Research on Charpy Impact Energy of LSAW Pipe

  • 摘要: 随着控轧控冷技术的发展,钢厂出于成本考虑,在钢板中添加的合金元素含量逐渐减少,导致制管后的管线用钢管焊缝的夏比冲击功下降。为了提高直缝埋弧焊管焊缝的夏比冲击性能,选择了2 种焊丝、5 种焊剂,进行了X65 钢级直缝埋弧焊管焊材的交叉匹配试验;分析了不同焊材匹配方案下焊缝的冲击性能、化学成分及组织,并确定出最优方案。试验结果可为后续类似钢级的微量合金管线钢的焊接提供参考。
    Abstract: Along with the development of the TMCP technology,in order to control the cost by the steel works,the contents of alloy elements as added in the pipeline steel plate is getting less and less,which directly leads to the decrease of Charpy impact energy of the weld seam of the finished linepipe.To enhance the Charpy impact energy of the said linepipe,two types of welding wires,and five welding agents are selected to conduct the cross-matching test to the welding materials of the X65 LSAW pipe;and analyses are made for the impact energy,the chemical composition and the microstructure of the weld subjected to different welding material matching solutions so as to determine the best solution.The test result is worth using as the reference for welding of the micro-alloyed linepipe steel in similar steel grade in the future.
