On three models made from Trolon the edge stresses are determined by means of the photoelastic method for simplified conditions of resistance-welded joints of overlapped sheet metals of equal thickness. The stress maxima have been found at the edge of the seam they are 5.43 times the mean stress in the metal for the single singleshear joint and 1.75 times for the single double-shear joint and 4.3 times for the single-shear double joint. Fatigue ruptures of spot-welded joints start from positions where according to stress measurements the greatest pulling stresses occur. Author
