To begin with, I'm not too sure of what the item is that is welded to that large column. At the bottom of the item is obviously an electrical cable stuffing tube. Below that appears to be a cable support made out of 1" X 1/8" steel.
There are too many layers of paint to identify what the part is. There appears to be a lever on the right to open up a junction box (I think). To the left (through the deteriorated weld) you can see an opening into the column.
As for the weld, again there's too much paint to positively identify what went wrong. But there is enough bumpiness to strongly indicate the "welder" used straight polarity to just pour on loads of welding rod to make the item stick to the column. In straight polarity, the majority of the heat of the arc is in the welding rod and just plumps in molten metal without actually fusing the base metals together.
There is obviously no oscillation curls that would be evident of reverse polarity. In reverse polarity of heat from the arc is in the base metal to fuse it to itself with the weld only as a filler bead.
But since there is no obvious use for this item with an empty stuffing tube, just cut it off and weld a curved doubler patch over it (grind off that cruddy weld first though).
