Effect of edge preparation and the distribution of residual stresses and strains in welded joints in dissimilar steels

Numerical methods are used to investigate the changes in the thermomechanical state of the region of the welded joint in dissimilar steels in a wide temperature range. The effect of edge preparation of the welded joint on the formation of residual stresses and strains in the welded joint in two-laye...

Description
Summary:Numerical methods are used to investigate the changes in the thermomechanical state of the region of the welded joint in dissimilar steels in a wide temperature range. The effect of edge preparation of the welded joint on the formation of residual stresses and strains in the welded joint in two-layer steels with different physical-mechanical and service properties is investigated. The calculation results are in agreement with the experimental data.
