Abstract

Oggetto della presente invenzione è un dispositivo per l'esame di materiale non distruttivo di oggetti di forma allungata mediante ultrasuoni. Una testa di prova ad ultrasuoni di emissione produce onde ultrasoniche, che attraverso un mezzo di accoppiamento vengono irradiate nel rispettivo oggetto. Almeno tre teste di prova ad ultrasuoni (2, 3, 4) sono disposte in una fila una accanto all'altra lungo una linea (7). Le teste di prova ad ultrasuoni esterne (2, 4) sono teste di prova ad ultrasuoni di ricezione. Le altre teste di prova ad ultrasuoni sono teste di prova ad ultrasuoni di emissione o di emissione/ricezione. La linea (7) è inclinata verso l'asse longitudinale dell'oggetto di un angolo (aD) che sta tra 0° e 45°.
