The Hot-Ductility Results of Selected Alloys. circular weld beads was 6 in. (see Fig. 18.8). The welds were made with stationary inert-gas tungsten arc torches while the disk rotated around its center in a vertical plane. This technique was selected in order to minimize the bending effect associated with the transverse shrinkage. For the radius and thickness ratio of our specimen, it is correct to assume that the stress distribution associated with the weld shrinkage is planar. The perpendicular shrinkage is negligible; that is, there are no stresses perpendicular to the plane of the disk. With these assumptions, the stress distribution may be determined by measuring only the tangential strain on the rim of the disk while machining a series of concentric sections beginning at the disk center. We followed essentially the “boring Sachs” nrethod which was set up for pipes. Since plane ,
