Abstract
An arrangement in which at least one ultrasonic sensor is coupled to an article to be tested by a liquid coupling medium in an automatic ultrasonic testing of strips, sheets, and pipes that follow each other as individual pieces. The sensor is positioned along a testing path at a constant distance away from the article by a holder. The sensor has a sound emisson surface, and at least one separate free jet of coupling medium is positioned at a side of the sensor in a plane crossing the testing path. The free jet intercepts a central axis of the sound emission surface, and a layer of coupling medium is formed between the sound emission surface and the surface of the article. Testing of the article includes interior regions covered by all surfaces of the article, as well as the end regions and edges of the article.
