API QUSE - Qualification of Ultrasonic Testing Examiners (Sizing) is a certification developed and offered by the American Petroleum Institute through their Individual Certification Program to help define the minimum criteria for assessing the performance of ultrasonic testing (UT) technicians. To qualify, applicants must possess a current or previous certification in ASNT UT Level II, Level III, or equivalent.
Fitness-for-Service (FFS) assessments and Risk-Based Inspection (RBI) calculations rely heavily on high quality and accurate UT data. Therefore it is important for companies to have confidence in the technicians they employ to collect this data. API's QUSE certification helps inspection companies and owner-users verify that their technicians are qualified to perform UT.
The QUSE certification exam covers equipment and sizing evaluation techniques for crack height sizing. The designed procedure provides guidelines and techniques for ultrasonic sizing of planar cracks which originate at the opposite side of the scanning surface or the inside diameter. This procedure is applicable to carbon steel material thicknesses from 0.375 inches to 1.0 inches. Applicants will be expected to detect flaws, position them with respect to the weld, identify and sketch the flaw position within the weld.
API QUSE certifications are valid for 3 year terms, at which point recertification is required.
