Dear Vijay
you are not given clear details about the location and type of repaire.
generally the following steps to be follow---
first thing is to ensure the type and depthe of defect by ndt methods as per site conditions.
if a repaire is crack
drill at the both ends of crack to prevent further propgation of crack during grinding.
remove the defect by grinding only(gas cutting is not allowed).
after grinding ensure compleat removal of crack/slag etc by applying ndt methods
weld the cavity and apply final ndt (ut or rt)
apply highly penetrating oil to ensure there is no leakage.
if necessary check the hardness value
i think this information may help you.
with regards
