Abstract

The method of ultrasonic inspection of welds of articles, wherein planes (3, 8) of polarization of transverse ultrasonic oscillations radiated into a weld (4) of an article (2) and of these oscillations registered upon their reflection by the reflecting surface of a flaw (6) of the weld (4) are set relative to each other at an angle 2.delta., an angle .xi..sub.1 between the plane (3) of polarization and a plane (5) of incidence of ultrasonic oscillations upon the reflecting surface and an angle .xi..sub.2 between the plane (8) of polarization and the plane (5) of incidence being selected substantially equal to 70.degree., thus providing for extracting from the radiated ultrasonic oscillations their component polarized horizontally with respect to the reflecting surface of the flaw (6), the amplitude of which is employed to estimate the geometrical parameters of the flaw (6), while the time of its registration is used to estimate the location of the flaw (6) in the weld (4).
