13.2.8.3 Radiography of completed repair. Repair welds in casting areas originally requiring radiography shall be radiographed except in the following case: Radiography is not required for repair welds of defects not detected by radiography or pressure test If they conform to the criteria of 13.2. 2 for minor repairs and are satisfactorily PT or MT inspected as applicable. 13.2.8.4 For repair welds in castings that require radiography which are 3/8 inch and greater in thickness and are made with MIL-120s or MIL-12018 filler metals. also perfom the MT inspection required by 10.3.12. 13.2.9 Acceptance standards for repair weld. Acceptance criteria for repair welds shall be as follows:
Inspection
Acceptance
RT MT PT Method
( see note 1) MIL-STD-2035 (see note 2) MIL-STD-2025 (see note 2) Standard
Notes:
Repair of casting radiographic indications is required only to the extent of bringing such indications wtthin the applicable castlng acceptance standard. When radiographs are made after repair excavations, and prior to weld repair to determine the extent of any remining discontinuities, the acceptance standard for the design thickness of the casting in the excavated area shall apply. UT inspection employed in accordance with an approved procedure may be used for such thickness determination. For post weld repair radiography. discontinuities occurring in the weld shall be judged for acceptance to the applicable reference radiograph for casting defects. If the combination of weld defects and casting defects does not exceed the discontinuities allowed in the applicable referenced radiograph for castings. the area shall be accepted. Cracks. lack of fusion. and incomplete penetratiopn in the area of weld repair shall be rejected. Slag and porosity shall be judged as sand inclusions and gas. respectively. 1.
