WPQR certified to D1.5 reciprocate to D1.1

To all,

I am currently reviewing documentation at a fabrication shop in which the Welders ( WPQR's) are qualified to D1.5 via PQR -WPS to A709 Gr 50 Material 1" thick to specfied positions 1G, 2G Etc. The shop also has written Prequalified WPS's for AWS D1.1. But does not have supporting WPQR's to D1.1. Does D1.5 certification of the Welders reciprocate as far as Joint design, Position, Material Catagory Type / wire with AWS D1.1 or will I have to have the Welders qualified additionally to the Pre- Qualified AWS D1.1 WPS's before they can conduct welding IAW D1.1

Thanks for you feedback

Tom

had the exact same problem EOR wrote a letter accepting welders qualifications.

i have seen some smart shops qualify D1.1 and D1.5 if they write the wps correctly.

Hold on.

If a D1.1 WPS is pre-qualified, and D1.5 WPS needs to be qualified (for say FCAW) as long as that's stated, and the welders are certifed and documented that way, why would you need to go back and re qualify a D1.1 already PRE qualifed WPS?

Maybe I'm missing something here.

When I test and certify my welders, I make sure they don't grind on the test coupon, this way they are certifed to both D1.1 and D1.5 in one test.
