摘要:
A flux-cored wire for gas shielded welding use which can reduce the oxygen of weld metal to obtain a weld joint which is excellent in toughness and which enables all-position welding by direct current reverse polarity, wherein the wire contains, by mass % with respect to the wire total mass, CaO: 0.2 to 7.0%, one or more of MgF2, CaF2, SrF2, and BaF2 in a total of 1.0% or more (total of fluorides and CaO being 3.0 to 12.0%), one or more of Si, Al (less than 0.3%), Ti, Mg, Zr, Ca, Ce, and La in a total of 0.2 to 2.0%, and one or more oxides of Si, Mn, Al, Ti, B, and Zr in a total of 0.2 to 3.0%, α=C+Si/30+Mn/20+Cu/20+Ni/60+Cr/20+Mo/15+V/10+Nb/10+5B is 0.15 to 0.40%, P and S in a total of 0.040% or less, a balance of Fe, an arc stabilizer, unavoidable impurities, and a content of iron powder in the flux of 5.0% or less.
