Title:

GAS-SHIELDED ARC WELDING WIRE AND GAS-SHIELDED ARC WELDING METHOD

Document Type and Number:

WIPO Patent Application WO/2019/116917

Kind Code:

A1

Abstract:

Provided are: a gas-shielded arc welding wire which enables automatization of welding (continuous automated welding) even with use of a high-Cr welding material by suppressing welding defects such as fusion failure and bead shape defect; and a gas-shielded arc welding method. A gas-shielded arc welding wire which is characterized by containing, in mass% relative to the total mass of the wire, 0.01-0.50% of C, 0.01-1.50% of Si, 0.10-2.50% of Mn, 5-15% of Cr, 0.05-1.50% of Ni, 0.1-2.0% of Mo, 0.1-1.0% of V, 0.01-0.20% of Nb, 0.001-0.050% of REM, 0.0010-0.0200% of S, and 0.025% or less of O (including 0%), and which is also characterized by satisfying formula (1). (1): 3.0 ≤ (Nb + 10 × REM)/(S + O) ≤ 200.0
