Weld material, gas metal arc welding method, and welded structure

摘要

An object of the present invention is to provide a weld material which contains 8 to 13 % Cr, and can be used with the GMA welding method, a GMA welding method which has superior arc stability and can provide a welded material having superior properties, and a welded structure; in order to attain this object, a weld material is provided, which contains in weight, 0.01 to 0.15 % C, 0.1 to 0.6 % Si, 0.1 to 2.0 % Mn, 8 to 13 % Cr, 0.1 to 1.5 % Ni, 0.3 to 2.0 % Mo, 0.05 to 0.5 % V, 0.08 to 0.5 % W, 0.5 to 5.0 % Co, 0.1 to 0.5 % Ta, ≤ 0.08 N, 0.01 to 0.1 % REMs, and consisting of the balance Fe with inevitable impurities.
