摘要： PROBLEM TO BE SOLVED: To control the low cycle fatigue to be caused by the differential strength between the weld metal in the fillet welding and the base metal. SOLUTION: After a groove 3 whose depth becomes smaller as a first member 1 is separated farther from an abutting part abutted on and formed in a surface of a second member 2 is formed in a surface of the second member 2, the fillet welding 4 is executed so that the thickness of the weld metal 5 is gradually reduced farther from the abutting part. Because the strength of the member is gradually reduced, the stress concentration caused by the differential strength between the weld metal 5 and the base metal which is experienced with the conventional method can be reduced, and the low cycle fatigue strength can be improved.
