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.

 

Pipe	NPS:10-Thk:45mm-PIPE-API 5L GR.X65 PSL2 - SMLS -GA-E-61036	BW	3mm Inconel Cladded
Pipe	NPS:12-Thk:15.88mm-PIPE-API 5L GR.X65 PSL2 - SMLS -GA-E-61036	BW	3mm Inconel Cladded
