Hi experts,

 

CLAD MATERIALS -WELDING

 

We have the following Clad Pipe and we are preparing WPS /PQR to weld this SPOOL.

As I know we need to use ERNiCrMo3 / 7018-1 Combination (if GTAW+SMAW) to Complete weld.

But if anyone is having experience with this, please advise whether we will go with

 

GTAW - ER NiCrMo3 ( Root & Hot )

 

SMAW – E7018-1 (Balance Filling /Capping).

 

Please Explain any troubles may have happened regarding dilution or not.

 

Need Aramco and International code reference? If any one has a sample WPS/PQR Please share with us.

 

Any corrosion test or NDT

 

Waiting for your scientific and specific reply.

 

Thanks in Advance.
