Adopting Mn-Ni-Mo-Ti-B as main alloy system, a kind of SAW welding wire was developed, which can be applied to X100 ultra high strength pipeline steel. This welding wire is compatible with the corresponding BG-SJ101H2 flux. According to the standard requirements of Low-alloy Steel Electrodes and Fluxed for Submerged Arc Welding GB/T 12470-2003, through test of deposited metal, the result showed that the yield strength is 685 MPa, the tensile strength is 780 MPa , and the impact energy value is more than 27 J under-40℃After X100 steel pipe SAW welding, all the weld appearance, processing performance and mechanical properties are good, the tensile strength is more than 780 MPa, and the impact toughness is 100 J at-10℃. It realized good matching with high strength and high toughness, and can meet the requirements of X100 SAW pipe performance.
