What is the purpose of the scan-plan in PAUT?

The scan-plan in Phased Array Ultrasonic Testing (PAUT) serves a crucial role in detailing how the inspection will be performed. It is specifically designed to indicate the probe position, the movement of the probe during the scan, the angles at which the ultrasound will be emitted and received, and the volume of material that will be covered during the inspection process. This comprehensive overview allows technicians to verify that they are effectively inspecting all necessary areas of the component being tested while ensuring optimal coverage for defect detection.

By clearly defining these parameters, the scan-plan helps to enhance the consistency and effectiveness of the inspection, allowing for accurate and reliable results. It is essentially the roadmap for the PAUT process, guiding the technician through the scanning procedure to ensure nothing is overlooked.
