Abstract

This paper presents the results of the research aiming at the evaluation of the influence of various post-weld fatigue improvement techniques on the fatigue limit and life of welded joints in mid- and high-strength steels. It has been demonstrated that the ultrasonic impact treatment (UIT) method is the most efficient fatigue improvement technique that at the same time makes it possible to take advantage of high-strength steels in fabrication of welded structures operating under variable loading.
