Abstract
This paper summarises fatigue tests on Y-joints to estimate the influence of a post weld treatment method called Ultrasonic Impact Treatment (UIT). With this method the fatigue resistance could be increased significantly. Furthermore tubular joints of tripods are analysed with numerical simulations to judge these welded joints with the hot-spot-concept. The stress concentration factor for the treated weld toe geometry was determined numerically using submodel analysis. Finally a comparison between welded and cast iron joints is carried out for the fatigue limit state under consideration of experimental results.
