  NDA-VT 2026: NDT & E in Dialogue and Application - International Conference at Vel Tech University, Chennai First Announcement and Call for Abstracts Event: NDA-VT 2026 Dates: April 9-10, 2026 Venue: Vel Tech University, Chennai, India   About the Conference NDT & E in Dialogue and Application Vel Tech Rangarajan Dr. Sagunthala R&D Institute of Science and Technology in Chennai, India has placed an increasing attention on Non-Destructive Testing and Evaluation (NDT & E) over the past years. In this context, it established an NDT laboratory named after Dr. Baldev Raj, one of the pioneers of NDT in India, and got NDT spread into the curricula of various of its departments. What Vel Tech intends now is to establish a dialogue with industries and research institutions from outside of its premises to further explore and establish collaborations that allow NDT & E to find a multitude of applications. As such, NDA-VT 2026 invites researchers, academic...

Magnetic particle tests are vital for incoming raw materials that checks for quality and can eliminate the defective ones at earlier stages of manufacturing. Most common steels can be subjected to magnetic particle inspection using electromagnetic yokes, prods, stationery type MPI equipments with circular and longitudinal magnetization testing techniques. MPI tests can eliminate the materials with surface and subsurface flaws. Depth of detecting varies based on magnetic permeability, testing techniques, current used, part geometry, size and other factors. Ideally Magnetic particle inspection-MPI testing techniques can detect flaws up to 0.6" in depth. This NDT method can detect flaws on coated or painted engineering components. Common specifications on magnetic particle testing allows conductive coatings up to 0.1 mm. However maximum thickness of coatings have to be checked with customer specifications or NDT procedures .
