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
