For base metal are assigned in QW-420 - base metal grouping and table QW-422 + P-Number + Gr-Number. For filler metal are assigned in QW-430 and table QW-432, QW-442 + F-Number + A-Number. Just dance 2019 iso wii. Read more QW-403 Base metals qualification ASME IX. Grouping of base metal. P-Number are assigned to base metal for purpose of reducing the number of welding. F-Numbers to filler materials! The following F‐Number grouping of electrodes and welding rods in Table QW-432 is based essentially on their usability characteristics, which fundamentally determine the ability of welders to make satisfactory welds with a given filler metal.

I am not sure in what context you are speaking of completely.
In AWS D1.1 there is NO F-6 listed as an F number in Table 4.13 so it does not apply. Table 4.12 item 2 specifically says 'To an SMAW Electorde with an F-number higher....) indicating F number is only an consideration for SMAW
ASME handles F Numbers differently and for tyhe most part says the same thing but addresses more Fnumbers.
Regardless, F Number is NOT the only consideration. For any of the variables to work within their range, all other variables must be within the range of qualification. Keep the same F Number but change another variable (Position, Process, Thickness, Backing, Progressions, etc..) In you example below you refer to F6 which is NOT an SMAW F Number but then you refer to 7018. In that case the statement changes the process so another variable is changed.
If you are not intimately familar with 'The codes' I would strongly caution questioning anyone else in a production setting until you become more familar.
As far as D1.1 Clause 4 will address what you need to know regarding variables for performance qualification.
