Dear Expert,

I am having 2 PQRs i.e.:
1. 2" Sch. 80 Pipe (thk.-5.54mm) - GTAW (70S-2)
2. 6" Sch. 160 Pipe (thk.-18.26mm) - SMAW (7018)

My question is: Can I combine these 2 PQRs for buiding up one more making new WPS for 8" Sch. 80 Pipe (thk.-12.70mm) using GTAW+SMAW (Root and hot with GTAW and filling and capping with SMAW)

Thanx in advance
