This report describes the results of an investigation of the weld distortions produced in the welding of two simply supported plates. The analytical and experimental data for a multi-pass submerged arc weld of a balanced double-vee groove weld are presented. The analytical results were obtained using two mathematical approaches. The first approach used was quasi-linear approach identified as the Shrinkage Force Method. This method utilizes estimates of the cooldown forces in the weld region due to weld deposit and subsequent remelt, to predict distortion. The second approach employs a full nonlinear thermoplastic analysis to predict distortions and residual stresses. Several different mathematical models were employed in the study and the results obtained are compared with experimentaldata. (Stoehr)
