Hi,

Two plates meeting at 90 degrees and welded together. It could be said a simple fillet welding, but what confuses me is those chamfers(or grooves) on the edges.
As far as I know, if there is a groove, it's called either PJP or CJP weld. What should those edges be defined as?
 
Those are just called bevels.

If the bevel preparation and the desired weld is as you have depicted above, then the welding symbol needs to be corrected. The welding symbol should define where the bevels are to be, as well as the depth of the bevels and the size of the fillet welds.
 
It is allowable to weld a groove with a reinforcing fillet over it in T and corner joints like this. The symbol is wrong - It should show the bevel symbol as a PJP weld would, and then the fillet moves away from the reference line and looks kind of like a flag on bottom of the weld symbol. Judging by the proportions, this would be a PJP weld.

PJPs with a fillet on top are a way to get extra effective throat out of the weld if you can't just put a bigger fillet on it for some reason (clearance, visual, etc.)
