摘要

Abstract invention patent: "structure welded with at least three drops of laser weld arranged along a closed curve is virtual, and corresponding method of laser welding.The invention relates to a welded part (1) formed in a junction between a plurality of steel plates (10) which is formed of a plurality of drops (11) arranged along a curve FECHada virtual (12), and when the thickness of the thin steel plate (10) of steel plates (10) is noted by T, the diameter D of each of the droplets (11) is 3vt or less.And the distance P between adjacent drops is 2D or more but not more than 5D, and the number of drops is three or more.
