If the qualification is based upon ASME Sec IX, as per QW 402.4 elimination of any type of Backing constitute an essential variable. Addition does not not considered as Essential variable for performance Qualification. Welder is qualified in your case.
If the qualification based upon API 1104, This constitutes an essential variable (Joint design 5.2.2(g). Addition or deletion of backing needs a new qualification. The welder is not qualified. But this interpretation is debatable.
