How does phased array testing typically compare to radiographic testing?

Phased array testing is recognized for its increased sensitivity to defects when compared to radiographic testing. This is largely due to its ability to focus and steer ultrasound waves, which allows for a more detailed and comprehensive examination of the inspected material. The precise control over the sound beam enables the detection of smaller and more subtle flaws, which could be missed with other methods.

In contrast, radiographic testing typically relies on the absorption of radiation through different materials to reveal defects, which may not capture all defects effectively, particularly if they are small or located in challenging positions. Therefore, the sensitivity of phased array testing gives it a significant advantage in applications where detecting small flaws is crucial. This higher sensitivity enhances the effectiveness of inspections, making it a preferred choice in many critical applications.
