What is the primary consequence of an improper interface assessment during testing?

The primary consequence of an improper interface assessment during testing is the misinterpretation of the actual material quality. In phased array testing, evaluating interfaces is crucial because they can significantly influence the performance of the test and the results obtained. If the interface is not assessed accurately, it may lead to a misunderstanding of the material's integrity or defect characterization. Misjudging the interface can mask the presence of actual flaws or, conversely, suggest flaws where none exist, affecting the reliability of the inspection results.

It is essential to recognize that interface conditions, such as bonding or surface characteristics, directly impact the ultrasonic wave propagation. A failure to accurately evaluate these factors can result in misleading conclusions about the overall quality and fitness of the material being inspected, which can have serious implications in applications where safety and reliability are paramount.
