Abstract
Static strength of welded joints comprising a less strong weld on plates with X-groove, compared with base metal, has been estimated by the method of solving the plane problem of the plasticity theory. The stressed state of mechanically inhomogeneous butt welded joints has been studied. The possibility of determining the optimal geometric size of the weld metal is shown.
Keywords: butt welded joints, relative thickness, soft interlayer, gap, weld root, bevel angle, welded edges, limit tensile force, local strengthening, mechanical inhomogeneity, inhomogeneity coefficient
