摘要

The fatigue strength of a lap-welded joint, wherein an overlapping portion of a first steel material and an overlapping portion of a second steel material overlap with each other, and an edge portion of the first steel material is welded to a front face of the second steel material with a weld zone extending along the edge portion, is improved. First, when a direction perpendicular to an extending direction X of the weld zone and parallel to a front face of the second steel material is defined as a reference direction Y, the lap-welded joint is restrained from moving in the reference direction Y, and the first steel material and the second steel material are restrained from moving in their sheet-thickness directions. In this state, a portion of the second steel material is heated such that a melted portion is formed in the portion of the second steel material.
