Industry Connect Course – OML351: Industrial Non-Destructive Testing (INDT)
Department of Mechanical Engineering, CARE College of Engineering
The Department of Mechanical Engineering organized an Industry Connect Course on OML351 – Industrial Non-Destructive Testing (INDT) in collaboration with Techie NDT Pvt. Ltd., Trichy. The sessions were conducted by Mr. Madeswaran Nagarajan, Technical Director, Techie NDT Pvt. Ltd., under the coordination of Mr. S. Arun Prakash S, Assistant Professor, Mechanical Engineering.
The program aimed to bridge the gap between classroom learning and industrial practice by providing students with hands-on exposure to modern Non-Destructive Testing (NDT) techniques widely used in manufacturing, aerospace, and power industries.
Session Highlights
1. Liquid Penetrant Testing (LPI) – 07.08.2025
Students explored the principles, applications, and inspection procedures of LPI. They performed complete surface inspection workflows, identifying cracks and defects under both visible and fluorescent light.
Learning Outcome: Ability to perform LPI, interpret indications, and apply quality control procedures in real-world scenarios.
