Radiographic Testing (RT) – Principle, Procedure, Types, Advantages & Applications
Radiographic Testing (RT) is one of the most advanced and reliable Non-Destructive Testing (NDT) methods used to detect internal defects in materials. Widely applied in industries such as oil & gas, aerospace, construction, and manufacturing, RT plays a vital role in ensuring structural integrity and safety. In this blog, we will cover the principle, procedure, types, advantages, and applications of Radiographic Testing , helping you understand this powerful inspection technique in a simple and practical way. 🔍 What is Radiographic Testing (RT)? Radiographic Testing (RT) is a non-destructive testing method that uses X-rays or Gamma rays to examine the internal structure of a component. It helps detect hidden defects such as cracks, porosity, inclusions, voids, and weld defects without damaging the material. The result of RT inspection is usually displayed as an image (radiograph), where variations in thickness and density reveal defects. ⚙️ Principle of Radiographic Testing The p...
