You cannot really tell on the pic provided and further, it doesn't look "too" much like a vert down weld. Typically a vert down weld will wet out at the foot of the welds but be too cold for penetration and thus is where the problem(s) start.
Most V down welds will have a more pronounced inverted "U" appearance. If you look closely, you can see the the very edge a cold spot where the weld is not penetrating.
By controlling the heat and the weave, you can get a much better V Down weld with MIG
As to the question of how you can tell "This" pic was V Down, you can't for sure.--Grant
