The paper summarizes the study’s results of welded joints fatigue failure obtained by arc welding with controlled and uncontrolled heat input and shock-mechanical treatment. Based on energy parameters of the mode fixed in welding process of samples obtained at various technologies, the experiments on determination of their fatigue life were performed. The results of numerical estimation of fatigue failure of welded joints made of 09G2S steel are presented. The positive influence of shock-mechanical treatment on test samples durability is shown.
