If you have the leak fixed I wouldn't even grind on a repair in that location as it won't make a hill of beans difference in the engines performance, and dinking with it may produce another leak.
I agree 10000000% percent. Don't touch it. It won't know that little glob of weld is even there. Just let it be, and don't tell the fence leaning gurus what you did, because damn sure if you did they'd tell you you left 5 tenths in the table and totally screwed up the porting.
