This paper deals with a non-destructive detection method of fatigue crack in spot-welded joints under tensile-shear repeated load.We developed the non-destructive method, according to which the generation time, the crack length and the propagation speed of fatigue crack can be quantitatively estimated by utilizing information obtained from strain gages bonded on the electrode indentations of spot welds. Specimens used in this experiment are made of various kinds of thin steel sheets.
