NOTES: 1. For hardfacing, all requirements of figure 7-6 shall be met, except that the location of hardness testing and macro-etch specimens, and additional base metal diameter requirements, shall be per this figure. For 5G and 6G welds where uphill progression welding on the first layer occurs on at least one segment (i.e., 9 o’clock, 3 o’clock, or both), perform the hardness test on one of the uphill segments at 9 o’clock or 3 o’clock. 2. For clad welding, all requirements of figure 7-4 shall be met, except that the location of side bends, macro-etch specimens, and composition testing, and additional base metal diameter requirements, shall be per this figure. For 5G or 6G position welds where uphill progression welding on the first layer occurs on at least one segment (i.e., 9 o’clock and/or 3 o’clock), perform composition testing on one of the uphill segments at 9 o’clock or 3 o’clock (also see note 4(b)(i) for extra tests where OD exceeds 5 inches).
