SECTION A-A
NOTES: 1. Test assembly shown is for plate; for cylindrical products, see figure 7-17A. 2. Qualification positions shall be per table 7-9.
3. Base material thickness, T, shall be 1 inch or the minimum thickness to be qualified, whichever is less (see table 7-10). 4. 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. 5. Welds should be made with the maximum size of filler metal suitable for the position of the test plate. 6. Test weld deposited thickness should be approximately equal to the un-machined weld thickness to be deposited in production; number of weld layers deposited shall be per figure 7-17A, note 7(a) (for hardfacing) or note 8(a) (for cladding). 7. Qualified weld thickness and minimum number of weld layers shall be per table 7-10, footnote 16 and figure 7-17A, note 7(a) (for hardfacing) or note 8(a) (for cladding). 8. The entire completed weld surface shall be machined and then VT and PT inspected per 5-4. Machining for hardfacing shall be per figure 7-17A, note 7(a) and, for cladding, figure 7-17A, note 8(a). Acceptance criteria for VT and PT shall be figure 7-6, note 4 for hardfacing or figure 7-4, note 4 for cladding. After NDT, cut, etch, and examine both faces of the macro-etch specimen per 5-4; for hardfacing, perform hardness testing per note 9 below and for cladding, perform composition testing per note 10 below when required. 9. For hardfacing, perform hardness testing by taking three evenly spaced hardness readings on the machined surface and following requirements of figure 7-17A for testing, acceptance criteria, and the allowance for retesting. 10. For cladding, where both criteria of figure 7-17A, note 8(a)(ii) are met, perform one composition test at a location near the end and center-width of the weld. The thickness and weld layer at which composition is obtained, and testing and acceptance criteria, shall be per figure 7-17A, notes 8(a)(ii) and 8(c). Figure 17.
