Table 7-6. Welding Procedure Qualification Material Thickness and Diameter Limits 1/, 2/, 4/, 7/, 8/, 9/, 10/, 11/, 12/ - Continued
NOTES (continued):
13/ For robotic, automatic, or mechanized welding of pipe groove and socket joints, the following shall apply (see 4-4.1.10.1 and 4-7.1.b): (a) Maximum thickness and OD qualified is T and the OD welded or, if OD is 5 inches or greater and wall thickness is 3/8 inch or greater, the following shall apply:
(1) 1.1T and all ODs 5 inches and greater, except as specified for (2). (2) For 1G and 1F welds, 2T, and all ODs 5 inches and greater.
(b) Minimum thickness and OD qualified is T and the OD welded for ODs less than 5 inches or T less than 3/8 inch, and for a welded OD/T combination exceeding 5 inches and 3/8 inch, 5 inches OD and 3/8 inch thickness shall be the minimum qualified. (c) Welding of a small pipe and a large pipe shall qualify thicknesses and ODs in between. (d) For certain flat position welds per 4-4.1.10.1.1, the limits of (a) and (b) above do not apply and the rest of this table shall govern; for example, a 1.5-inch OD, 0.10-inch wall 2G test weld qualifies as follows: (1) Thicknesses of 0.058 – 0.20 inch for flat position longitudinal pipe welds 2-7/8 inch OD and greater, and flat position pipe girth welds over 24 inches OD, and (2) 0.10-inch thickness and 1.5 inch OD for 2G welds and flat longitudinal or girth welds. 14/ Diameter limits for cladding and hardfacing of cylindrical products shall be per table 7-4, footnote 7(a)(2) and figure 7-5, note 4. 15/ For base materials requiring toughness testing by table 7-7, footnote 2 (including thicknesses 0.058 to 1/2 inch), minimum base metal thickness qualified shall be T or 5/8 inch, whichever is less, except that, where T is less than ¼ inch, minimum qualified thickness shall be 1/2T or 0.058 inch, whichever is greater. These limits do not apply to S-11A, S-11C, and S-11D materials, or where PWHT is above the upper transformation temperature (or when an austenitic or S-10H material is solution annealed).
