摘要： The invention relates to a method for the non-destructive ultrasonic testing of a test piece (3) with flat surfaces (5) at an angle to each other by means of several selectively activatable ultrasonic transducers (2, 2′, 2″), whereby the method comprises several test cycles, with which certain (2,2″) of the several ultrasonic transducers (2, 2′,2″) are selected and activated, in order to emit at least one ultrasonic pulse (7, 7″) to the test piece, and with which the ultrasonic pulse reflected in the test piece (3) is received by the selected and/or, if necessary, other ultrasonic transducers (2, 2′, 2″). The method according to the present invention is characterized in that in the respective test cycle, the determined ultrasonic transducers (2, 2″) are so selected and activated, that the main propagation direction (6, 6″) of the ultrasonic pulse (7, 7″) produced by the selected and activated ultrasonic transducers (2, 2″) is perpendicular to at least one of the angled surfaces (5) of the test piece (3). The invention also relates to an associated device and ultilization.
