How does increasing UT range affect A-scan acquisition?

When the ultrasound testing (UT) range is increased, it can lead to prolonged acquisition times due to the increased volume of material that needs to be evaluated. This occurs because a longer scanning range means that the probe has to cover more distance, thereby requiring more time to complete the necessary scans at various angles and positions.

Moreover, as the range increases, each individual pulse takes longer to travel through the material and return to the sensor, which can also contribute to longer setup and data acquisition times. Consequently, A-scan acquisitions will require more extensive processing and time to gather and analyze data, directly affecting the efficiency of the testing process.

In this context, while extending the UT range may provide broader coverage of the component being tested, it doesn't necessarily enhance defect detection speed and can potentially lead to inefficiencies in the workflow during inspections.
