We studied the effectiveness of application of high-frequency mechanical peening to improve fatigue resistance characteristics of tee welded joints in metal structures which are operated in a sea climate. Corrosion damage characteristic for such structures after long-term service was produced by soaking the welded joints in KST-1 salt spray chamber for 1200 h. Metallographic studies were conducted of weld zone and HAZ of welded joints in the initial (unstrengthened) state and in the state of strengthening by the HFMP technology after the impact of corrosive environment. It was established that strengthening by this technology does not improve the joint resistance to the impact of neutral salt spray. Fatigue testing of welded joints were performed in the initial and strengthened state after the impact of neutral salt spay. It was found that strengthening tee welded joints by HFMP before the corrosive impact allows increasing their fatigue strength at 2•106
cycles by 48 % and increasing cyclic fatigue life by 2–5 times. 19 Ref., 1 Table, 6 Figures.
