Abstract
Oppfinnelsen angår en fremgangsmåte og anordning for ikke-destruktiv testing av detaljer, maskinenheter og mekanismer, forskjellige materialer, and særlig en fremgangsmåte og anordning for ikke-destruktiv bestemmelse av egenspenninger som er basert på den optiske holografiske interferometriteknikken. Først registreres et hologram av undersøkelsesområdet av objektet i sin starttilstand. Deretter gjennomføres frigjøringen av egenspenningene i et undersøkelses-punkt i undersøkelsesområdet ved eksponering av overflaten av objektet til en høy-strøm elektrisk puls med rektangulær form. Til slutt lages et interferogram av det nøyaktig samme området av objektet, og egenspenningene ved undersøkelsesområdet bestemmes fra formen og størrelsen av kantene i interferogrammet.The invention relates to a method and apparatus for non-destructive testing of details, machine units and mechanisms, various materials, and more particularly to a method and apparatus for non-destructive determination of intrinsic voltages based on the optical holographic interferometry technique. First, a hologram of the examination area of the object in its initial state is registered. Thereafter, the release of the natural voltages at an examination point in the examination area is effected by exposing the surface of the object to a high-current electrical pulse of rectangular shape. Finally, an interferogram is made of the exact same area of the object, and the intrinsic stresses at the examination area are determined from the shape and size of the edges of the interferogram.
