Abstract

On long distances, dangerous products like gaz or petroleum are carried by pipelines. To protect the environment, it is urgently useful to test their weld structures. This paper deals with an application of ultrasonic sensors as a non- destructive testing. This application concerns the classification of planar and non-planar defects in carbon steel plate welds, based on the European standard EN 1713. We present the last step of this classification, which makes the distinction between clustered porosities and rough cracks. At our knowledge, this main problem was not solved at this moment.
