Hi, You can use the WPS but check for the thickness qualified for GTAW process in that WPS.If GTAW process in that WPS is qualified for equal or more than 6.55mm , then you can go ahead.(For WPS Diameter is not an essential variable only thing you should have a qualified welder for this basemetal,dia and thikness,filler metal etc.,)
Thanks & Regards,
