Abstract

This work has how objective the determination cylindrical pressure vessel tests with a weld repair through numerical analysis. In welding repair, a glove is attached to the pressure vessel through two longitudinal welds and two circumferential welds. Was performe modeling of the pressure, the repair and the welds acoording to the standart. The parameters of the weld bead will be adopted on the basis of what happens in practice, and this will be done the analyzes of the residual stresses varying the speed of the weld bead. From this, will be analyzes the residual stresses in the regionsof the weld to verify the behavior of the results after the cooling period by the Finite Element Method.
