Abstract [en]

With the ongoing development of materials and manufacturing techniques, new product design opportunities manifest themselves. However, care must be taken when applying techniques and material where there is less inherent knowledge about different parameters’ effect on the integrity of the final component. In conjunction with destructive testing of components, non-destructive evaluation (NDE) provides valuable insight into the manufacturing process reliability, as well as the possibility for subsequent future in-service inspection. Phased array ultrasonic testing (PAUT) facilitates the inspection of complex geometries on a wide set of material. Mathematical modelling of ultrasonic signal facilitates the optimization of inspection procedures by e.g., maximizing the probability of detection (POD) of specific defect types. In this paper, the response from an immersion annular phased array probe is experimentally validated to the output of the simulation software simSUNDT. In order to only validate the probe model (as both transmitter and receiver) a set of well-defined defects are used. The validity of the simulated amplitude response from side-drilled holes at a depth range of 20-115 mm is investigated. A total of 14 SDH holes in one test piece of is used as cases for validation. The results show a good correspondence between simulated and experimental data for the case where the probe is normal to the component surface.

Ultraljudsprovning av komponenter tillverkade med additiva metoder : Mot förbättrad detektering och klassificering av defekter
Abstract [en]

The focus in this work is on the use of ultrasonic testing as a method for inspecting components manufactured through additive manufacturing (AM) processes. The research is rooted in the need for effective non-destructive testingtechniques that can adapt to the unique challenges posed by AM-produced materials, including complex defect geometries and surface conditions.

Ultrasonic testing is a versatile form of non-destructive testing, offering theability to detect internal flaws, such as voids, cracks, and inclusions, with highprecision and in real-time. Unlike many competing methods, ultrasonic testing works on most types of materials. Ultrasonic testing has been applied forinspection purposes for a long time. Now with emerging manufacturing methods, there is a need for evaluation techniques to keep up with this development.New data processing algorithms open up possibilities of extracting more information from the acquired signal.

The thesis provides a review of UT’s capabilities in detecting and classifyingdefects within AM components, with a particular emphasis on the subtletiesintroduced by the layer-by-layer construction method inherent to AM technologies. The work advances development and validation of simulation modelsaimed at predicting the ultrasonic response from manufactured defects. Thesemodels are crucial for understanding the interaction between ultrasound wavesand material anomalies, offering insights into the potential for enhanced defectdetection strategies.

The research also explores the practical case of integrating UT into the quality assurance processes by relying on mathematical simulation rather than experimental data. The findings suggest avenues for the refinement of creation of inspection procedure, including the the use of meta-models to cheaply acquire worst-case scenario defects, to better accommodate the specificities of AM materials.

Abstract [sv]

Den här avhandlingen handlar om ultraljudsprovning av additivt tillverkade metalkomponenter. Ultraljud är en av flera metoder som används för att detektera defekter i komponenter utan att förstöra komponenten i processen. Samlingsnamnet för dessa metoder är oförstörande provning. Oförstörande provning är en viktig pusselbit i samhällets säkerhet då det möjliggör identifiering och utvärdering av potentiella defekter i material, vilket förebygger olyckor och strukturella fel. Vidare är det en viktig del inom hållbar utveckling genom att maximera nyttjandet av komponenter då dessa inte behöver ersättas med ett överdrivet försiktigt underhållsintervall. Ultraljudsprovning fungerar genomatt ultraljud introduceras in i en komponent, varefter en givare registrerar ekon som uppstår när ljudvågorna interagerar med eventuella defekter. Detta möjliggör både lokalisering och storleksbedömning av defekter, t.ex. sprickor, bindfel eller porer.

Resultaten av den här avhandlingen syftar till att ge förutsättningar för att förbättra tolkningen av dessa signaler, dels genom att experimentellt validera simuleringsmodeller, samt tillämpning av dessa modeller för att utveckla en metamodell för att prediktera amplitudsvaret från en mängd defekter inom en viss parameterrymd. Med verktyg som detta kan billigare inspektionsprocedurer möjliggöras genom att man till större del kan förlita sig på simulering av signaler snarare än att skaffa stort underlag med experimentell data.
