Re: [MW:6467] P42 (Monel) to P1 (SA516 G.70) Welding

What is the type of joint? Shell to nozzle with groove and fillet reinforcement? Nozzle thickness?

Normally, welding of P42 and P1 is made without any PWHT operation.

Just perform the weld with the wires / electrodes you mentioned and get the procedure qualified. No need to butter the P1 side otherwise, you may need to consider PWHT after buttering.

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
