Final answer:
Electronic scanning in phased array testing is complex and dynamic, as it enables the electronic control of the probe characteristics to inspect various materials and geometries in non-destructive testing applications.
Step-by-step explanation:
In phased array testing, electronic scanning is characterized as B) complex and dynamic. Unlike traditional ultrasonic methods, phased array systems allow the electronic control of the probe characteristics, which includes the beam angle, focal point, and sweep. This modern technique uses multiple ultrasonic elements and electronic time delays to shape and steer the beam, making it highly adaptable to inspecting different types of materials and geometries. This method can be used for flaw detection, sizing, and imaging in non-destructive testing applications.
Phased array systems are commonly used in many industrial sectors such as aerospace, power generation, and oil & gas to ensure the integrity of components without causing damage. The adaptability of phased array technology allows for rapid data acquisition and advanced imaging capabilities which contribute to more effective and reliable inspections.
