Abstract: Rivers ships are complex welded structures, built of specific volume sections. Each volume section contains tens or hundreds of nodes, characterized by high restraint conditions. Due to the welding process, each node experiences local concentration of stresses. The paper aims to present a double, analytical and practical, evaluation of the residual stresses in a part of the double bottom deck. It has been built a physical model of such part of the double bottom deck and welding process was applied. The displacement was measured and the residual stress was obtained. It has been concluded that each new welding pass produced lower shrinkage than the previous one. A similar geometrical model was defined and simulated in FEM software. The results confirmed the results of the practical tests. It was, also, found that the cooling between the welding passes produced sudden variations of the displacements, all being in the sense of reducing the opening of the groove.
