Zusammenfassung:	The self-protecting welding wire with flux core for pipeline steel has welding wire comprising BaF2, SrF2 and/or CaF2 7-12 wt%, LiF 0.8-3.0 wt%, CaO 0.2-0.8 wt%, SiO2 0.1-0.4 wt%, Al 1.2-2.0 wt%, Mg 1.2-2.0 wt%, Mn 0.6-1.2 wt%, Ni 0.6-1.2 wt%, C 0.05- 0.10 wt%, Zr 0.05-0.3 wt%, B 0.002-0.012 wt%, and Fe for the rest; and flux core accounting for 18-25 wt%. It contains water in 0.010-0.120 wt%, and has reduced current fluctuation and raised welding performance.
