摘　　要：介绍了 SJ10 1— G烧结焊剂的化学成分和研制过程 ,通过对 SJ10 1— G烧结焊剂配合H0 8C焊丝焊接 X70管线钢的焊缝力学性能的解剖分析 ,指出采用传统的熔炼焊剂、SJ10 1等烧结焊剂其焊缝不能满足标准关于韧性的要求。并通过大量的 X65、X70级管线钢的生产试验 ,指出SJ10 1— G烧结焊剂配合 H0 8C焊丝焊接 X65、X70级管线钢管焊缝 X射线探伤可达到 级标准要求 。The article introduces the chemical composition research and development of the SJ101-Gsinter weld flux. Through analysis of weld seam mechanical properties of X70 pipeline steel welded with SJ101-G sinter weld flux and H08C welding wire, it points out that the conventional melting flux , SJ101 sinter weld flux can not meet the weld seam toughness requirement of the specification . through the large quantity X65 and X70 grade pipeline steel production test, it points out that the SJ101-G sinter weld flux and the H08C weld wire can weld X65 and X70 grade linepipe, and the X-ray detection of weld seam can meet the 1 level requirement, the toughness also meet the requirement of the specification.
