Broken eyelgalss frame -- need to repair? - how do i separate a soldered piece of copper

My glasses metal frame is broken in the nose (which the ship separates into two halves). The breach occurred when the nasal riight curve fits to the main screen, right next to the lens.

A soldier of the previous repair "closed" so the screw can not I take the lens, so that the weld is released. I did not try "" a little superglue, but it is not expected. However, there was a "brand" and must not have been a better choice. Is there an adhesive cement / epoxy I use to get in touch (maybe 1-2 mm of contact is Avaialable) on both sides of the metal structure of a relatively "good" for the repair? Not sure of the material, but it is lightweight and can be aluminum or light.

I wear contact lenses, so that they are protected andN'T wanrt to $ $ $ to spend for a new series because it is rarely used.

QAlso all recommnedqations how to link to improve the best forces would also be useful.

Thanks in advance
