This publication outlines the general guidelines for the development of owner/user ultrasonic examiner qualifcation programs that are consistent with API performance demonstration programs for detection, characterization, and crack height sizing of weld discontinuities in weldments. The performance demonstration programs covered in this publication include the following:
1.1.1 Qualifcation of Ultrasonic Testing Examiners for Detection and Characterization of Flaws Using Manual Angle Beam Testing: QUTE QUTE exam description: Exam candidates use manual ultrasonic faw-detection instruments to examine new construction carbon steel pipe and plate welds manufactured to ASME code requirements. Candidate performance measures include faw detection, characterization, length sizing, and false calls.
1.1.2 Qualifcation of Ultrasonic Testing Examiners for Detection and Characterization of Flaws Using Manual UT-Phased Array: QUPA
QUPA exam description: Exam candidates use manual ultrasonic phased array instrumentation to examine new construction carbon steel pipe and plate welds manufactured to ASME code requirements. Candidate performance measures include faw detection, characterization, length sizing, and false calls.
1.1.3 Qualifcation of Ultrasonic Testing Examiners for Manual UT-Angle Beam Crack Sizing: QUSE QUSE exam description: Exam candidates use manual ultrasonic faw detector instrumentation to size opposite side cracking in new construction carbon steel plate welds with and without weld crowns in place.
1.1.4 Qualifcation of Ultrasonic Testing Examiners for Manual UT-Phased Array Crack Sizing: QUSE-PA QUSE-PA exam description: Exam candidates use manual ultrasonic phased array instrumentation to size opposite side cracking in new construction carbon steel plate welds with and without weld crowns in place.
1.2 Weld specimens for the QUTE, QUPA, QUSE, and QUSE-PA exams are single- or double-bevel carbon steel plate or pipe welds 0.50 in.–1.00 in. (12.5 mm–25 mm) in thickness. See Section 4 for specimen details.
