Sammendrag
This research aims to study the characteristics of acoustic emission signals emitted from a steel sample under loading. The thesis is a continuation of previous theses submitted in 2019 by Dawood and in 2020 by Nguyen. Laboratory tests were planned and performed to collect acoustic emission signals from welded specimens and coated specimens. Some of the collected data were processed. Furthermore, different approaches for correlating signals emitted from an event recorded by several channels were discussed, and tools for implementing them was developed in this research.The results provided automated tools to correlate signals of an acoustic emission event captured by many sensors. Also compared the number of hits of the welded and unwelded. Further research on correlating signals from the same source is recommended.
