[Problem] To prevent decreases in fatigue strength of a base material by relieving the residual stress of a weld. [Solution Means] A method for welding a deposit metal to a base material wit h reduced residual stress, comprising a step of welding a deposit metal to a base material; and a step of plastically deforming, into a recess, an area on the surface of the base material around a peripheral portion of the deposit metal. The invention is also directed to a welded block joint between a wire and a base material, characterized by comprising a deposit metal receiving an end portion of the wire and welded to the base material, wherein an area whi ch is plastically deformed into a recess is formed on the base material surface at a periphera l portion of the deposit metal. |
