Abstract

A flux-cored wire for arc welding of a duplex stainless steel includes a stainless-steel sheath filled with a flux and contains, with respect to the total mass of the wire, predetermined amounts of Cr, Ni, Mo, N, Mn, and Si, in which letting a Ti alloy content in terms of Ti be [Ti] and letting an Al alloy content in terms of Al be [Al], [Ti] and [Al] are predetermined values, and in which parameter A expressed as A=[Ti]+2×[Al] satisfies a predetermined value, and the balance is composed of Fe, a slag-forming component, and incidental impurities.
