Method for ultrasonic inspection of a workpiece in a curvilinear area of its surface and appropriate test assembly for applying the method

摘要

The method involves combining a number of transducer elements into a group and number of examining documents within these test cycles are actuated among each other. The transmitted ultrasonic rays (30a-d) are swiveled in a given angle in this test cycle, so that from each group a number of the examining documents corresponding to the number of the echo signals are received from different directions of the workpiece (2) An independent claim is also included for the testing arrangement.
