PROBLEM TO BE SOLVED: To provide a wire for gas-shielded arc welding which is suitable for the welding of high Ni based highly weather resistant steel, enables satisfactory welding operability, particularly satisfactory slag peeling properties and imparts corrosion resistance to sea salt to a weld metal without deteriorating the corrosion resistance of a base metal. SOLUTION: The solid wire for gas-shielded arc welding of high Ni based weather resistant steel has a composition containing, by mass to the total mass of the wire, 0.03 to 0.15% C, 0.2 to 1.2% Si, 0.8 to 2.0% Mn, 1.0 to 5.5% Ni, 0.1 to 1.0% Cu, 0.01 to 0.1% Ti, 0.02 to 0.1% S, 0.0002 to 0.01% B,≤0.025% P and≤0.10% Cr, and preferably containing 0.01 to 0.3% Bi as well, and in which the content of S+Bi is 0.03 to 0.2%, and the balance Fe with inevitable impurities.
