摘要：
The ultrasonic impact treatment (UIT) is one of the new and promising processes for fatigue life improvement of welded elements and structures. In industrial application this process is also known as ultrasonic peening (UP). The fatigue testing of welded specimens showed that the UIT/UP is the most efficient improvement treatment as compared with traditional techniques such as grinding, TIG-dressing, heat treatment, hammer peening and laser peening. The description of UIT/UP technology and the results of fatigue testing of welded elements of steels and aluminium alloys in as-welded condition and after application of UIT/UP are discussed in this paper.
