“…The high sensitivity of the AE testing method to the microstructure parameters reveals a great variety of changes in the material structure and composition. For example, in [18,19], the authors implemented AE to identify such microscopic AE sources as the destruction of carbide particles in high-strength steels. In [20], the authors studied martensitic transformations in steel with an austenitic structure, AISI 304.…”

In this study, we investigated defect detection in dissimilar welded joints by the acoustic emission (AE) method. The study objects were carbide and decarburized interlayers, which are formed at the fusion boundary between austenitic and pearlitic steels. Diffusion interlayers, as a structural defect, usually have microscopic dimensions and cannot be detected using conventional non-destructive testing (NDT) methods. In this regard, the AE method is a promising approach to diagnose metal objects with a complex structure and to detect microscopic defects. In this paper, the AE signatures obtained from testing defect-free specimens and specimens with diffusion interlayers are analyzed. We found that the AE signature for defective and defect-free welded joints has significant differences, which makes it possible to identify descriptors corresponding to the presence of diffusion interlayers in dissimilar welded joints.

“…NDT techniques [ 5 ] include a range of integrity analysis approaches that assess the properties of the material from which the pipeline is made. The most used techniques are: ultrasound testing [ 6 , 7 , 8 ], including phased array ultrasonic testing [ 9 , 10 ]; radiography testing [ 11 , 12 ]; magnetic particle and other flux leakage-based inspections [ 13 ]; approaches based on acoustic emission [ 14 , 15 , 16 ]; hybrid testing methods [ 17 ]; and several other methods.…”

In the field of intelligent surface inspection systems, particular attention is paid to decision making problems, based on data from different sensors. The combination of such data helps to make an intelligent decision. In this research, an approach to intelligent decision making based on a data integration strategy to raise awareness of a controlled object is used. In the following article, this approach is considered in the context of reasonable decisions when detecting defects on the surface of welds that arise after the metal pipe welding processes. The main data types were RGB, RGB-D images, and acoustic emission signals. The fusion of such multimodality data, which mimics the eyes and ears of an experienced person through computer vision and digital signal processing, provides more concrete and meaningful information for intelligent decision making. The main results of this study include an overview of the architecture of the system with a detailed description of its parts, methods for acquiring data from various sensors, pseudocodes for data processing algorithms, and an approach to data fusion meant to improve the efficiency of decision making in detecting defects on the surface of various materials.
