Abstract
A butt-welded joint includes a pair of steel plates, a first weld metal that is formed at a butting portion of the pair of steel plates from a side of a first surface of the butt-welded joint to a side of a second surface opposite the first surface by irradiation of a first high-energy density beam from the side of the first surface, and a second weld metal that is formed by irradiation of a second high-energy density beam to cover an end surface of the first weld metal at the side of the first surface side of the first weld metal. A width Wof the first weld metal on the first surface and a width Wof the second weld metal on the first surface satisfy an equation 1.2≦W/W≦3.5, and a depth of the second weld metal from the first surface is 2.0 mm to 10.0 mm.
