Flange Edge repair after Hydrotest - ASME Viii - Div 1

You can make minor weld repairs to the edge of flange without hydrotest (obviously, depending also on material restrictions), provided all the rest of flange geometry is intact, with no deformation beyond allowable tolerances. However, why are you wasting time and money with minor repairs to the edge of the flange? Aesthetics? Anything more than that could be a significant alteration to the pressure bearing component and that comes under vessel repair codes and standards.

Not enough information to answer the post. Is this flange on a completed Section VIII, Div 1 pressure vessel (completed meaning hydrotested, stamped, National Board registered). If so, weld repair would be under an in-service repair code and hydrotesting is not required after weld repair. NDT would suffice of the weld repair region.
