Abstract
Application of modern method of nondestructive testing (NDT), i.e. electron shearography, for VT20 alloy titanium panels, manufactured with preliminary elastic tension, is considered. The efficiency of application of NDT of titanium panel without dismantling of fixture for tension is shown, thus allowing the immediate elimination of defects, if required.
