Dear Kisan
As per QW404.22, addition or deletion of consumable inserts is non-essential variable for Welding Procedure Qualifications. You can use the same WPS.
However for Welding Performance Qualification, as per table Qw-356, addition or deletion of consumable inserts is "essential" variable for manual and semiautomatic GTAW. Thus your welder needs to be requalified with the consumable inserts.

Hi Kisan,
As per ASME SEC IX QW 404.22 it is non essential
variable. So you can use as it with insert.
Please read below given Clause.
If any doubt is in your mind feel free to call or mail
me.
QW-404.22 The omission
or addition of consumable
inserts. Qualification in a
single-welded butt joint, with or
without consumable inserts, qualifies
for fillet welds and
single-welded butt joints with backing
or double-welded
butt joints. Consumable inserts that
conform to SFA-5.30,
except that the chemical analysis of
the insert conforms to
an analysis for any bare wire given in
any SFA specification
or AWS Classification, shall be
considered as having the
same F-Number as that bare wire as given in table
QW-432.
Thanks
& have a nice day
