Any luck with plastic 'welding'?

[Hutchew]

Any of you ever had any luck in having plastic welded? I came across a company that will modify the 93 fuel tank I have to make it work in my conversion. They said it works good, but was wondering if any of ya'll have ever seen or had it done, and if it did actually work ok. Funds are getting real tight, and I don't wanna waste the $$$$ for nothing... ... ..... TIA, again.

Firetrucks now use a plastic water tank. Durablility has been much better than the steel tanks. The fire department purchased a welding "torch" and supplies to fabricate plastic equipment boxes.



With a little instruction, it is not too difficult to get the hang of welding. At first I was trying to do it like oxy/acet and it did not work. Once I looked at the manual and had a little instruction, things went well.



I do not recall what particular plastic we are using but it is about 3/8" thick and white. The manual with the "torch" talks about the relative ease and practicality of different polymers.



If this guy does this regularily, I would not be hesitant to use a plastic tank. If he just got a setup and thinks it might be a good way to earn extra money, I would avoid it. I would ask for references.

Your local auto parts store should have some plastic tank repair kits on the shelf. I've used the metal fuel tank kits with good success, so I assume the plastic ones work too.



The kits consist of an epoxy with both parts in a single sealed bag, some coarse sand paper, several square inches of fiberglass fabric, a hard soap stick to seal the leak while you mix and apply the epoxy, and an acid brush to apply the epoxy.



I've never had to redo any of the metal tank jobs that I've repaired.
