Plug Valve Surface Defects Identification through Nondestructive Testing and Fuzzy Deep‐Learning Algorithm for Metal Porosity and Surface Evaluation

Journal of Engineering, Volume 2023, Issue 1, 2023., 2023
This paper addresses the detection and identification of flaws in Plug valves. The Plug valve thermal image is acquired using a Fluke thermal camera [TiS20]. Thermal images of the Plug valve are used for the identification of flaws such as Crack, Porosity, Corrosion, and Internal defects. The thermal images detect the surface flaws and never subsurface

Investigating the Influence of Design Frequency on the Ultrasonic Signal of PFSV‐EMATs

Journal of Sensors, Volume 2022, Issue 1, 2022., 2022
The point‐focusing shear vertical wave electromagnetic acoustic transducer (PFSV‐EMAT) with a concentric meander line (CML) coil has been developed to detect and size micro defection concealed within a certain depth of materials. It is proved to be sensitive to the design frequency, which is associated with the spacing of CML coil.
