PURPOSE: A metallic flux-cored wire for a gas-shielded arc welding is provided to control the generation of spatter and to prevent the decrease of arc stability by controlling the content of carbon. CONSTITUTION: A metallic flux-cored wire for a gas-shielded arc welding comprises C 0.2~ 0.4 weight%, Si 3.0~5.5 weight%, Mn 8.0~11.0 weight%, Ni 8.0~12.0 weight%, Mg 1.5~2.5 weight%, Al2O3+ SiO2: 3.5~6.5 weight%, tiO2 15.0~20.0 weight%, the rest comprises iron and inevitable impurities. The metallic flux-cored wire for the gas-shielded arc welding comprises the first or the second kinds of Na and K with 1.0~5.0 weight%.
