Popis:	The paper discusses the features of elastic-plastic transition in welded joints of Mn- Si steel samples made by stationary arc welding consumable electrodes to assess the possibility of exploitation of such compounds after the stress tests. In welded joints made by a stationary arc, the elastoplastic transition is realized by initiating the Chernov-Lüders band in the weld metal, followed by the formation of moving fronts in heat-affected zones. Local internal stresses in the heat-affected zones of welded joints made by a stationary arc are at the level of the material strength, therefore, the generation of the Chernov-Lüders bands occurs as relaxation processes.
