Numerical analysis of the influence of welding speed on cylindrical pressure vessels

Resumo

This work aims to determine the residual stresses of cylindrical pressure vessels subjected to weld
repairs via numerical analysis . In welding repair , a glove is attached to the pressure vessel through two
longitudinal welds and two circumferential welds . Was performa modeling of the pressure vessels , 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 regions of the weld to verify the behavior of the results after the
cooling period by the Finite Element Method .
