[MW:9855] electrode selection of WPS of SA 333 Gr 6 low temp piping, GTAW +SMAW

Dear Sirs,

Pl advise how can select the electrodes for SA 333 Gr 6 (P1 and G1) low temp pipe.

I want to prepare WPS / PQR and then also WPQ for our current project.

Have selected the thickness around 5.55 mm (2 “S 80 pipe) for preparing WPS.

 

We followed the process of root run by GTAW and then by SMAW.

 

Regards,

Abhay
