The majority of existing structures contain welded joints. Questions of monitoring service characteristics of welded joints, using acoustic emission method are considered. Attention is given to a change in material properties of operating structures with welded elements after long-term service, taking into account the time and probable violation of service conditions. Examples of evaluation of the change in properties of welded structure materials by the data of acoustic emission, determination of their damage and residual service life, are given. 17 Ref., 5 Tabl., 24 Fig. Keywords: welds, service properties, acoustic emission (AE), AE activity, AE scanning, damage, destruction
