Abstract

In this paper, a method of predicting welding residual stress in a T-joint using inherent strain (the source of residual stress) is verified by experiments. The measured inherent strains are compared with the results of thermal elastoplastic analysis and the simplified formulae proposed by some of the authers. Released strains along the welding direction of T-joints were measured by strain gages, and inherent strains were calculated from the released strains. The stress equilibrium across the cutting plane during releasing strains is necessary for determining the inherent strains accurately. Measured inherent strains in T-joints agree well with the results of thermal elastoplastic analysis and also with the simplified formulae which are presented within the scatter of the inherent strain distribution. The proposed method of predicting welding residual stresses using the inherent strains is experimentaly validated.
