Gents,
We have to weld a monel Nozzle SB165 (UNS N04400) (P No.42) to SA516G.70 (PNo.1) 45 mm thk
The vessel is required PWHT.
I need to qualify a PQR for this welding with ERNiCu+ENiCu-7.
Is it required to do PWHT of this joint (P42 to P1)?.
If PWHT is required what is the way of welding of this joint?
If PWHT is not required what is the procedure to weld it?
Is it required to butter the CS with monel before butt welding?
Is any post heting is required for this joint?
Thanks & Regards
Muhammed Ibrahim PK
