Awesome vid! Ive welded a bunch of Teflon sheets, pvc and cpvc pipe using Seelye hot air torch equipment. Benefits are that you don’t have to remove a section for a repair like you would with glue. I’ve repair welded 90 degree elbows that were cracked in 8” cpvc (multiple passes to equal thickness of the base piping. Plastic welding in some cases is stronger than glue and will retain the plastic properties where the glue may deteriorate due to chemical exposure.
We have a 10" sch 80 PVC tee That is hub to hub w/ no space for repairs on process a header for an injection molding client. Would you recommend the Seelye Air torch and can you weld over Oatey sch 80 PVC gray glue w/ this process
@@jpump9236 I personally can recommend it, but the welding over a glued joint, although I know the plastic will bond fine I’d be careful about letting the glue melt and bubble up and cause lack of fusion in the joint. You’d do as many passes as possible so it would equal the thickness of the pvc. Don’t overheat the plastic. Just heat enough that it melts and bonds. Use filler that’s same as base material. If it’s turning brown or charring then back off. There’s an ideal temp where it melts together or overheats and becomes brittle. There’s different tips you can use to get around tight spots. Works best at lower air pressure. Good luck!
@@odinslockllc Thank you so much!! I believe I will have the guys go up today and take an end grinder to remove the glue or as much as possible. Hopefully this helps mitigate the issues we face w/ porosity. Our machine is supposed to arrive tomorrow and we did get the one w/ self contained compressor. I wasnt sure on how much rod would be required so I ordered 5lbs of 5/32" and same on 1/8". Hopefully this provides enough for guys to get acclimated to machine, rate of travel, etc. Is it possible to create welds that are uniform like walking a Tig cup or just a weave of a 7018 Thank you so much for taking your time to respond!! Had it not been for the comment and you referencing the machine I would still be searching!!
@@jpump9236 I wouldn’t try any weaving. Smooth welds is always better. Stagger your starts and stops so they’re not on the same spot. I’ve seen leaks because people didn’t stagger them. Btw, we’ve had 8” schedule 80 pvc elbows break/ split open from using a piping jetters and we’ve welded them with our seelye plastic welder and they lasted just fine. Where ever possible on repairs like that grind a V groove for penetration. On a joint though, just lay it in there like they show in this vid above. Seelye inc has YT vids that show how to do it as well. This vid above is excellent because it shows it turning brown at times. That’s the threshold for how hot you want it. When it starts turning brown your getting too hot and need to spread the heat or travel faster. Check out www seelyeinc-orl com. Good luck!
Hello sir, I was wondering where you can buy one of those gun style thermoplastic welders instead of the straight one. And also does your machine just run on air or can you use an inert gas as well?? Thank you
at my country indonesia we can buy online here, this tools use electric power source so it only can use on air ya... at the market we found only electrical power to run that tool. thank u
Abachriel Puastologawa so what’s the rod material you’re using? PVC? ABS? Can you explain what the material is that you’re using to fuse the plastics together?
CK_32 I use PVC rod, I buy it at local market here in Jakarta and the welding machine is the hot blower special for pvc welding you can found at local welding store I think..
Material pipa dan batang las harus sama panas supaya nempel kuat, kalau hanya pipa yg panas tidak nempel. Sama halnya dengan solder pipa tembaga atau yg lainnya
