does anyone here know anything about the sonic welding process?

curious if you can re-weld a previous welded spot?

is the cloudy spot/corner from the case being cracked or is that simply some adhesive that has clouded up.

they used to just use krazy glue and it was extremely easy to spot...

if it's the adhesive, then they've gotten much better at concealing that part of it....

edit: imagining a mental picture of all these guys down in mehico setting up test runs w. all sorts of glue imported from all over the place
Here's some info.
Slabs are most likely polycarbonate (Lexan)

Rewelding in a different fashion or even the same might be possible, but would be a bit of a challenge.

Assuming a take of 150K a month or better, there are very few technological hurdles you could put in the way that would be all that hard to defeat.
Even the treasury believes that counterfeit notes are available very soon after the release of the new designs.
