Special Issue Information
Dear Colleagues,
This Special Issue, entitled “Emerging Non-Destructive Testing Technologies: Advances and Applications”, explores the latest innovations in and practical implementations of non-destructive testing (NDT) across various industries. The Issue highlights advancements in multiple NDT techniques, including ultrasonic testing, radiography, eddy current testing, thermography, and computed tomography (CT), which collectively enhance our ability to assess material integrity, identify defects, and ensure quality without causing damage.
The integration of advanced technologies such as machine learning, artificial intelligence, and real-time data analysis is driving NDT forward, allowing for more precise defect detection and comprehensive structural evaluations. These developments are instrumental in sectors such as aerospace, automotive, and manufacturing, where ensuring safety and reliability is paramount.
For example, thermographic NDT, which utilizes infrared imaging to evaluate the thermal properties of materials, continues to evolve. It is particularly effective when detecting porosity, cracks, and fusion defects in additive manufacturing (AM) parts, both online and offline, contributing to improved quality control and reliability. Advances in infrared cameras and data processing algorithms have further expanded its applications.
The combination of thermographic NDT with other technologies, such as ultrasonic testing, radiography, eddy current testing, and computed tomography (CT), strengthens defect detection and material assessment processes. This multi-modal approach ensures a more thorough and accurate evaluation of structural integrity by leveraging the unique strengths of each technique.
This Issue also showcases case studies where NDT technologies, including thermographic methods, have successfully identified surface and subsurface defects, including voids, delamination, porosity, cracks, and other critical issues in real-world scenarios.
In conclusion, this Special Issue offers a comprehensive overview of emerging NDT technologies, underlining their growing role in maintaining the safety, reliability, and efficiency of industrial applications.
