Note that
For base metal T ia applicable and for weld deposit t is applicable.
So ur base metal qualified is 2T for all processes but 4 deposit is only 2t.
So
GTAW 10 MM
SMAW 40 MM
FCAW 50 MM
DEAR EXPERTS CORRECT ME IF I M WRONG

         PQR WELDING PROCESS : GTAW +SMAW+FCAW
         WELD DEPOSITION THK  a) GTAW :  5 mm
                                                 b) SMAW : 20 mm
                                                 c)  FCAW : 25 mm
       
 As per  QW-451.1 note 3  ,  the SMAW, SAW, GMAW, PAW, and GTAW welding processes only; otherwise per Note (1) or 2 T, or 2t, whichever is applicable.

Can i use above clause for FCAW
