Popis:	The paper presents a formation of residual stresses near the weld-affected zone. It is shown that the residual stress values depend on load application and the type of weld joints. The proprietary know-how is suggested for the analysis of stress and strain state using measurement of the ultrasound velocity in weld joints under load. A correlation between effective and residual stresses is shown when testing the bridge crossing over the river Tom (Tomsk, Russia). A method of reducing these stresses using the ultrasonic impact treatment is suggested herein.
