Dear Efriends,
Could you tell me which WPS's based on thickness,joint type,process type and...are prequalified?
I know there are details of them in AWS D1.1 but I want to have answer of my question exactly in some sentences.
Kind Wishes,
Nima

Hi Nima,
Any of the joints shown in Section 3 are prequalified, as long as you meet all of the essential variables listed in the table. You must write your own WPS and follow the joint details and essential variables to remain prequalified. Any deviance from the essential variables will require a qualification per Section 4 of your WPS by a PQR.

Sorry to say Nima, nobody is going to hand that information to you on a silver platter.  The information, as mentioned by John Wright is in the Code book... if you intend to use it I strongly suggest you read it.
