Abstract
An object of the present invention is to provide a flux-cored wire for gas shielded arc welding, which has merits of both solid wire and flux-cored wire, the merits being high depositing properties and a small amount of slag generated of solid wire and stable welding workability of flux-cored wire. A flux-cored wire for gas shielded arc welding, in which flux is filled in a steel sheath, containing 0.3 to 1.8% (total wire mass percentage, the same rule applies to the following) of Si, 0.8 to 4.0% of Mn, and 0.15 to 2.0% of a synthetic material containing Na2O and TiO2 or a synthetic material containing Na2O, SiO2 and TiO2 as an arc stabilizer, with a flux filling percentage of 3 to 10% by mass.
