How strong is solvent welded plastic?
I've just made a headlight cover out of perspex which I "glued" together using solvent welding fluid. I'm fairly pleased with
the result but I don't want to try breaking it to see how strong it is. How strong is solvent welding usually?

Could you provide the brand of this fluid?
Are we talking about chemical or mechanical bonding? The first is better of course!

If the solvent and perspex are compatible, and the solvent has actually desolve the perspex to 'weld' it together, you'll probably
find the perspex will break before the joint, it is very strong.

after a fair bit of use,

Basically the same as welding, need to ensure plenty of contact area and compatible materials

The fluid is called poly-weld. It says acrylic on the bottle and to be fair, it seems to have done the trick.

Well, Perspex is acrylic, so that would seem to be ideal

I doubt if the radiator will be acrylic, you need something like JBweld or Araldite industrial. There's also Devcon which should do it too, try
googling round.

I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.
