PROBLEM TO BE SOLVED: To provide a flux-cored wire improved in corrosion resistance (intergranular corrosion resistance and high temperature oxidation resistance) and excelling in burn-through resistance and welding workability, and a gas-shielded arc welding method using the flux-cored wire.SOLUTION: A flux-cored wire for stainless steel welding with flux filled within a stainless steel or mild steel outer skin as well as for gas-shielded arc welding using a shielding gas contains the predetermined amount of C, Si, Mn, P, S, Cr, Ti, O to the total mass of the flux-cored wire with a remaining portion consisting of Fe and inevitable impurities. The shielding gas is pure Ar gas. |
