Industrial Radiography

Radiography is a procedure that helps to see objects that cannot be seen with naked eye. The use of electromagnetic radiation helps to view these objects without any hindrance. The concept of Radiography came into existence in 1895 when X-rays were discovered. Radiography soon became widely applicable in various areas for testing and inspection. Today, Industrial Radiography has become an integral part of nondestructive testing (NDT). The electromagnetic radiations penetrate deep into the object and help to inspect it from inside. The technology allows identifying the hidden flaws, and rectifying them at early stage.

Use of Industrial Radiography for Inspection of materials

Industrial Radiography is being widely used for testing and grading of welds of equipments to ensure their quality. It is used to carry out welding inspection in various areas and check the welds on pressurized piping, pressure vessels, high-capacity storage containers, pipelines, and other structural welds. While conducting a welding Inspection with radiography, it is advisable to inspect the component for any external defects. It is very difficult to inspect an irregular welded surface and identify internal defects.

Industrial Radiography can be used to inspect any flat or solid material, such as walls and floorings. It allows testing concrete and locating rebar or conduit and also inspecting pipewalls against anomalies that are caused because of corrosion and mechanical damages. Industrial Radiography is one of the most essential methodologies to maintain high quality standards and carry out welding inspection efficiently and effectively. 

Industrial Radiography Equipment

Radiography (X-ray) or high energy X-ray machines are used in Industrial Radiography. These machines generate a radiograph of the object and show internal and external defects. The radiograph is generated in variations of black, white and gray. These state-of-the-art machines also help to check the thickness variations and assembly details of inspected object. They are widely used in welding inspections and carry out the welding operations successfully.

Industrial Radiography Safety Precautions

Industrial Radiography is a critical task and involves use of high energy radiations and gamma rays; therefore, it is very important to take safety precautions for the people using this technology. Some of the safety tools used in Industrial Radiography inspections are radiation survey meter an alarming dosimeter, a gas-charged dosimeter, and a film badge or thermo-luminescent dosimeter (TLD). Use of these safety devices help to protect the radiographer against the injuries that can be caused due to overexposure to radioactive rays
