摘要：

The presence of the residual stresses greatly influences the reliability of the welded structure. That is why it is necessary to know the level of these stresses and to reduce them as much as possible. The paper present a method for the evaluation of the residual stresses level in the butt welds of the cylinder type pieces (cylindrical shell). The method was used in order to emphasize the influences of the technological process over the interior stresses that are produced in the cylinder pieces. The obtaining results can be extended to the welded joints of the flat semi-products.
