  • SEAMLESS FLUX-CORED WELDING WIRE
    Publication number: 20190299340
    Abstract: This seamless wire containing welding flux is formed by filling a steel sheath with flux, the amount of Fe in the flux per total mass of the wire being 2-15 mass %, and the flux filling ratio being 10-30 mass %. When the amount (mass %) of Fe in the flux per total mass of the wire is X and the flux filling ratio (mass %) is Y, expression (1) is satisfied. By means of this seamless wire containing welding flux, variation in the flux cross-sectional area relative to the wire cross-sectional area, which is caused by a reverse airflow generated during a diameter reduction step, is reduced, and wire breakage during the diameter reduction step is prevented.
