Flux-cored wire and gas-shielded arc welding method using the same

摘要

There is provided a flux-cored wire containing flux within a stainless steel or mild steel outer cover for use in stainless steel welding and gas-shielded arc welding using a shielding gas. The flux-cored wire contains, based on the total mass of the flux-cored wire, predetermined amounts of C, Si, Mn, P, S, Cr, Ti, and O. The remainder are Fe and incidental impurities. The shielding gas is pure Ar gas.

主权项

1. A flux-cored wire, comprising:
based on a total mass of the flux-cored wire: C:0.10% by mass or less, Si: 1.50% by mass or less, Mn: 2.00% by mass or less, P: 0.050% by mass or less, S: 0.050% by mass or less, Cr: 15.0% to 25.0% by mass, Ti: 0.16% to 1.00% by mass, O: more than 0.04% by mass and less than or equal to 0.300% by mass, and Fe being the principal element, wherein the flux-cored wire is suitable for stainless steel welding and gas-shielded arc welding using pure Ar gas as a shielding gas.
