Radiographic inspection, often referred to as industrial radiography or X-ray testing, is a powerful non-destructive testing (NDT) method used to examine the internal structure of materials for flaws, defects, and anomalies. This technique utilizes high-energy electromagnetic radiation, typically X-rays or gamma rays, to penetrate the material being inspected.

How it works:

During radiographic inspection, a radiation source (X-ray machine or a gamma-ray projector) is positioned on one side of the test object, while a film or digital detector is placed on the opposite side. The radiation penetrates the material, and variations in density or thickness result in differences in the amount of radiation reaching the detector. These differences are captured on the film or detected by digital sensors, producing an image that reveals the internal features of the object.

Applications:

Radiographic inspection is widely used across various industries for the evaluation of welds, castings, forgings, pipelines, and other critical components. It is particularly valuable for detecting defects such as cracks, porosity, inclusions, and incomplete fusion within materials. This method is essential in ensuring the structural integrity and safety of components in industries such as aerospace, automotive, oil and gas, manufacturing, and construction.
