ASME IX F number issues....
ASME IX F number issues....
(OP)
Could anybody please clear this up for me. I have a PQR that was made with a 6010 (F3) root and a 7018 (F4) fill. The WPS was revised to show making the weld with only 7016 (F4). My stance is that this PQR does not support the production 7016 only weld.

In your specific case, a new WPS should be written using the original PQR that supports a F-No 3 weld root and F-No 4 fill in accordance with the weld production requirements.

Back to the WPS in question. stanweld is exactly correct. The F4 portion of the PQR can be used by itself to support a new WPS.
