PROBLEM TO BE SOLVED: To provide a flux cored wire for welding stainless steel which wire has excellent corrosion resistance, very little generation of blowholes and pits, and superior weldability, and also to provide a welding method of a galvanized steel sheet and a stainless steel sheet. SOLUTION: The flux cored wire for gas-shielded arc welding, in which flux is filled in a metallic jacket, is characterized in that it contains in the metallic jacket and the flux, by mass to the total mass of the wire: 0.01-0.05% C, 0.10-0.45% Si, 0.2-1.0% Mn, 13-20% Cr, 0.5-1.0% Nb, 0.01-0.3% Cu, 0.2-0.8% Al, 0.1-0.8% Ti, and the balance Fe and inevitable impurities. The flux cored wire for gas-shielded arc welding is also characterized in that it is used in performing welding for lap joint, Tee joint or flare joint between a galvanized steel sheet or a galvanized steel bar and a stainless steel sheet.
