Sammanfattning

Effective fouling quantification and localization is an unsolved industrial challenge. As in non-destructive evaluation, fouling could be quantified using traditional transducer collars, which also simplify the structure to a ID-system. In this case the radial information of the location of the fouling is lost. We localized different kinds of fouling in a 3D-system using laser-induced point-excitation and non-axisymmetric guided waves to provide experimental input for an AI-based detection algorithm. Results show that only echoes from those paths intersecting the fouling were altered (decreased amplitudes, time of flight shifts). By amalgamating information from several circumferential paths, the fouling can be located in the pipe.
