Classification of methods of reduction of strain of welded joint is executed on a source of power influence. It is revealed the factors promoting perfection dislocation of structure. Physical and mathematical models for the description of the dynamics of stress-deformed state of welded joints are chosen at influence on them of pulse loading. The algorithm of numerical realization of mathematical model is developed. It is shown, that pulse action under certain conditions allows transferring stretching pressure in compressing as it takes place at welding stress relaxation.5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
