Non-Destructive Testing (NDT), also known as Non-Destructive Inspection (NDI) or Non-Destructive Evaluation (NDE), is a critical process in aerospace, manufacturing, and industrial sectors. It ensures the structural integrity of components without causing any damage, making it an essential practice for quality control, safety assurance, and preventive maintenance . High-quality illustration of a technician performing Non-Destructive Testing (NDT) on an aircraft component using advanced inspection tools, emphasizing precision and safety in aerospace inspections. Types of Non-Destructive Testing Methods 1. Visual Inspection (VT) The simplest and most common method. Uses tools like borescopes, magnifying glasses, and drones for in-depth visual analysis. Helps detect surface cracks, corrosion, and misalignments. 2. Ultrasonic Testing (UT) Uses high-frequency sound waves to detect internal flaws. Ideal for inspecting welds, composite materials, and thick metal structures . Provides real-tim...
