What is a benefit of using multiple angles in phased array testing?

• A. It reduces the total time required for inspection
• B. It can identify defects that may be missed at a single angle
• C. It primarily serves to enhance the aesthetic of the testing report
• D. It simplifies the data analysis process

Answer: (B)

Using multiple angles in phased array testing is beneficial because it can identify defects that may be missed at a single angle. This multi-angle approach provides a more comprehensive view of the test object by allowing the ultrasonic waves to interact with the material from various directions. Different angles can reveal different types of defects based on their orientation and size. For instance, certain flaws may only be detectable when sound waves approach them from specific angles, while others could be obscured or undetected entirely from just one viewpoint. Therefore, employing multiple angles significantly enhances the likelihood of identifying a wide range of potential defects, leading to more accurate and reliable inspections.
