As per AWS D.1.1 , a PQR qualified from Any group II to an unlisted steel is also qualifies/covers WPS for Any group I to an unlisted steel?
Note : Unlisted steel will be the same grade steel which was used for PQR qualification.

Hello there,
If a PQR qualified between base metals P1G2 - P1G3 with in impact testing requirement as per the ASME IX.

Thx.
