Abstract
A welded joint of steel plates having a plate thickness of 50 mm or more and a method for manufacturing the welded joint are disclosed. In the welded joint of the steel plates having a plate thickness T of 50 mm or more, the weld metal includes single-pass-per-layer multiple layers, the first ratio [A/p] of the sectional area A of the weld metal in a direction perpendicular to a weld line to the number of weld layers p is 120.0 mm2/layer or less, and the second ratio [H/W] of the height H to the width of each of the layers of the weld metal is 1.00 or less.

A welded joint of steel plates having a plate thickness T (mm) of 50 mm or more, comprising:
- a weld metal including single-pass-per-layer multiple layers,
- wherein a first ratio [A/p] of a sectional area A (mm2) of the weld metal in a direction perpendicular to a weld line to the number of weld layers p (layers) is 120.0 mm2/layer or less, and
- a second ratio [H/W] of a height H (mm) to a width W (mm) of each of the layers of the weld metal is 1.00 or less.
