The results of investigations of hydrogen behavior in process of aging of welded structures of different materials were analyzed. Gradation of the processes taking place in metal at aging was carried out and reasons of reduction of crack resistances in welded joints at room temperature were found. The mechanism was proposed, which explains spontaneous hydrogen emission from metal in process of aging, reasons and consequences of these processes. 22 Ref., 2 Tabl., 11 Fig.
