Program for Field Validation of the Synthetic Aperture Focusing Technique for Ultrasonic Testing (SAFT UT);Analysis Before Test.

摘要

The purpose of the project is to validate the usefulness of SAFT UT for industrial nondestructive evaluations (NDE). SAFT UT is an ultrasonic imaging method for accurate measurement of the spatial location and extent of acoustically reflective surfaces (flaws) contained in objects such as structural components and weldments in nuclear power reactor systems. The increased measurement accuracy offered by SAFT,when compared with that provided by measurement methods now in use,will improve the reliability of flaw severity assessments with resultant safety and economic benefits to the nuclear power industry. To accomplish the objective,SwRI is to design and construct an imaging system,suitable for field use,using the SAFT UT and to conduct sufficient tests with the system to fully characterize its performance and usefulness for the intended purpose. The ultimate goal is to produce a field-rated system for highly accurate flaw size measurements and to conduct sufficient testing of that system to promote its acceptance by industrial and regulatory authorities.
