Abstract: The scanning device for ultrasonic control of articles comprises a suspension assembly (7) for mounting ultrasonic transducers on a motion mechanism (6) of the scanning device. The assembly (7), in its turn, includes flexible members (8) positioned above a surface (4) of an article (2) under inspection, having ultrasonic transducers (1) fixedly mounted thereon and contained within a housing (3), a beam (9) extending above the flexible members (8) and mechanically connected therewith, two self-aligning supports (10), each including two parts, that is, an arcuate member (16) and rollers (17) so arranged with respect to each other that their relative displacement takes place about a rolling axis (15) common to both supports (10), extending along the surface (4) of the article (2), and two rockers (11) operatively connected to the beam (9) and to the motion mechanism (6).

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).
