--You should use E 8018 B2 or 8018B3L as SMAW consumables. SAW wire flux combination matching SMAW chemistry is also to be considered. If the hardness requirement is in place, then 8018 B3L would be advisable.
On Cr-Mo steels normalizing may sacrifice the Charpy impact , hence consumable with extra Mo(B3Lgrades) may be of help.

Subject: [MW:33147] SA 387 GR 11 CL2 and SA 387 GR 22 CL2
Experts
The dished end is to be fabricated with one number Chordal seam for MOC of
1) SA 387 GR 11 CL2
2)SA 387 GR 22 CL2
One chordal seam in dished end is coming due to plate size( width) limitation and the diameter required of dished end. So butt joint welding is to be done followed by NDT .
Hot forming is planned . After forming is completed, separate Normalizing and tempering Heat treatment is required as per Client specification.
PQR is to be established as per ASME SEC IX .
Pl. suggest suitable consumable and maintain strength
Pl. share experience if any
