Duwe6,
The interpretation below seems to state you can't create multiple WPS's from 1 PQR (or am I reading it completely wrong).
Your thoughts ?,

Subject:
Code Edition: Dl.1-90
Code Provision: Subsection 5.5
Qualification of Multiple Welding Processes
AWS Log: 1-9/9 1-1 0-03
Inquiry: (I) Can one or more welding processes be deleted from a qualified welding procedure in accordance with AWS D1.l, subsection 5.5, if each of the essential variables for each of the remaining processes is maintained?
(2) Based on a qualified welding procedure involving a GMAW root pass, SMAW backweld, and SAW fill and cap passes; [can this WPS] be separated into its component parts to qualify other WPSs, as shown in the Inquiry letter?
Response: (1) No.
(2) No, the acceptance or rejection of specific WPSs is beyond the authority of the D1 Committee.

I would imagine that you could build multiple WPS' from a single PQR as long as essential variables are not changed. Seems more of an acedemic exercise; as an example, if you had a SMAW PQR qualified for 3/8" to unlimited at 6G, you could make a WPS limited from 3/8" to 3/4" for fla and horizontal; another WPS 3/8" to unlimited, all positions, etc.
Not that you would want to....but could be applied to certain applications/personnel...

It's probably worth submitting an official interp on it. There has been discussion among committee members regarding the possibility of validating/upholding interp responses over new Code year editions, and this one may be a good example.
