List 3 applications of Digital Radiography and How is it different from Manual Radiography?

2. List 3 applications of Thermal Infrared Testing? 3. Imagine yourself a supervisor for a machine shop. You would like to communicate welding discontinuity for a welder. What kind of NDT principles you need to include in your communication plan? 1. An NDT method known as "digital radiography" (DR) uses digital sensors to take pictures of inside structures for inspection purposes. As an example of how digital radiography varies from manual radiography, consider these three NDT applications: Aerospace Industry: For the inspection of aircraft parts, including engine blades, turbine discs, and landing gear, digital radiography is frequently utilized in the aerospace sector. Due to DR's high- resolution photos, inspectors can more precisely find flaws, including fractures, corrosion, and voids. DR creates images faster than manual radiography, exposes inspectors to less radiation, and simplifies saving and retrieving digital images. Oil and gas sector: Digital radiography is also used to inspect pipelines, tanks, and other crucial parts in the oil and gas sector. Due to DR's high-resolution photos, inspectors can more accurately spot flaws like corrosion, leaks, and obstructions. Manufacturing: For the examination of welds, castings, and other crucial parts, digital radiography is frequently employed in the manufacturing sector. Thanks to DR's high-resolution photographs, inspectors can more precisely identify flaws, including porosity, cracks, and incomplete fusion. In conclusion, digital radiography is a cutting-edge NDT method with several benefits over manual radiography. These benefits include quicker image processing, better image resolution, less radiation exposure, and more straightforward digital image storage and retrieval. In numerous applications, digital radiography is used in the manufacturing, oil & gas, and aerospace sectors to provide high- quality images that enable more precise inspection and flaw detection. 2.A non-destructive testing method called thermal infrared testing (TIR) employs the detection of infrared radiation emitted from a surface to pinpoint potential issues. These are three typical uses for TIR: Inspections in Buildings : TIR is used in building inspections to find electrical problems, air leaks, moisture, and inadequate insulation. The method helps to spot temperature variations on a building's surface that signify heat loss, which can be linked to the issue's root. Inspections in the industrial setting: TIR is used to find flaws in machinery, including motors, boilers, and pipes. The method helps in spotting hot spots that might be signs of corrosion, wear or other issues like overheating. Medical Diagnostics: TIR is used in medical diagnostics to identify diseased or inflamed regions, including breast cancer. This method helps in detecting temperature changes between healthy and diseased tissue, allowing the problem's exact location to be determined.

3.To convey welding discontinuity to a welder as a machine shop supervisor, I would need to incorporate the following Non-Destructive Testing (NDT) principles into my communication strategy: Visual Inspection: The simplest type of NDT is visual inspection, which entails inspecting the weld for flaws such as undercutting, porosity, and surface fractures. I would give the welder instructions to evaluate the weld and note any defects visually. Radiographic Testing : X-rays or gamma rays are used in radiographic testing (RT) to provide an image of the weld. I would explain RT to the welder and give them instructions to run this test on the weld to look for internal flaws, such as fractures or a lack of fusion. Ultrasonic Testing (UT): This method uses high-frequency sound waves to examine the weld for flaws or imperfections. I would inform the welder of UT and request that they use it to find any subsurface flaws or discontinuities. Magnetic Particle Testing: Iron particles are applied to the surface, and the weld is magnetized in the magnetic particle testing (MT) method. Any locations where the magnetic field is warped because of a crack or another flaw will see an accumulation of particles. I would explain MT to the welder and request that they run this test on the weld to look for any surface or subsurface flaws. Overall, I can assist the welder in identifying welding discontinuity and taking corrective action to guarantee that the weld complies with the necessary quality requirements by including these NDT principles in my communication plan.
