[MW:25195] PQR Qualification.

All,

Please advice me in the following.
ASME IX :2013
Weld coupon base material P8 (ASTM A240 TP 316) to P1 (S333 Gr. 6)
FCAW: Filler metal Bohler CN 23/12 Mo PW-FD (E309LMoT1-4)

Does this PQR qualify a weld joint P8 (ASTM A240 TP 304) to P8 (ASTM A240 TP 304)
by changing filler metal into E308LT1-1 for both F No. 6 and A No. 8

Follow Table QW 255 Ø P-number qualified article 403.11 -> article 424.1 I should say no, but am I right ????


Diameter and thickness are in range.

Thank you.
