(OP)
we have a WPS P8-P8 , did all testing required (tensile, bends etc). question , based on QW 432.1 it is my understanding that we can test welders under this WPS using P1-P8 ,P8-P44 coupons , if the coupon test pass (RT) then the welder is qualified to weld any combination of these P1-p11,P34,P41 thru P49 . what say you folks.

There are separate essential variables applicable to the qualification of welders that must be adhered to. These have nothing to do with the essential variables for a WPS.
See QW350.
RE: wps questions
You are still required to have a WPS -- Procedure -- qualified to the appropriate Essential Variables. Those variables are much, much narrower.
