Any change in Groove type as below is considered essential variable.

 

1. Single Bevel

2. Double bevel

3.Single Vee

etc...

 

If there is a change in any of the Groove type, a new PQR shall be Qualified.

 

Exception : If your PQR is Qualified using any of the Groove types described in 3.12 or 3.13 using Complete Joint Penetration (CJP) then all the Groove types described in 3.12 or 3.13 is considered Qualified and the PQR can be used without requalification.

Dear All

Can you please explain the below clause in AWS D1.1 regarding groove type:

I have a PQR qualified in Single V. Whether the WPS supporting this PQR can qualify Single Bevel?

Thanks and Regards

Harikrishnan
