The vertical up position typically has the highest heat input which has the greatest effect on impact properties. Therefore, a PQR qualified in the vertical up will satisfy for the other positions.

Members,
In AWS D1.1, table 4.6 point 6 states that: A 3G vertical up test
qualifies for all positons. If our PQR testing includes CVN
requirement, can we go for only 3G vertical test coupon qualifying all
positons?
Please clarify.
Regards
Avinash
