Dear Hegde

 

Why not mix up ENiCrFe3  or ENiCrFe2  ?

 

With kind regards,

i)You can butter either by ENiCrFe3  or ENicrF2  individually but no mix up

ii) After buttering on P4 you require to carry PWHT of that buttered components

iii) later on further butt joint  with Inconel ,you need go for PWHT

 

Regards

Dea Sir,

 

I would like to qualify a new PQR for this application. Can I use ENiCrFe2 for buttering & ERNiCr-3 + ENiCrFe2/Fe3 for the buttwelding?.

 

Or I need to go for ER NiCrMo-3+E NiCrMo-3?.

 

Regards,

 

Ibrahim

You may use Inconel to Inconel PQR for butt weld, however for buttering you require a separate buttering PQR for buttering thickness less than 5mm or a groove weld PQR on P4 material welded with Inconel can be used when your buttering thickness exceeds 5mm. Weld overlay PQR can't be used for buttering.

Hi Members,

 

Kindly request your suggestion on the following matter.

 

We have to weld one 2" Nozzle (PNo.4) to Tube sheet with (PNo.4). Due to some practical dificulties we have to avoid PWHT of this joint. So we are planning to buttering both nozzle and tube sheet nozzle opening with Inconel. Then Butt weld the joint with Inconel.

 

We have one overlay procedure (SMAW) with Inconel on P4 material with PWHT and another butt welding procedure for Inconel to Inconel (GTW+SMAW) without PWHT.

 

Can I use these PQR together for this butt weld?.

 

Or I have to qualify a new buttering+buttwelding PQR with same condition?.

Thanks & Regards
Muhammed Ibrahim PK
