correct, you need a new PQR

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.
