LT, whichever is greater.
c. If the total cumulative length of discontinuities in any 300 mm 12
inches of weld length exceeds 75 mm 3 inches or 2 T, whichever is
greater, that weld length shall be rejected.
3.4.2
Full Penetration Tee Joints
Full Penetration Tee Joints (for Incomplete Root Penetration): Any
discontinuity with the reflection exceeding the established reject/repair
line of the applicable class shall be rejected. Any discontinuity with a
reflection exceeding 25 percent of the established reject/repair line, up
to and including the reject/repair line, shall be rejected if its length
exceeds 1/2 T in a direction transverse to the axis of the weld or LT
parallel to the axis for all classes. If the total cumulative length of
discontinuities in any 300 mm 12 inches of weld length exceeds the limits
of the applicable class, that weld length shall be rejected.
3.4.3
Partial and Full Penetration Tee Joints
Partial and Full Penetration Tee Joint Boundaries: The depth of weld
penetration and weld cross section width at the through member surface
shall be as indicated by applicable plans or drawings. Limits of
discontinuities shall be as specified in preceding paragraphs.
3.4.4
Tee Joint Discontinuities
Tee joint discontinuities extending into the through member shall be
rejected if [reflection exceeds the established reject/repair line.]
[reflection amplitude is in the range of minus 6 dB of the reject/repair
line and the discontinuity extends more than 1.6 mm 1/16 inch or more into
the through plate.] [the total cumulative length of discontinuities in any
300 mm 12 inches of weld length exceeds 100 mm 4 inches].
