Dear Experts,

 

I need some clarification in document review. PQR qualified in FCAW process for 27 mm plate in 3G position. WPS is prepared for structural joint for 34 mm in all positions.What is the essential one?

 

1. In FCAW proces PQR , Electrode AWS no. E71-T-1C is used. But in WPS E71-T-1 is mentioned. Whether its ok?
2. PQR in FCAW qualifies 3G position of 27mm plates as per ASME SEc.IX and API-650. What is qualification of position in WPS for 3G whether its ALL POSITION or only 3G postion?
3. The WPS is to be used for structural activies. ie. as per AWS D1.1. But in WPS also mentioned reference code as ASME sec.IX and AWS D1.1.

Plz clarify.

 

Thanks

 

Arvinda.
