Abstract
A flux-cored wire for gas-shielded arc welding has a steel outer sheath filled with a flux. The flux-cored wire includes specific amounts, relative to a total mass of the wire, of TiO, at least one of Si, an Si oxide and an Si compound, C, Mn, Mo, Ni, at least one of metal Mg and an Mg alloy, an F compound, a K compound, an Na compound, B and a B compound, and Fe, respectively. A total content of each of Ti and a Ti alloy, metal Al and an Al alloy, and V is restricted to the specific range, respectively. A content of Ti is also restricted to the specific range relative to the total mass of the steel outer sheath.
