COMPLETE JOINT PENETRATION AND PARTIAL JOINT PENETRATION GROOVE WELDS 

The Complete Joint Penetration (CJP) groove weld is a groove weld that extends completely through the thickness of components joined. The primary purpose for the use of the CJP groove welds is to transmit the full load-carrying capacity of the structural components they join. Most CJP welds require a specific edge preparation. The CJP welds should be used when deemed necessary, but should be kept to a minimum. Fillet welds are the preferred method of joining components owing to their overall economy, ease of fabrication and adaptability.

The Partial Joint Penetration (PJP) groove weld is a groove weld that does not extend completely through the thickness of components joined.
