[MW:10314] Change of filler metal

Dear All,

 

As per ASME IX,Table QW 253, F and A number are essential variables and filler metal classification is supplementary essential variable. In one of the case, as per WPS, required filler material is E-7018 (SFA 5.1),but by mistake               E-7018-A1 (SFA)5.5 is used for welding.My question is

Is welding acceptable under same WPS or new WPS/PQR will be required. (without impact test requirement).

Is welding acceptable under same WPS or new WPS/PQR will be required. (with impact test requirement)
