Abstract :
A numerical model is developed to evaluate residual stresses during multi-pass welding of the heterogeneous steels. The model based on the Lagrange´s equation of plasticity and variational principle M. Biot. Plane stress and plane strain quasi-static problems are analyzed for estimate of residual thermal stresses during cooling of the weld.
