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.
