For this inspection, a 5" OD pipe with a 0.380" wall thickness was used. The pipe contained several 1.6 mm (0.06") diameter holes distributed along its length.
The first hole was located 2.6' away, while the farthest hole was at a distance of 5.3'. The test was conducted using guided waves with MRUT-SH technique VOLTA 2 successfully detected the holes clearly, despite their challenging locations.
La técnica MRUT-SH es una técnica de ondas guiadas que emplea ondas transversales horizontales (SH). Las ondas SH son generadas por medio de la magnetostricción, a partir de la aplicación de una banda magnetostrictiva. Puesto que el mismo sensor se utiliza tanto para transmitir como recibir (ej. Modo Pulso-Eco), el sensor detectará reflexiones desde los defectos en el material.
