摘　　要：X100管线钢屈服强度在690MPa以上,为了实现钢管埋弧焊缝的高强度高韧性匹配,研制了与X100管线钢相匹配的WS01焊丝,该焊丝匹配大西洋CHF105焊剂,焊接接头抗拉强度810MPa,-20℃冲击功,焊缝的弯曲、硬度实验结果均达到API5L钢管标准要求。This article introduces the welding test method and technology for the X100 pipeline steel. Since yield strength of X100 pipeline steel is above 690MPa, WS01 welding wire is invented in this study to realize high strength and malleability joint for submerged-arc welding of the steel with ATLANTIC CHF105 flux. The tensile strength of the welding joint is 810MPa. According to the results of impact test at -20℃, bending test and hardness measurement, the properties of the weld bead have proved to meet the request of API5L steel pipes.
