S9074-AQ-GIB-010/248 Rev 1
NOTES: 1. Qualification for cylindrical products shall be performed on pipe or other suitable cylindrical products per table 7-9. Notes 2 through 6 apply to all test welds. Additional requirements for hardfacing and cladding are specified by notes 7 and 8, respectively. 2. T, base material thickness, shall equal the minimum thickness to be qualified per table 7-10. Base material alloy shall match that of a qualified welding procedure for the filler material involved, except that S-1 base material may be used in lieu of S-2 through S-11 materials. 3. Welds should be made with the maximum size of filler metal suitable for the position of the test. 4. For manual and semiautomatic processes, weld test OD vs. production ODs to be welded (in inches) should be as follows: (a) Test an OD < 1 for production welding the OD tested and greater ODs. (b) Test an OD ≥ 1 but < 2 -7/8 for production welding ODs 1 and greater. (c) Test an OD > 2-7/8 for production welding ODs 2-7/8 and greater. For welding operators, the test diameter welded should be within the limits specified by a qualified welding procedure.
