eddy current testing of EBweld joint

sir,
i have a specific case that an EB weld is made in a solenoid bobbin with weld thickness approx. 2.5 mm flush level (flushed root and crown). practically you can not distinguish weld and parent metal if you see visually. Radiography/UT is not practicable. material is steel AISI 446.

Now to qualify this weld ,Can we use EDDYcurrent testing? please give details of how to fabricate specimen for this type? Furnish details if any literature available on this type of issues.
thank you
gowrishankar
