How to remove a welded latch on a Wrought iron gate?

I am installing something in my backyard that will not work with my latches/strikers on my Wrought iron gates.

It's actually a cat fence that gets in the way of the latch/striker.

Is there a way to weld these off like you would with plumbing solder? Or is it basically cut and file? It would be painful if I had to go this (cut & file) route.
