Dear All,

I have PQR of GTAW + SMAW process for P1G2 to P1G2 (SA516 GR.70 to SA516 GR.70)

PQR Plate thickness = 10 mm

GTAW welded = 4 mm

SMAW welded = 6 mm

WPS range qualified = 1.5 to 20 mm.

Now, My query is, can i use this WPS for WPQ by GTAW process only?

I want to qualify my welder on 1/2"NB X SCH 160 (4.78 THK) pipe with only GTAW process using this WPS.

Kindly Clarify Experts........

Regards,

Brijesh Maurya
