Abstract
Methods of non-destructive quality control and determination of stress-strain state and residual stresses of welded joints and structures using electron shearography and speckle-interferometry were developed. The compact shearography and speckle-interferometry measuring systems have been created allowing examination of welded structures under the conditions of their manufacture and service. Computer systems for processing interferograms and determination of fields of displacements, deformations and stresses are presented
Keywords: electron speckle-interferometry, shearography, non-destructive testing, residual stresses, computer processing
