Abstract: The present invention discloses a flux cored wire for arc welding of austenitic stainless steel which can restrain bending and high temperature cracking, and prevent a bead from being drooped. A flux filled in a sheath consisting of 18-8 stainless steel(C≦0.03 wt %, N≦0.02 wt %) comprises an alkali metal compound in an oxide converted amount of 0.05 to 1.0 wt % by weight of the welding wire, a metal fluoride in a fluorine converted amount below 0.08 wt %, Bi oxide in an amount below 0.1 wt %, Mn in an amount of 0.1 to 1.8 wt %, Cr in an amount of 2.0 to 4.0 wt %, SiO2 in an amount of 0.5 to 3.0 wt %, Al2O3 in an amount of 0.1 to 2.0 wt %, and TiO2 and ZrO2 wherein a ratio of (TiO2+ZrO2)/SiO2 is 0.8 to 1.6. Here, an amount of the flux filled in the sheath ranges from 15 to 35 wt % by weight of the welding wire.

Abstract: A flux cored wire for gas-shielded arc welding is disclosed. The flux cored wire is excellent in a zinc resistant primer performance and a low temperature impact toughness and comprises a flux filled in a mild steel sheath. The flux comprises: an oxide of TiO2+SiO2+Al2O3 in an amount of 2% to 10% by weight of the wire; at least one component in an amount of 0.1% to 1.0% by weight of the wire, the one component being selected from a metal fluoride group consisting of CaF2, NaF, K2SiF6, Na2SiF6 and KF, a metal titanium in an amount of 0.1% to 0.25 t % by weight of the wire; a metal boron in an amount of 0.002% to 0.008% by weight of the wire; and a subsidiary component in an amount of 5% to 20% by weight of the wire, the subsidiary component consisting of an iron component, a deoxidizer and an arc stabilizer.
