(a)
Welds and surruounding 1/32 inch of material shall exhibit a bright. shiny. silvery luster. Other conditions are unacceptable and shall be dispositioned as follows: Less of luster or colors other than straw or very light blue (e.g.. blue, yellow, gray etc.,I) shall require complete removal of the affected weld bead along with 1/16-inch minimum of surrounding material. Straw or very light blue color on surfaces to be welded over shall be removed prior to further welding. Very light blue on accessible final weld surfaces shall be removed. Straw color does not require rentoval from final weld surfaces. For areas beyond 1/32 inch frola the weld toes. All discoloration on surfaces to be welded over is unacceptable and shall be removed prior to further welding. Colors except for straw on other surfaces shall be removed. Removal may occur after completion of welding.
(b)
10.4.1.1 General. VT inspection shall be performed using a written procedure and qualified personnel in addition to the requirements of MIL-STD-271. VT inspection qualification and training shall be documented in a written procedure. VT inspection shall be accomplished without the use of magnifying glasses or other visual aids except for corrective aids to restore normal vision. 10.4.1.2 Welds. YT inspection of welds shall be performed after slag removal and with the weld in the final surface condition. For welds in S-51. S-52, and S-53 materials VT inspection for color (contamination) shall be in the as-welded condition before wire brushing or any other cleaning. After correction of unacceptable color condition. a final visual inspection for color shall be performed. 10.4.1.3 Base material. The surface to be inspected shall be in a clean condition. Surfaces which have been cleaned and painted with one coat of primer are considered suitable for inspection. 10.4.2 MT and PT inspection Acceptance of welds and the adjacent base metal subjected to MT or PT inspection shall be in accordance with the standard and class requirements specified in table XI. Acceptance criteria for cladding or weld overlay shall be in accordance with the class specified for the weld application: however, where weld cladding is used to provide corrosion resistance for gasket seats or similar applications. the following acceptance criteria apply: O-ring or gasket seating surfaces plug 1/8 inch to either side of the designed gasket location or line of contact - - class 1. Other cladding normally subjected to liquid pressure - - class 2. Other cl adding normally dry (for exarple. on the low pressure side of the gasket) - - class 3. 1. 2. 3.
10.4.2.1 Adjacent casting base material. PT indications in casting base material adjacent to fabrication welds may be evaluated as follows:
