Abstract
A flux-cored wire for gas-shielded arc welding of heat-resisting steel in the form of a steel tube filled with a flux, which is characterized in that the content of slag-forming agent is 6.10-9.90 mass % (based on the total mass of the wire), said steel tube and said flux all together contain less than 0.20 mass % C., 0.06-1.40 mass % Si, 0.55-1.60 mass % Mn, 0.004-0.090 mass % Cu, 0.004-0.090 mass % Ni, less than 2.60 mass % Cr, and 0.3-1.20 mass % Mo (based on the total mass of the wire), and said flux contains 4.2-8.2 mass % TiO , 0.025-0.25 mass % of metal fluoride (in terms of fluorine), and 0.20-1.50 mass % Mg. The flux-cored wire has both good welding maneuverability and ability to give weld metal with good mechanical properties, such as strength and toughness.
