Dear Ganesh
what grade?, what type of failures (in NDE or in service?), any root cause analysis done.
Knowing the root cause and extent of damage is very important before attending repairs.
if you are considering these are as closure joints, then only Volumetric examination is permitted, otherwise check feasibility for in service testing
