Done many of these. Worst thing about that slobber job is that is is unknown and unknowable strength. Probably needn't be completely removed but can be ground out and rewelded one side at a time. Best if done uphill with 7018 or similar.
What I see moreover, is that both hinges are turned the same direction, allowing the gate to be lifted off the hinges. If only one was reversed though it would put all the thrust on one hinge.
One could be removed and reverse the weldment to the other post allowing a tab to be welded above the hinge.
Or, remove both, put the zerk half on the post side and a tab above one or the other to prevent lifting the gate.
