Welcome to the Forum Remote.
I think you may be misunderstanding scope of D1.1 Clause 3 (Prequalification of WPS's).
The code does NOT
provide any actual prequalified procedures that can be used in production.
Clause 3 lists base metals, processes and joint configurations that have been proven historically to be consistently joined when the essential variables (also listed in tables in clause 3) are applied within the limits specified.
It's a pretty common mistake so don't feel bad.
So while you will not find production WPS's in D1.1, in clause 3 you will find the base metals, joint types, and essential variables that you can use to create your own prequalified WPS. If the process, base metals or variables do not fit into the scope of Clause 3, than you must qualify the procedure by testing via clause 4.
Here is a link that takes a few baby steps in explaining in more depth. Written with love by one of the posters here.http://spotidoc.com/doc/162407/what-are-welding-procedure-specifications%3F
