可靠运行至关重要。文中分别采用低强匹配、等强匹配和高强匹配三种匹配形式对D1219×18.4 mm X80螺旋焊管进行焊条电弧焊，对焊接接头进行抗氢致开裂（HIC）试验，并综合包括化学成分、微观组织、接头强度和韧性等各种因素分析，研究不同强度匹配形式对X80管线钢环焊缝抗氢致裂纹性能的影响。结果表明，三种匹配方式下的X80管线钢焊接接头的抗HIC性能均能满足相关要求，且采用三种强度匹配焊条焊接接头的裂纹长度敏感率（CLR）、裂纹厚度敏感率（CTR）以及裂纹敏感率（CSR）随着匹配强度的升高而升高；焊缝金属的C、P、S含量对HIC敏感性有显著影响，降低这些元素的含量有助于提高焊缝的抗HIC性能；微观组织观察表明，焊缝金属的组织类型和形态对HIC敏感性也有重要影响，热力学平衡且稳定的细小组织是抗HIC的理想组织。

Abstract

The strength matching form and corrosion resistance of girth welds are crucial for the reliable operation of pipelines. In this paper

shielded metal arc welding was used on D1219×18.4 mm X80 spiral welded pipes with low strength matching

equal strength matching

and high strength matching. The weld joints were subjected to hydrogen-induced cracking (HIC) tests

and the effects of different strength matching on the HIC resistance of X80 pipeline steel girth welds were analyzed comprehensively

including chemical composition

microstructure

joint strength

and toughness. The results show that the HIC resistance of the X80 pipeline steel weld joints under the three matching forms can meet the relevant requirements. Moreover

the crack length sensitivity ratio (CLR)

crack thickness sensitivity ratio (CTR)

and crack sensitivity ratio (CSR) of the weld joints increase with the increase of matching strength. The content of C

and S in the weld metal has a significant impact on HIC sensitivity

and reducing the content of these elements helps to improve the HIC resistance of the weld. Microstructure observation indicates that the type and morphology of the weld metal also have an important influence on HIC sensitivity. A thermodynamically balanced and stable small tissue is an ideal tissue for HIC resistance.
