Spin-holes with a diameter less than or equal to 60 mm (2 3/8 in.) may be closed with a full-penetration weld using either a welded plug or weld metal. The thickness of the weld and plug shall be greater than or equal to the thickness of the head material adjacent to the spin-hole. The finished weld shall be examined by the magnetic particle or liquid penetrant method in accordance with Part 7. Full volumetric inspection of the weld in accordance with Part 7 shall be performed in addition to any examinations required by the material specification.
