[MW:27610] SA 350 LF2 normalized & Temper WPS

Dear Expert

I have sa350 lf2 flange in normalized &temper condition, tempering at 620 deg cel
This needs to be welded with sa516 gr 70 normalized condition
For same i have wps with metal group p1g2 to p1g2 (normalized),

Kindly advice

1) is there a requirement of new wps as one of material is in normalize + temp condition or existing wps for normalized condition is applicable

2) Pwht temp in existing wps is at 620 deg cel
Will this needs to change as tempering of sa350 lf 2 is at same temp

3) if new wps is req then for PQR can i use normalized sa 516 gr 70 plate tempering to same at 620deg cel ( to simulate SA 350LF2 ) then welding follwed by pwht at 620 deg cel
