Study was undertaken in an attempt to measure the residual stresses in weld, where the effects of rolling residual stress in specimen, rate of cooling and rigidity of clamping were investigated. Two types of stress were measured ; i) the macroscopic residual stress indicated by shift of diffraction peak and ii) the microscopic residual stress indicated by broadening of diffraction profile. In welded specimens of as-rolled mild steel macroscopic residual stress was higher by the level of the macroscopic rolling residual stress than in welded specimens of annealed plate ; if specimens were cooled in water immediately after welding, the maocrscopic residual stress was increased by thermal stress of cooling ; and if specimens clamped in welding, the macroscopic residual stress in bead was higher than in specimens not clamped. Meanwhile, the microscopic residual stress value was monotonically decreased in welded specimens of annealed plate, as the point of measurement get farther from the bead ; however, in specimens of as-rolled plate, microscopic residual stress value, observed once to decrease from its maximum value at the center of the bead in the heat affected zone about the bead locally, was observed to increase somehow again thereafter until the value of the microscopic rolling residual stress level is attained in the farther part of specimen.
