Q

Which type of weld testing can be used to detect internal flaws?

🔍 Key Concepts

• Difference between surface inspection vs internal/volumetric inspection methods • Basic purpose of radiographic testing (RT), magnetic particle testing (MT), and dye penetrant testing (PT) • Which methods require access to only the surface, and which can see inside the material

💭 Think About

• Ask yourself: Which method can "see through" the weld metal, not just examine the outside surface? • Which of these methods relies on magnetism or dye to show cracks that break the surface, and which one produces an image of the interior? • Think about how each method would reveal a flaw that is completely enclosed inside the weld, with no opening to the surface.

✅ Before You Answer

• Identify which options are surface-only tests • Identify which option is a volumetric/internal test • Confirm which method is commonly used to create a picture or film of the internal structure of a weld
