Full penetration groove weld?
"What we have is failure to communicate."
The acronyms used by AWS is CJP for a complete joint penetration weld. Only groove welds can have complete joint penetration. And PJP is the acronym for a partial joint penetration weld. Again, only groove welds have "joint penetration."
Fillet welds are required to have fusion to the root, but not necessarily beyond. If the designer wishes to penetrate the joint, he should be specifying a groove weld, either CJP or PJP.
Going back to the unofficial definitions I use: Fillet welds go on the joint, groove welds go into the joint. I use these definitions whenever there is a disagreement whether the weld is a FW or a GW. Thngs gt dcy whn txting bcms a wy of lfe.
