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.
