Hi everybody,
See note 31, Table 4.5 in AWS D1.1 "A change in groove type (e.g., single-V to double-V), except qualification of any CJP groove weld qualifies for any groove detail conforming with the requirements of 3.12 or 3.13"
It mean that, We cannot write WPS for Double V if we had PQR single V.
- PQR qualify Single Bevel-WPS only write Single Bevel
- PQR qualify Double bevel-WPS only write double bevel
- PQR qualify Single U- WPS only write Single U
...............etc...........................
However, some project, my client have been approved WPS single V which write PQR single bevel. Pls help me clear this issue. Thanks so much
