Agree with rustbuster.

If the object operates at or above 800 deg F you should consider Inco A weld metal versus E/ER309L to avoid premature failure along the SA 387 Grade 2 side of the fusion zone.

If it's for an Oil, Gas or Chemical industry application, API RP 582 gives specific guidance and limitations.

We are doing this procedure for our mechanical contractor.
Currently we maybe using it under B31.1 in a high temp high pressure steam application.
Thanks
