Gouge or Notch Limitations. Roughness
exceeding these values and notches or gouges not more than 3/16 in [5 mm] deep on otherwise satisfactory surfaces shall be removed by machining or grinding.
Notches or gouges exceeding 3/16 in [5 mm] deep may
be repaired by grinding if the nominal cross-sectional
area is not reduced by more than 2%. Ground or
machined surfaces shall be faired to the original surface
with a slope not exceeding one in ten. Cut surfaces and
adjacent edges shall be left free of slag. In thermal cut
surfaces, occasional notches or gouges may, with approval of the Engineer, be repaired by welding
