X Ray Radiography - Non Destructive Testing - Metrology and Quality Engineering

TL;DR

X-Ray radiography is used to detect internal defects in materials by generating penetrating radiation that creates latent images on photographic films.

Transcript

hello students today we will discuss one more ndt method that is x-ray radiography so first of all introduction to x-ray radiography so this technique is suitable for detection of internal defects in ferrous non-ferrous and any other material so x-ray radiography can be used in any type of material for detection of defects so this technique is suit...

Questions & Answers

Q: How does X-ray radiography detect internal defects in materials?

X-ray radiography generates penetrating radiation that is absorbed differentially by materials, creating latent images on films to visually detect defects.

Q: What are the advantages of using X-ray radiography in non-destructive testing?

X-ray radiography provides pictorial information, permanent records, and sensitivity for thin sections, making it suitable for various materials.

Q: What are the disadvantages of X-ray radiography in non-destructive testing?

X-ray radiography may not be suitable for very thick materials, poses health hazards with prolonged exposure, and requires accurate beam direction for defect detection.

Q: Why is X-ray radiography not suitable for surface defect detection?

X-ray radiography does not indicate the depth of defects below the surface and is not designed for automation, making it challenging to detect surface defects accurately.

Summary & Key Takeaways

• X-Ray radiography is a non-destructive testing method suitable for detecting defects in various materials.

• X-Rays, electrically generated, penetrate materials and create latent images on films.

• The method requires film packages, radiation monitors, and processing chemicals for accurate defect detection.
