Abstract

Base materials of a butt welded joint with a welded portion have a carbon concentration of 0.1 mass % or greater and 0.35 mass % of less. The welded portion is formed by heating by keyhole welding and then reheating by heat conduction welding, and the welded portion has a melted and solidified portion by the keyhole welding, a reheated solidified portion by the heat conduction welding, and a remelted and solidified portion. A width W0 and a depth d0 of the melted and solidified portion and a width W1 and a depth d1 of the remelted and solidified portion have the following relationships: 0.46W0≤W1; and 0.14d0≤d1≤0.73d0.
