Abstract

Previous studies have suggested that the application of stress during weld cooling could change the microstructure and residual stress state of a weld. Flat bar specimens were welded in a prestressed condition of tensile or compressive stress. The longitudinal residual stresses were found to decrease with application of tensile pre-induced stresses and to increase with application of compressive pre-induced stresses. Away from the weld toe the transverse residual stresses were found to decrease and near the weld toe the residual stresses were found to increase with application of tensile pre-induced stresses. With application of compressive pre-induced stresses the transverse residual stresses were found to increase. The present study suggests that the prestressing method should not be used as a residual stress relieving mechanism.
