In order to consider the mechanism of welding cracks and the relation between the types of welding cracks and the residual stresses, the stresses induced by welding on the surfaces of rectangular and groove-slit type specimens of mild steel as shown in Fig. 1 and Fig. 2 were determined by the X-ray diffraction method. Stresses were calculated from the shift of the cobalt K α_1 ring diffracted by the surface of the specimen. The measurements were carried out at twelve points on the rectangular specimen and at seven points on the groove-slit type specimen. Silver powder was adopted as the standardizing medium. The result values are shown in Table 6 for the former and in Table 7 for the latter. The distributions of stresses are to be easily seen in Fig. 6 and in Fig. 7. The author considered the relation between these observations and the results of his previous research on welding cracks.
