In this study, basic experiments were carried out by two dimensional photoelasticity and photoelastic coating in order to find the reasons for the difference of fatigue failure locations in fillet welds of cover plate type joint and tee type joint as shown in Table 1. From the results, it is summarized as follows. (1) The stress concentration factor at root is larger than that at toe in fillet weld for small values of 2W/M, where W=weld leg length and M=main plate thickness, while for large values the former is less than the latter. (2) The fatigue failure locations in fillet weld shown in Table 1 are dependent upon the relative amounts of stress concentration at root and toe. (3) The stress concentration factors given by photoelastic coating are less than those by two dimensional photoelasticity.
