摘要： A flux-cored wire for gas shielded arc welding according to the present invention is formed by filling a steel casing with flux, wherein: the flux contains, by mass percentage to the total mass of the wire, titanium dioxide: 4.0 to 8.0%, alkali metal fluoride (fluorine equivalence): 0.02 to 0.40%, and PTFE (fluorine equivalence): 0.02 to 0.40%; the fluorine equivalence of alkali-earth metal fluoride is regulated to 0.01% or less by mass; and the fluorine equivalence of alkali metal fluoride and the fluorine equivalence of PTFE satisfy the following expressions; (fluorine equivalence of alkali metal fluoride)/( fluorine equivalence of polytetrafluoroethylene) : = 1, and (fluorine equivalence of alkali metal fluoride + 0.35)/( fluorine equivalence of polytetrafluoroethylene) = 1.By the configuration, diffusible hydrogen is prevented from intruding into a weld during arc welding and the wire is excellent in resistance to hygroscopicity and further shows good welding operability.

摘要： Provided is a welding metal in which the chemical component composition thereof is appropriately controlled; an A value that is specified by a predetermined relational expression satisfies the requirement of being 3.8% to 9.0%; an X value that is specified by a predetermined relational expression satisfies the requirement of being 0.5% or greater; the area percentage of carbide particles having a circle-equivalent diameter of 0.20 µm or greater in the welding metal is 4.0% or less; and the number of carbide particles having a circle-equivalent diameter of 1.0 µm or greater is 1000 particles/mm 2 or less. This welding metal, which can exhibit not only high strength but also good low-temperature toughness and good drop-weight characteristics, is useful as a material for a pressure vessel in a nuclear power plant.
