description: Hydrogen in the weldments of high strength steels continues to seriously limit the performance of the components and confounds the quantitative component prognosis. The master's work analyzes domestic and foreign literature on existing models of hydrogen diffusion in welding without traps and taking into account traps, the effect of hydrogen on the mechanical properties of steel, the effect of hydrogen on the properties of welded joints, the formation of cold cracks, and the diffusion and solubility of hydrogen in steels and the influence of hydrogen traps to control diffusion hydrogen in welding high-strength steel were studied. A physical model and a mathematical model of hydrogen diffusion without traps and taking into account traps for a homogeneous and heterogeneous welded joint are described, a program for calculating hydrogen diffusion by the analytical method and the finite difference method is developed, studying the influence of the stress state of the metal, the influence of the temperature gradient, the influence of the initial temperature, the influence of the plate thickness, and the study of traps in the effective diffusion coefficient.
