Plate defects occur in a variety of forms including burn gouges from cutting, deformations due to handling, mill plate defects, direction of rolling, etc.  The QA/QC inspectors should refer to ASTM A6 and AWS D1.5 for acceptable tolerances, repair procedures, or rejection procedures.  Approval for repairs in accordance with ASTM A6 and/or AWS D1.5 is permitted with the application of an approved WPS.
