Abstract
1. Способ снижения остаточных напряжений сварных соединений металлических конструкций, включающий электрофизическую обработку участков шва и зоны термического влияния, отличающийся тем, что в процессе выполнения сварки через нагретый электродуговой сваркой участок шва и зоны термического влияния пропускают знакопеременные импульсы электрического тока длительностью (2,0±0,5) с и паузой между импульсами 1-3 с.2. Способ снижения остаточных напряжений по п.1, отличающийся тем, что импульсы электрического тока пропускают перпендикулярно сварному шву.3. Способ снижения остаточных напряжений по п.1, отличающийся тем, что импульсы тока пропускают в зоне остывания шва, где температура металла меньше температуры точки Кюри на 50-100 градусов по шкале Цельсия.1. A method of reducing the residual stresses of welded joints of metal structures, including the electrophysical treatment of the weld sections and the heat-affected zone, characterized in that alternating electric current pulses of duration (2.0 ± 2) are passed through the heated weld portion of the weld and heat-affected zone during welding. 0.5) s and a pause between pulses 1-3 s. 2. A method for reducing residual stresses according to claim 1, characterized in that the electric current pulses are transmitted perpendicular to the weld. The method of reducing residual stresses according to claim 1, characterized in that the current pulses are passed in the weld cooling zone, where the metal temperature is 50-100 degrees Celsius below the Curie point temperature.
