SEAMLESS WIRE CONTAINING WELDING FLUX

Title:

SEAMLESS WIRE CONTAINING WELDING FLUX

Document Type and Number:

WIPO Patent Application WO/2018/043268

Kind Code:

A1

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. Y > −2X + 19 (1)
