Welding acrylic sheets?

Call "Jack" at Ultimate aquatics. He is a friend of mine who makes custom acrylic fishtanks for a living. He will be able to help- He uses a chemical bond that melts or chemically alters the plastic to an almost bullet-proof seam. I mean I have personally seen 1000 gal salt water fishtanks made from this stuff with no issues.

If he can't answer it, there is no answer.

In addition to RDF's friend, these people probably know more about joining acrylic than most:

I think from memory Chloroform is the solvent and will wick perfectly into well fitting polished joints I have never tried it on sheets bigger than a couple of ft. length. Charlie+

Actually what you want is lab grade Ethylene Dichloride. I built many an acrylic box with the stuff. We used hypodermic needles to deliver it right into the seam.

I made some replacement box lenses for bollards with that stuff. Very easy with the syringe and pretty strong, too.

Is "lab grade Ethylene Dichloride" food grade stuff (FDA Approved) ? Or is it toxic? Thanks.

It evaporates almost instantly. There is nothing left to poison anybody.

MSDS, see Section 3: Hazard Identification

I've used it a lot, but it is definately dangerous for both fire and health. The first thing is to use it in really well ventilated rooms. The second make sure there no sources of ignition anywhere near it. That high evaporation rate doesn't make it go away, just easier to get into your lungs, and closer to things that will ignite it.

In small quantities and with precautions, it can't be beat.
