In Part I of this report the investigations on radial contraction and reaction stress occured in the central region due to circular patch-welds were stated. This second part concerns with the studies on residual stress occured in these specimens. Distribution of measured strain and residual stress are shown in Fig. 2 and 3, respectively. In the region of patch welded plate, the signs of radial stress σγ and circumferential stress σθ are both tensile, on the other hand, σγ is positive and σθ, negative in the outer ring. However, the distribution of residual stress does not constitute a fair curve, but a much complicated one along the welding bead. Therefore, it seems to be difficult to control the residual stress along the welding bead by the change of welding procedures. When the specimen is cut along the weld line, elastic dislocation is produced according to the stress reliese due to slitting. The value of dislocation is fairly smaller than that of radial contraction. Moreover, some investigations were made concerning with the radial contraction in block welding sequence. The effect of block length in block sequence and that of overlaying bead on radial contraction were studied.
