3 (3) The requirements of Section V, Article 2, T-274.2, are to be used only as a guide for film-based radiography. (4) As an alternative to the radiographic examination requirements above, all welds in which the thinner of the members joined is 1 /4 in. (6 mm) thick and greater may be examined using the ultrasonic (UT) method specified by UW-53(b).

4 (b) Indications revealed by radiography within a weld that exceed the following criteria are unacceptable and therefore are defects. Defects shall be repaired as provided in UW-38, and the repaired area shall be reexamined. In lieu of reexamination by radiography, the repaired weld may be ultrasonically examined in accordance with Mandatory Appendix 12 at the Manufacturer’s option. For material thicknesses in excess of 1 in. (25 mm), the concurrence of the user shall be obtained. This ultrasonic examination shall be noted under Remarks on the Manufacturer’s Data Report Form: (1) any indication characterized as a crack or zone of incomplete fusion or penetration; (2) any other elongated indication on the radiograph which has length greater than: (-a) 1 /4 in. (6 mm) for t up to 3 /4 in. (19 mm) (-b) 1 /3t for t from 3 /4 in. (19 mm) to 21 /4 in. (57 mm) (-c) 3 /4 in. (19 mm) for t over 21 /4 in.

10 Spot radiography in accordance with these rules will not ensure a fabrication product of predetermined quality level throughout. It must be realized that an accepted vessel under these spot radiography rules may still contain defects which might be disclosed on further examination. If all radiographically disclosed weld defects must be eliminated from a vessel, then 100% radiography must be employed.

11 (b) Minimum Extent of Spot Radiographic Examination (1) One spot shall be examined on each vessel for each 50 ft (15 m) increment of weld or fraction thereof for which a joint efficiency from column (b) of Table UW-12 is selected. However, for identical vessels or parts, each with less than 50 ft (15 m) of weld for which a joint efficiency from column (b) of Table UW-12 is selected, 50 ft (15 m) increments of weld may be represented by one spot examination. (2) For each increment of weld to be examined, a sufficient number of spot radiographs shall be taken to examine the welding of each welder or welding operator. Under conditions where two or more welders or welding operators make weld layers in a joint, or on the two sides of a double‐welded butt joint, one spot may represent the work of all welders or welding operators.

12 (3) Each spot examination shall be made as soon as practicable after completion of the increment of weld to be examined. The location of the spot shall be chosen by the Inspector after completion of the increment of welding to be examined, except that when the Inspector has been notified in advance and cannot be present or otherwise make the selection, the Manufacturer may exercise his own judgment in selecting the spots. (4) Radiographs required at specific locations to satisfy the rules of other paragraphs, such as UW-9(d), UW-11(a)(5)(-b), and UW-14(b), shall not be used to satisfy the requirements for spot radiography.

13 (c) Standards for Spot Radiographic Examination. Spot examination by radiography shall be made in accordance with the technique prescribed in UW-51(a). The minimum length of spot radiograph shall be 6 in. (150 mm). Spot radiographs may be retained or be discarded by the Manufacturer after acceptance of the vessel by the Inspector. The acceptability of welds examined by spot radiography shall be judged by the following standards: (1) Welds in which indications are characterized as cracks or zones of incomplete fusion or penetration shall be unacceptable. (2) Welds having indications characterized as slag inclusions or cavities are unacceptable when the indication length exceeds 2 /3t, where t is defined as shown in UW-51(b)(2). For all thicknesses, indications less than 1 /4 in. (6 mm) are acceptable, and indications greater than 3 /4 in. (19 mm) are unacceptable. Multiple aligned indications meeting these acceptance criteria are acceptable when the sum of their longest dimensions indications does not exceed t within a length of 6t (or proportionally for radiographs shorter than 6t), and when the longest length L for each indication is separated by a distance not less than 3L from adjacent indications. (3) Rounded indications are not a factor in the acceptability of welds not required to be fully radiographed UW-52 SPOT EXAMINATION OF WELDED JOINTS (c)

  • 4. 4 (b) Indications revealed by radiography within a weld that exceed the following criteria are unacceptable and therefore are defects. Defects shall be repaired as provided in UW-38, and the repaired area shall be reexamined. In lieu of reexamination by radiography, the repaired weld may be ultrasonically examined in accordance with Mandatory Appendix 12 at the Manufacturer’s option. For material thicknesses in excess of 1 in. (25 mm), the concurrence of the user shall be obtained. This ultrasonic examination shall be noted under Remarks on the Manufacturer’s Data Report Form: (1) any indication characterized as a crack or zone of incomplete fusion or penetration; (2) any other elongated indication on the radiograph which has length greater than: (-a) 1 /4 in.

  • 11. 11 (b) Minimum Extent of Spot Radiographic Examination (1) One spot shall be examined on each vessel for each 50 ft (15 m) increment of weld or fraction thereof for which a joint efficiency from column (b) of Table UW-12 is selected. However, for identical vessels or parts, each with less than 50 ft (15 m) of weld for which a joint efficiency from column (b) of Table UW-12 is selected, 50 ft (15 m) increments of weld may be represented by one spot examination. (2) For each increment of weld to be examined, a sufficient number of spot radiographs shall be taken to examine the welding of each welder or welding operator. Under conditions where two or more welders or welding operators make weld layers in a joint, or on the two sides of a double‐welded butt joint, one spot may represent the work of all welders or welding operators.

The location of the spot shall be chosen by the Inspector after completion of the increment of welding to be examined, except that when the Inspector has been notified in advance and cannot be present or otherwise make the selection, the Manufacturer may exercise his own judgment in selecting the spots. (4) Radiographs required at specific locations to satisfy the rules of other paragraphs, such as UW-9(d), UW-11(a)(5)(-b), and UW-14(b), shall not be used to satisfy the requirements for spot radiography.

  • 13. 13 (c) Standards for Spot Radiographic Examination. Spot examination by radiography shall be made in accordance with the technique prescribed in UW-51(a). The minimum length of spot radiograph shall be 6 in. (150 mm). Spot radiographs may be retained or be discarded by the Manufacturer after acceptance of the vessel by the Inspector. The acceptability of welds examined by spot radiography shall be judged by the following standards: (1) Welds in which indications are characterized as cracks or zones of incomplete fusion or penetration shall be unacceptable. (2) Welds having indications characterized as slag inclusions or cavities are unacceptable when the indication length exceeds 2 /3t, where t is defined as shown in UW-51(b)(2). For all thicknesses, indications less than 1 /4 in. (6 mm) are acceptable, and indications greater than 3 /4 in. (19 mm) are unacceptable. Multiple aligned indications meeting these acceptance criteria are acceptable when the sum of their longest dimensions indications does not exceed t within a length of 6t (or proportionally for radiographs shorter than 6t), and when the longest length L for each indication is separated by a distance not less than 3L from adjacent indications. (3) Rounded indications are not a factor in the acceptability of welds not required to be fully radiographed UW-52 SPOT EXAMINATION OF WELDED JOINTS (c)
