(OP)
Dear All,
With regard to GTAW WPS, if the WPS mentioned that the filler wire diameter is 2.4mm but the available filler wire size for GTAW is only 3.2mm. Does we require to provide new GTAW WPS?

What is the reference code for WPS qualification? If the qualification of welding procedure is based on ASME Section IX, you do not need to qualify a new WPS if the diameter of filler wire changes because it is a non-essential variable.

We are working under ASME Section IX.
Thank you for the prompt response.
Is your reference Table QW-256 (GTAW)?

The same holds true for the weld type (fillet versus groove weld) as well as joint type (Tee, Butt, Corner, etc.), and groove type (V, J, square, etc.), groove angles, single pass versus multiple. the list includes any nonessential variable. If the WPS only lists one weld type, one groove type, etc., that is what the welder is limited to.
