Table 7-7. Welding Procedure Qualification Assembly Test Requirements - Continued
NOTES (continued):
5/ When CVN impact tests are required by footnote 2 above, sets of five impact specimens shall be prepared from the weld metal, sets of three impact specimens shall be prepared from the HAZ of each base metal, and sets of three impact specimens shall be prepared from the unaffected area of each base metal. Base material and HAZ impact test data are not required for S-11 (HY-80/100 or HY-130 or HSLA-80/100 only) or S-1 MIL-S-22698 materials, except that such testing is required for MIL-S-22698, grades D, E, AH36, DH36, and EH36 for heat inputs greater than 109 kilojoules/inch; base metal and HAZ testing for S-53A are also not required when approved by NAVSEA. When more than one set of specimens for the weld metal is required, each set shall represent a different weld depth level with one set taken from the test assembly midthickness (1/4T for double bevel joints). When double beveled butt weld test assemblies are employed, weld metal impact specimens shall be removed from each side of the joint (i.e., at least two specimens from each side). Specimens shall be prepared as specified below:

Base metal and HAZ specimens shall be prepared in accordance with figure 7-24. 6/ Tensile tests shall be transverse weld tensile specimens (round or reduced section). For S-11 materials welded to themselves or to each other and S-51, S-52, S-53, and S-53A base materials welded to themselves or to each other, and which are 3/4 inch and over in thickness, tensile tests shall include two transverse weld tensiles and two all-weld metal tensiles; when double bevel butt weld test assemblies are employed, one all-weld metal tensile specimen shall be removed from each side. 7/ When side bends are required for a given material and the test thickness is less than ¾ inch, two root bends and two face bends may be tested in lieu of side bends. If the procedure is for full penetration joints welded from one side without backing rings or preplaced inserts, root bends with the root surface in the as welded condition (i.e., no machining, grinding, etc.) are required when the root is welded without the addition of filler metal or without internal inert gas purge. 8/ Macro testing shall be per 4-5.2.6. 9/ Use a 3T bend for S-11B base material. 10/ See 4-4.1.3.1. 11/ Liquid penetrant (PT) inspection required (see 4-4.2.1) prior to destructive testing. Chemical testing for composition (or dilution evaluation when permissible) shall be performed per figure 7-4. Three macro-etch specimens and three bend specimens are required for pipe or other cylindrical product welds. 12/ Hardness testing is required for hardfacing and shall be as specified in figure 7-6. Chemical testing shall be performed only when specified in the applicable fabrication document or drawing. 13/ To perform qualification for root layer deposition and for depositing previously qualified fill procedures on root layers, in accordance with 4-4.1.4, four macro-etch specimens shall be examined and shall meet the requirements of 4-5.2.6 in lieu of RT, tensile, and bend tests; VT and MT/PT per this table also apply. If the procedure is for full penetration joints welded from one side without backing rings or preplaced inserts, root bends with the root surface in the as-welded condition (i.e., no machining, grinding, etc.) are required (in addition to the macro-etch specimens) when the root is welded without the addition of filler metal or without internal inert gas purge. 14/ Dynamic tear testing as specified in ASTM E604 may be substituted for CVN testing when the material specification (base or filler) or fabrication document provides for dynamic tear testing. 15/ Only VT and PT examination of the weld surface and two macro-etch specimens in accordance with 4-5.2.6 shall be required where test assembly thickness is 0.058 inch or less. 16/ VT inspection of all test assemblies shall be performed prior to other nondestructive testing. NDT shall be per 4-5. 17/ For S-51, S-52, and S-53A materials, bend radius shall be determined in accordance with AWS B4.0 using minimum base metal elongation. For S-53 materials, the bend radius shall be 8T. 18/ See 4-4.8. 19/ Inspect 100 percent of weld when RT or UT inspection is specified, except as permitted by 4-5.1. 20/ UT inspection shall be performed on material 1 inch thick and greater in accordance with 4-5.
