RE: welder qualified
How corrosion-resistant do you want your finished P10H component to be?
I would do nothing less than qualify each of my welders with corrosion testing to ASTM A923.

RE: welder qualified
Both base metal P no and Filler Metal F no are essential variables for welder.
GTAW F no being 6 for both carbon steel and duplex consumables, you may use welder qualified on P1 to weld P10H
For SMAW F no is not same for carbon steel (F no. 4) and Duplex (F no. 5). In this case you may have to run his qualification tests.
