A procedure was developed for nondestructive evaluation of residual stresses in welded joints based on application of high-density current pulses and laser speckle-interferometry. Comparison of the results of residual stress measurement in welded joints, obtained by the developed method and by hole-drilling method, was performed. 19 Ref., 10 Fig.
