Abstract
Feasibility of extension of life of operating welded structures, made from tubes, by using the peening treatment of the zone of welding is considered. It is shown that the use of a linear hypothesis of accumulation of the fatigue damage is rightful for the estimation of the full life. Moreover, the peening treatment of welded joints increases the material fatigue strength
Keywords: ultrasonic peening treatment, welded joint, tubular connections, fatigue resistance, fatigue life, life, residual life, fatigue testing
