Dear Elumalai,
On the top of Nickel based electrodes, E 7018-1 will not get bonding. Tensile value of X - 65 pipe is greater than E7018-1. So you have to go for complete weld with E Ni Cr Mo3.
Thanks and Best Regards,
K.Rajagopal

Hi experts,
We have the following Clad Pipe and we are preparing WPS /PQR to weld this SPOOL. As I know we need to use ERNiCrMo3 / E NiCrMo 3 ( if GTAW+SMAW) to Complete weld. But if any one is having experience with this, please advice whether we will go with
GTAW - ER NiCrMo3 ( First four Passes- R/H/F1/F2)
SMAW – E7018-1 ( Balance Filling /Capping).
We have Pitting corrosion test as per ASTM G48 at 50 degree.
