Abstract

The present invention relates to a welded joint of a floating offshore wind-power-generation equipment including a tower member, a float member, and a bracket. The present invention provides a welded joint exhibiting increased fatigue strength at a weld with weld beads extended onto the float member, and a method of manufacturing the same. A welded joint according to the present invention includes a first weld bead, a second weld bead, and a third weld bead. The first weld bead extends along one of short edges of a rectangular contact surface at which a bracket is in contact with a float member. The second weld bead and the third weld bead extend along two respective long edges of the rectangular contact surface and are each extended over a corresponding one of a starting end and a terminal end of the first weld bead onto the float member. Furthermore, it is preferable that a ratio M/N of an interval M between a distal end part of the second weld bead and a distal end part of the third weld bead and a length N of an extended portion of the second weld bead or the third weld bead be 2.0 or smaller.
