Radiography-Testing
Radiography is a method of inspecting materials for seeing hidden flaws by using the ability of short X-rays, gamma rays and neutrons to penetrate various materials. It is a major element of non-destructive testing. radiography for non-destructive testing is used to inspect, among others, concrete and a wide variety of welds, such as those in gas and water pipelines, storage tanks and structural elements.
It can identify cracks or flaws that may not be otherwise visible. These characteristics have made non-destructive testing a key tool for quality control, safety and reliability.
