ENG: The article discusses the theoretical foundations for improving pipe welding processes through the use of vibration. A mathematical model of a pipe welded joint has been constructed, which makes it possible to determine the residual stresses in welded seams exposed to vibration during the welding process and the optimal time of vibration exposure. The constructed mathematical model makes it possible to obtain analytical values of residual stresses for each specific processed object having data on the natural vibration frequency, vibration damping coefficient, amplitude and frequency of the driving force of vibration.
