We propose a method for the determination of the triaxial stressed state in the process of butt welding by a rapidly moving heat source and construct three-dimensional distributions of the components of the stress field for welded joints of 1201-Т aluminum alloy with different thicknesses made by the electronbeam welding. It is shown that the residual transverse σ xx and axial σ yy stresses are maximum and constitute 80–90% of the ultimate strength of the metal. It is shown that, for plates of smaller thickness, the residual stresses are higher due the smaller sizes of the heat-and-deformation affected zone.
