| description | PROBLEM TO BE SOLVED: To provide a new improvement method of fatigue strength applicable even to a narrow part covered with another member.SOLUTION: An improvement method of fatigue strength of the present invention generates a spark between a first splice plate 2A, a second splice plate 2B and a fastener 3, by arranging the fastener 3 that is an auxiliary tool for assisting improvement processing, by opposing to the first splice plate 2A and the second splice plate 2B that are a processing object for attaining the improvement processing of the fatigue strength. In the improvement method of the fatigue strength of the present invention, a fine crack C generated on a peripheral edge surface 7 can be repaired by causing welding by the occurrence of the spark on the peripheral edge surface 7 of a fastening hole 5 of the first splice plate 2A and the second splice plate 2B.SELECTED DRAWING: Figure 1
【課題】狭隘でかつ他の部材によって覆われている部分にでも適用できる、新規な疲労強度の向上方法を提供する。【解決手段】本発明の疲労強度の向上方法は、疲労強度の向上処理が図られる処理対象物である第一スプライスプレート２Ａ，第二スプライスプレート２Ｂと対向して、向上処理を補助する補助具であるファスナ３を配置し、第一スプライスプレート２Ａ，第二スプライスプレート２Ｂとファスナ３の間にスパークを発生させることを特徴とする。本発明の疲労強度の向上方法において、第一スプライスプレート２Ａ，第二スプライスプレート２Ｂの締結孔５の周縁面７にスパークの発生による溶着を生じさせることにより、周縁面７に生じている微小亀裂Ｃを修復することができる。【選択図】図１ |
