Description of Discontinuity Repair Required
Any discontinuity 1 in. [25 mm] in length or less None, need not be explored
Any discontinuity over 1 in. [25 mm] in length and 1/8 in. [3 mm] maximum depth None, but the depth should be exploreda
Any discontinuity over 1 in. [25 mm] in length with depth over 1/8 in. [3 mm] but
not greater than 1/4 in. [6 mm[
Remove, need not weld
Any discontinuity over 1 in. [25 mm] in length with depth over 1/4 in. [6 mm] but
not greater than 1 in. [25 mm]
Completely remove and weld
Any discontinuity over 1 in. [25 mm] in length with depth greater than 1 in. [25 mm] See 5.15.1.1
