Full Penetration Weld Explained: What Is It?
A full penetration weld, also known as complete joint penetration ("CJP"), involves a special kind of groove that allows filler material to fill the entire joint gap. That is, the weld penetrates from the toe (top) to the root (bottom) of the joint. In contrast, a partial joint penetration ("PJP"), the second type of groove weld, does ...
