STUDY OF RESIDUAL STRESSES IN REPAIR BUTT WELD

2015-11-05_09h53_39Welding is one of the most important assembling methods which are widely applied in different applications. In service conditions, some of the weld joints which meet defects must be repaired. The residual stresses impress the operation and efficiency of the repair weldment. In this study, the temperature and the residual stress fields were investigated by both the finite element simulation and the experimental measurement due to repair butt weld of the two thin St 37 plates….. The experimental results revealed that the finite element simulations obtained in the present work were capable of predicting the residual stresses in the initial and repair welds. Read more ……
