Q

Which of the nondestructive testing methods listed, is most often used to accurately detect external defects in welded metals?

🔍 Key Concepts

• Surface vs. internal defects in weld inspection • How dye penetrant, magnetic particle, and ultrasonic testing each works in simple terms • Which methods are best suited for surface (external) flaws vs. internal flaws

💭 Think About

• Think about which method is primarily designed to make very small, open-to-the-surface cracks show up clearly. • Consider which method is mainly used for finding internal defects deep inside the metal, not just at the surface. • Ask yourself: does any single method clearly match “external defects,” or do all methods truly apply equally well to that task?

✅ Before You Answer

• Verify which methods require the defect to be open to the surface to work properly. • Check which method is most commonly described as ideal for surface-breaking cracks in welds. • Confirm whether ultrasonics is mainly associated with internal volumetric flaws rather than just external ones.
