Abstract
Methodology, analytical dependences and nomograms for determining area of efficient use of hardening of the 09G2S steel welded joints by high-frequency mechanical peening and estimation of its influence on increase of cyclic working life at double-frequency loading are proposed.
Keywords: arc welding, welded steel structures, doublefrequency loading, welded joints, increase of cyclic working life, high-frequency mechanical peening
