Abstract
The paper gives the results of fatigue testing of butt welded joints after high-frequency mechanical peening, allowing for different preparation technologies. It is shown that measuring the depth of the peened zone groove is one of the objective methods for assessment of the efficiency of treatment of the welded joints.
