Abstract

In a process for ultrasonic testing of elongated, prism-shaped sections (22) with at least one planar outer surface (54) extending along the longitudinal axis (26) of the section, with the objective of detecting material defects or verifying geometric data, the section (22) to be tested is exposed to ultrasonic beams from several ultrasonic probes (28 to 34) installed in a probe carrier (44). The section (22) is moved along its longitudinal axis (26) in relation to the probe carrier (44). The latter is installed in the rotor (20) of a rotary testing machine which rotates around the longitudinal axis (26) of the section (22). The probes (28 to 34) are installed in the probe carrier (44) so that each can be displaced individually, either transversely or, preferably, at right angles to the longitudinal axis (26) if the section (22) and the direction of the probes and/or so that their angular position can be adjusted individually by swivelling them around a swivel axis ( 58) running parallel to the longitudinal axis (26) of the section (22). The individual probes (28 to 34) are adjusted so that the central beams (46) emitted by each probe (28 to 34 ) impinge upon the planar outer surfa…
