Abstract
The effect of electrodynamic treatment (EDT) on the stress-strain state of flat specimens of AMg6 alloy at different diagrams of preliminary loading was studied. The measurement procedure based on ultrasonic NDT method was developed, and residual stresses in butt welded joints were measured. As established, EDT allows residual stresses in AMg6 alloy welded joints to be decreased by 50–65 %.
