摘要： PROBLEM TO BE SOLVED: To provide a fatigue strength improving method for improving fatigue strength of a weld zone in a steel structure such as a steel bridge by introducing compressive residual stress, without imparting deformation causing a new stress concentration part to the weld zone, the method being suitably used for hammer peening.SOLUTION: A part of a base material surface separated from a weld toe part is plastically deformed by vertically striking to the base material surface, desirably, by striking so that a part of a plastic deformation area by striking, gradually superpose and moves to the outside from the toe part vicinal side by a chipper of a flat shape with a chamfered striking surface, and the compressive residual stress is introduced into the weld toe part. When forming a belt-like plastic deformation area on which a recess characteristic value (the product of the maximum depth and a width)(mm) has a predetermined value by contacting with the weld toe part, the weld toe part is stricken by a chamfered part of the flat part periphery of the striking surface of the chipper, and the base material is stricken by the flat part. When assuming that a width of the striking surface of the chipper used for striking as B, a part within B/4 from the toe part of the base material surface is plastically deformed by striking.

摘要： PROBLEM TO BE SOLVED: To provide a fatigue strength improving method for improving fatigue strength of a weld part of a steel structure like a steel bridge suitable for hammer peening by introducing a compressive residual stress without imparting any deformation forming a new stress concentration part in the weld part.SOLUTION: A part of the surface of a base material, which is apart from a weld toe, is struck perpendicularly to the surface of the base material with a flat chipper whose striking face is chamfered. Preferably, striking is moved gradually from the vicinity of the weld toe to the outside so that part of a plastic deformation area caused by striking is overlapped, and the compressive residual stress is introduced into the weld toe. When forming a belt-like plastic deformation area having a described value of a recess characteristics (the product of the maximum depth and width)(mm) while bringing it into contact with the weld toe, the weld toe is struck with the chamfered part of the periphery of the flat part of the chipper striking face, and the base material is struck by the flat part. When the width of the striking face of the chipper used for striking is made B, plastic deformation is performed by striking the portion within B/4 from the weld toe of the surface of the base material.
