摘要
The present invention relates to the fatigue strength of an overlap welded joint (10), wherein an overlap portion (12a) of a first steel member (12) and an overlap portion (14a) of a second steel member (10). 14) overlap, and the edge portion of the first steel member (12) is welded to the surface (14b) of the second steel member (14) by means of a welded portion (16) extending along the portion of border, which is enhanced by the following method. first, when the direction perpendicular to the extension direction of the welded part (16) and parallel to the surface (14b) of the second steel element (14) as the reference direction (y), the movement of the overlapped welded joint (10) in the reference direction (y) is prevented, and movement of the first steel element (12) and second steel element (14) in the plate thickness direction is prevented. in that state, a portion (14a) of the second steel element (14) is heated to form a molten part (18) in the portion (14a) of the second steel element (14).
