摘要
A solid wire for gas shielded arc welding comprising the following in terms of mass-% with respect to a total mass of the wire including plating: C: from 0.03 to 0.15%, Si: from 0.2 to 0.5%, Mn: from 0.3 to 0.8%, P: 0.02% or less, S: 0.02% or less, Al: from 0.1 to 0.3%, Ti: from 0.001 to 0.2%, Cu: from 0 to 0.5%, Cr: from 0 to 2.5%, Nb: from 0 to 1.0%, and V: from 0 to 1.0%, wherein the balance is Fe and impurities, and the following value of X is in a range of from 1.5 to 3.5 mass %. A welding metal, wherein the X value of the following formula is in a range of from 1.0 to 4.0%. Further, a welded joint, a weldment, and a welding method of the welded joint, utilizing the solid wire or the weld metal. X=2×[Si]+[Mn]+3×[Ti]+5×[Al]
