Abstract

Способ снижения уровня растягивающих остаточных сварочных напряжений с помощью ультразвуковой ударной обработки сварных соединений стыков труб, отличающийся тем, что обработка сварных соединений стыков труб производится с внутренней стороны стенки трубы, с шириной обработки от 30 до 80 мм, так как в процессе сварки высокие растягивающие напряжения возникают именно во внутренних поверхностных слоях, в зоне корневого шва. A method of reducing the level of tensile residual welding stresses using ultrasonic shock treatment of welded joints of pipe joints, characterized in that the processing of welded joints of pipe joints is carried out from the inner side of the pipe wall, with a processing width of 30 to 80 mm, since during the welding process there are high tensile stresses arise precisely in the inner surface layers, in the zone of the root seam.
