Abstract
A gas shielded arc-welding flux cored wire having a steel-made sheath filled with flux. The flux cored wire containing, by weight % based on the total weight of the wire, 1.0% or more Si--Mn ferroalloy powder having a grain size of 212 .mu.m or less; 2.0 to 7.0% TiO.sub.2 ; 0.2 to 1.5% SiO.sub.2 ; 0.1 to 1.2% ZrO.sub.2 ; and 0.01 to 0.3% fluoride (F-converted value). The powder comprises, by weight %, 0.40 to 1.20% C, 5 to 12% Si, 19 to 42% Mn, and the balance of Fe, with Si 2.gtoreq.11.89-2.92 C-0.077 Mn (Equation (1)) satisfied.
