There is no difference. They are the same thing.
 
AWS prefers the use of CJP (Complete Joint Penetration) and PJP (Partial Joint Penetration).

F.P. (Full Penetration) and P.P. (Partial Penetration) is obsolete terms.

C.P. may be understood but it is incorrect.
 
A CJP weld develops the full capacity of the connected parts, where a PJP weld does not. How much strength the PJP weld develops is based on the effective throat. The effective throat of prequalified welds are given in the AWS table for that weld.
