Stage: PROBLEM TO BE SOLVED: To provide a technique for suppressing generation of cracks in a lap fillet-welded joint.SOLUTION: A method for welding a lap fillet-welded joint comprises a welding step of lap-welding the edge of a first steel material and the surface of a second steel material so as to form a welded part along the edge of the first steel material. In the welding step, the first steel material and the second welding material are welded so as to satisfy (W1>=6.0+2s-(t-T)) in a section orthogonal to a welding line of the welded part, in which W1 denotes the lap width (mm) of the first and second steel materials, T denotes the thickness of the first steel material, t denotes the thickness (mm) of the second steel material, and s denotes a gap (mm) between the first and second steel materials.SELECTED DRAWING: Figure 2 (Grant)
