Hi Mike,
I think what they are asking for is a "prequalified" full penetration weld. This is a weld that can be completed without qualifying a procedure first to prove that it will work. There are examples of these different "prequalified" joint designations in AWS D1.1 Structural Steel Welding code(AWS has already proven these to work, if followed). Section 3 (page 57) of this code specifies what criteria you must meet for the welded joint be considered a "prequalifed" status. If you have a copy of D1.1 :2004, the prequalified CJP details start on page 88 of Figure 3.4.
This should get you started in the right direction. If you need more assistance, post again with more info about the joint type, position, welding process to be used and etc.
