NDT method to find out corrosion beneath RF Pad

Is there any NDT method to detect corrosion in shell beneath RF Pad on 2"Nozzle welded in 42" dia pipeline. RF pad thickness is 22 mm and nozzle thickness is 12.0 mm.We found leaks through RF Pad weep hole while in service and we suspect corrosion/severe thinning/crack around nozzle welded to the shell.
