What is a common application of radiographic testing (RT)?

Radiographic testing (RT) is commonly used to detect internal flaws in welds due to its ability to provide a detailed image of the internal structures of materials. This technique utilizes X-rays or gamma rays to penetrate the material and expose a radiographic film or digital detector, revealing any imperfections such as voids, inclusions, cracks, or other discontinuities within welds. These internal flaws can compromise the integrity and performance of a welded joint, making RT an essential method for quality assurance in welding applications, especially in critical infrastructure and components.

While other techniques might assess surface conditions or measure material properties, RT specifically targets the internal characteristics that are crucial for ensuring the reliability and safety of welded structures.
