Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a weld metal of corrosion resistant steel and a solid wire for submerge arc welding of corrosion resistant steel suitable to weld corrosion resistant steel excellent in weather resistance and coating resistant peelability even under an environment with a large amount of flying salt content such as a seashore region.MEANS: A weld metal with corrosion resistant steels welded with each other contains, by mass% with respect to a total mass of weld metal, C:0.03-0.15%, Mn:1.2-2.0%, Cu:0.02-0.35%, Sn:0.05-0.40%, Si:0.15-0.80% with Al:0.05% or less, P:0.025% or less, S:0.020% or less, and the remainder consists of Fe and impurities. A solid wire for submerge welding to form the weld metal contains C:0.02-0.15%, Si:0.005-0.05%, Mn:1.5-3.5%, Cu:0.01-0.35%, Sn:0.05-0.40%, with Al:0.05% or less, P:0.025% or less, S:0.020% or less, and the remainder consists of Fe and impurities.SELECTED DRAWING: None
