We justify the efficiency of high-frequency mechanical peening for the improvement of the corrosion fatigue characteristics of welded joints and evaluate its influence on the corrosion resistance of the base metal. The cyclic fatigue life of welded butt and T joints of 15KhSND steel in the intact and hardened (by high-frequency mechanical peening) states in air and in a corrosive medium (3% NaCl) at a frequency of 5 Hz is investigated. We use specimens of the base metal after grinding and after grinding with subsequent hardening by high-frequency mechanical peening. It is shown that the procedure of treatment by high-frequency mechanical peening noticeably increases the fatigue characteristics of welded joints both in air and in 3% NaCl. Its influence on the rate of general corrosion of the surface of specimens of the base metal after testing for 1300, 2200, 4700, and 8760 h in distilled water and in 3% NaCl is also established.
