Great video for learning how to weld plastics.
I have just started a job using this equipment going to try some of your steps to improve my welding thankyou
What tip would be better for welding a T weld? I'm planning on welding two HDPE barrels together perpendicular to each other notching an end of one to be welded to the side of the other. I was thinking the triangle one since most of the joint would be 90 degrees but not sure. Thanks for your help!
Like older motorhome/ camper parts too! Thx for the tips
An excellent presentation. Thx for sharing.
We use PVC type 2 how well would this hold? We are having separation issues with gluing now.
Super Video.Danke!
Great information thanks for sharing! New supporter here and I’m new to plastic welding!
A video on welding inside small containers would be useful. Product videos from companies always show using their product in easy situations.
Hi Bob, thanks for your comment. This video is to assist in teaching the process. Its not an application video. If you have a specific requirement, please email me full details and I will address it for you . you may email us at info@techspanonline.com . I hope this helps. Seasons greetings to you buddy ..
Thanks for the video!
Actually thus technic is great for motorcycle plastic. when you consider the cost of a single fairing or dude panel can cost $900.00 it's very cost affective. I tried this once and the weld bonding is 3 times higher then normal factory bonds. great stuff if you need to restore panels that no longer can be bought or found.
I just bought an American version of this welder that is obviously cheaper looking. This is a great video and previous research has told me to keep the heating element from burning out, you should keep the welder on After welding with the heat turned to Zero to cool the element before unplugging. My welder did not come with the automatic feed nozzle and was wondering where I can purchase this. Thanks for the great video, RH DSD

Absolutely loved this video! 😎👍
Thanks Danny Herrera .. we have tried to help show just how easy it is to achieve. :-)
Hi there, If the plastic you are trying to weld is a 'thermoplastic' then it should be possible to weld it. You can do a small test to establish whether it is a thermoplastic or a thermoset - using a sharp blade, cut a slither of the material off the parent. If it curls up, then its a thermoplastic. If it remains very rigid and straight, then it is a thermoset. A thermoset materail is not weldable. Hope this helps.
When you ask your wedding DJ friend to edit your instructional welding video
Quick question, When welding an internal corner on two upvc sheets, vertically, do you need to have a gap between that materials to give the weld rod somewhere to melt into?
It depends on the application. If you are after structural strength, perhaps this is best. A "v" groove usually does the trick.. If you are welding into a 90 deg, then no. But you would need to '"tack" the materials.. Have a look here for more detailed info - www.plasticweldingtools.com.au/how-to-weld-plastics/
Hello, greetings from South Carolina USA. I have a question specifically pertaining a splicing operation of Nylon 6 extruded monofilament (0.055-0.170 diameter). How would a hot-air process like this compare in tensile strength to an ultrasonic process? Thanks for your time, Bob
Hi Bob, weld strength can be very strong by hot air welding. Ultrasonic welding is an extremely fast process and usually used in the packaging industry. Hope that answers your query. Regards, TECHSPAN
great video ... informative and helpful.. you make it easy to learn . thanks for sharing..

Thanks. Our equipment complies with worldwide welding standards as set by the DVS joining association in Switzerland. You will find that two this requires two important factors - Heat & Pressure. It is very important to provide pressure on the welding rod if you wish to achieve structural welding.
I want to buy one, do these create strong reliable welds though ? For example is the weld as strong as the material its bonding ? In this case I will be welding HDPE Thanks
That and a laser cutter and you could make so much cool stuff!! How strong is the weld could you show some testing....unless you already did i forwarded a bit.
We only provide plastic welding equipment approved to DVS standards. What this means is that the welding procedures, techniques and associated equipment will provide very high strength structural welds. Hence why we are very big on ensuring the techniques for welding plastics are followed.

pretty snappy music! Makes me want to dance!
Interesting how we have different takes on the music...for me, it wasn't at all liked. I am normally an emotionally stable guy....but for some reason, it caused anxiety.
This video is a trip. I feel like I should be watching it on a hit of bomb. Seriously though, I just replaced a plastic gas tank on a chevy truck, because a tweaker cut a slice in it with a utility knife to steal the gas, and I was thinking about what it would take to weld the slice. Welding plastic gas tanks in the future may be more common then you could imagine. Inflation, an high gas prices are coming. If I saw it once, it will happen again, and again. Just like converter thefts. I would like to see if it can be done. If it can, I would probably buy this product.
Dude you’re so right this video is a fucking trip
Is this equipment/technique suitable for repairing a motorcycle fairing? I purchased a bike with some fairing damage with the view to repairing it.
great video
Hi bunkkasponge, you are correct. As with all forms of welding, any oils, greases, atmospheric soils, paints etc, can effect the welding... so it is important to ensure good clean surfaces for successful, strong structural welding.
Cracking Job, looks very professional.. were can you buy the sheets of material you used would like to make a small planter this way? Thank you
Hi kev b , Depends on where you are located. We source this kind of thing in Australia & or New Zealand through a supply known as Mulford Plastics. There are others, google 'plastic sheet suppliers' and you should turn a few up. All the best.
Thank you for the info, and fast reply
Cheers... now I know I have other work opportunties... :-)

Thanks.. I have been amazed and how many have made some positive comments. And others not so positive.. funny ole world .. Enjoy your day. 🙂
Nice product and instructional. I would have liked to see these joints cross cut to show the root and penetration achieved.
Hi wildcard, thanks... we hope to produce more helpful videos in the near future. I will see if we can include such a cross section cut as it is quite interesting to see the penetration.
very helpful
can you use a hair dryer?
if you are welding 90 degree angles, the contact edge of the sheets don't weld together do they? just on the exterior?
Thanks stonedeagle99, you are correct.. Use of a soldering iron will NOT effect a molecular weld as achievable with the correct equipment for the task..
GOOD VERY IMPORATNCE O WORK FOR THE HIMALAYAAN REGION, ,, A BIOLOGIST, ,,
I feel like I just joined the Plastic Cult.
No. You need accurate temperatures to be used when welding specific plastics. Their welding temperatures all vary slightly... So you need a machine with electronic temperature control. In some cases plastics will require 300 - 400 deg Celcius ... So a hair dryer simply wont work
@chesterjc These can weld almost all thermoplastics, so if your welding tank is thermoplastic, its very likely you can weld it.
voice is deff trippy :)
I wonder if this would be suitable for computer repair? It would need to be able to do butt joints with little to no structural integrity loss. The parts for fixing something as simple as a top panel can be very expensive to fix sometimes making it uneconomical for customers. Love the reverb and phaser on the voice, suited the DnB excellently haha big up to your sound guy!
WILL THIS WORK TO WELD KAYAK MATERIALS
a 3doodler could do something similar, with a solid weld... plus you would have a crazy fun pen to make your own 3d drawings... literally in 3d

Kindly confirm if this tool can be used for HDPE lining material about 1.5mm thick or please recommend the right model for HDPE. Is there a dealer in Philippines? Thanks.
Gave me all kinds of ideas thank you
You know this video is really old, you can now her little welding pens that work like 3D printers they are a lot better alternative to this old style Of plastic welding I would think .. but I’m not an expert so idk but I’m pretty sure the new way that I mentioned would be the better way to go
I came here for the music. but I learned more from this video about plastic welding technique than others that make a mess of things.
Thanks @LouisEmery ..
Great video
+Darrengb Thanks... we've had many say the same..
I have 2 question 1 how strong is the tack weld? 2 can the welded area be sanded smooth for re-priming and painting? I plan to use this to repair a broken piece on my hard plastic R.C. Truck and to kit bash another 2 R.C. Vehicles together to make 1 which is also hard plastic
Hi DaveStaff4, Answers to your questions - 1. "Tacking" as shown in our video has no real structural strength. A Tack is to close up the joint gaps, and to help align the two parts. 2. Yes, the completed weld can be sanded with abrasives - use a range of abrasive grits in order to achieve the required finish.. and yes, it is common to sand the parts to allow a high gloss paint finish. 3. Ensure you identify the plastic material first to ensure it is a weldable thermoplastic.

What size rotary burr (head diameter) would be good to create a V to weld 2 sheets of 3/16" thick HDPE together? I am looking at burrs and wondering if you used HSS or carbide? I tried using a rotary sander bit but the sandpaper got clogged with the plastic very quickly. I was looking into grinding bits as well. Thanks
Figure it out yourself. What do you want your hand held.
What if I don’t need it for strength and just need it to mend holes for water proofing, is this type of welding too much, and should I just instead use a soldering iron to patch the holes that I’ve made?

I have an ABS eddyline kayak that has some major cracks in it. I was told methyl methacrylate and fiberglass tape is the way to fix it. Would plastic welding be better?
I’m pretty sure acrylic will burn and turn colors
@@MudMotorsMax I fixed it with methyl methacrylate and carbon fiber cloth
@@ArcolaBridge nice
@@MudMotorsMax eddyline recommended methyl methacrylate and fiberglass cloth. But I use the carbon fiber because I think it lasts longer and it's stronger. I used my Dremel to open up the cracks extra wide so that I could Gap fill the cracks with the methyl methacrylate. Then I use 50 grit sandpaper to create a 1-inch rough on either side of the crack on the inside and outside of the kayak. Then I used a wire wheel on my power drill to put some deep grooves on both sides of the crack inside and out again one in into the roughed-up 50 grit section. I applied the methyl methacrylate to a 4in wide carbon fiber cloth and also applied the methyl methacrylate to the inside of a kayak and then applied the carbon fiber cloth coated with the methyl methacrylate onto the inside of the crack. Then I used more methyl methacrylate over the top of that sandwiched with another layer of carbon fiber cloth and methyl methacrylate and then overlaid it with more methyl methacrylate. On the exterior I filled the Gap with methyl methacrylate and smooth it out with a spatula and built it up taller than the crack and use the detail sander to bring it down smooth. I thought about covering it up with a decal or painting it but actually having a crack in the kayak sort of seems cool to look at. I might paint it with an acrylic paint at some point. I even toyed with the idea of sanding the whole bottom of the kayak and applying something like magic any foul which is a new silicone-based antifoul. Not that it needs that or anything but maybe that would be kind of cool. But anyway it took a bit of time to do this but it was well worth saving this awesome eddyline 14 sit-on-top.
@@ArcolaBridge i’m starting off with a hot air welder using a speed welding set up and I’ll be welding quarter inch HDPE into small 10 foot boats and in July I’m buying an extrusion welder right now I’m in the bed research stage because the biggest concern and the biggest challenge is stopping the sheets from warping and I do know how to stop it but I’ll keep it to myself for now
From briefly reading through the comments, I understand that this welding process makes one of the strongest bonds you can make between the mating surfaces. Are these welds watertight and do you have more info on the strength (PSI max) and can it handle being in a vacuum?
Yes, Welds can be hermitic. There is also a tester we supply for checking this called a 'spark tester'. Feel free to email me direct for more details. info@plasticweldingtools.com.au
Can this process be used with extruded plastic fuel tanks with out first backfilling them with an insert gas???
These tools use electrically heated hot air, however we recommend all and any safety moves to limit problems to acceptable levels.
I did this for a few years in a fab shop. I was required to get full fusion while keeping the rod round and prett so I looked more like the first weld. Thats poly propylene. Corzan is much more difficult and interesting process.
can this work on a grille for a 68 charger, that era of plastic?
No now sod off
Will this work on fuel pumps?
Hi gswannabe09 , thanks for your comment. If the part is thermoplastic, then yes it is possible. You need to ensure you identify the material and use the corresponding welding rod (same as the parent material)..

Why did someone apply a flanger and crazy amount of reverb on the voice-over track?
no flanger.. reverb perhaps. not sure why it matters.. the video seems to have captured a lot of attention.. so what ever works I guess.
TECHSPANONLINE for sure flanger and reverb. I've done audio mixing for over 8 years. I was curious as to why...
Sonic Moto more badassery
I can't concentrate on what he's saying, I'm just listening to the flange effect sweep up and down 🤣
TECHSPANONLINE Informational videos should not have music. It sucks.
Yes.. this welding will achieve a true molecular weld.. We supply plastic welding KITS... see the website for more details...
got a dremel tool? any small metal burr should be ok
where can u buy it from and how much?
Dear Sir, where've can get in Malaysia
I've never plastic welded before, can someone explain why you need a grounding clamp? Does the plastic need to be set on a metal surface? I figured it would be a process more akin to TIG, but it looks very different.
Hi Master Betty, thanks for your comment. No, you do not need a grounding clamp. Plastic is not conductive. This clamp is used simply to hold and support the work.
TECHSPANONLINE ok, thanks. It didn't make sense to me, since, as you said, plastic isn't conductive. I mistook the clamp.
Can it weld acrylic?
Nice video and song! Whose is this song?
Would HDPE provide sufficient protection if used to make a motorcycle mask, or are there other weldable plastics that would be better suited for that purpose?
Hi Matthew Traver, I would check what regulations in your country state. There is likely to have been approved materials for such applications. Proceed with caution is my advice. HDPE is commonly used for an array of plastic around the home. Recycling Bins, Water tanks, Wheel barrows, Milk Bottles .. even Petrol & Fuel containers.. and many more. It is easy to fabricate and weld.
Can it weld PET?
NEWS - See the Plastic Welding Tool that requires no maintenance _ copy and paste the following link to your browser. www.plasticweldingtools.com.au/new-bl-brushless-plastic-welding-tools/
The rods may look different, but they are the same material. We used a different colour simply to allow the viewer to see the process easily. In this case the parent material and welding rods are polypropylene.
Is it possible to weld PVDF to CPVC ?
+John Noone Hi John Noone, In most cases compatibility is very important. With requirements like this we suggest you try taking a slither from one part and attempt a weld on the other part. This will be the most compatibility you can achieve, so you would have to make a decision on the resulting weld strength and whether or not it was sufficient for the application requirements. www.plasticweldingtools.com.au/how-to-weld-plastics/
If only like materials can be welded, why are the rods different than the plastic?
"It puts the lotion on it's skin or it gets the hose again".
Hello I want to have a 40l cylinder tank and I have to pressurised it. Can this cylinder resist 2 bar pressure or explode? How can ı learn about this ?
If you use a spark tester after the welding to ensure it is water tight, it is likely.. but may depend on the material and its wall section thickness ..
Does this tool use nitrogen?
Do you have a UK agent, or any companies that use your equipment/techniques?
+Paul Quince Hi Paul, search BAK in britain.. we brand these under our own name here in Australia & New Zealand.. You will find a few in the UK for sure.. Hope this helps.
Thanks for info, appreciated.
Interesting; never knew they did that. I guess it replaces acetone. On the one example, the bead didn't look too good. I was a good welder in high school; both gas and arc. What does an average plastic welder get paid and are there a lot of jobs out there? I saw one available but they wanted experience. Just curious.
Hi Steve, thanks for your comment. Remember this is simply a demonstration ... In respect of the welders job and usual remuneration, It really depends what country you are in , and also on what particular welding you are doing. For example, a guy welding repairs to bumpers is perhaps more likely to earn more if he is fabricating, or welding a waterproof membrane... like a roof.
Sounds complicated! As a teacher, I'm sure a welder makes more cash. I was a decent arc welder in high school, many moons ago and an average gas welder. I retired at 50 and I'm looking for something to do. I don't know if I could weld anymore but it would be interesting to try.
John, I had good kids that were conservative and well behaved. I was lucky. I was tired of all the common core crap and I wanted to try something else. I'm only 50.
I'm over it. :-)
how well does this work on hdpe?
Hi INVISIBLE SUN , Thanks for your comment. Yes, HDPE welds very well. It is one of the more easy materials to weld. See our "how to weld plastics" information on our website.. copy and paste the following link .. www.plasticweldingtools.com.au/how-to-weld-plastics/ Hope this helps. Regards, TIM.
I have the same welder and I can pendulum heavy duty stainless steel with this system
These are welder for Plastics.. not metal..
Guys, could anybody help me out? When you weld, do you melt the surface as well as the rod? Or do you just melt the rod? I cannot seem to get a strong weld if I don't melt the surface so I might be doing it wrong. However, some plastics are quite thin, so I always distort the parent material when applying pressure with the rod... :(
Hi Farseer1995, you need to heat both the parent and welding rod evenly. This is how the pendulum welding process works.. the pendulum motion heats both the parent material and welding rod. Here is some more how to info >> www.plasticweldingtools.com.au/how-to-weld-plastics/
Can this be used to weld acrylics?
Yes, you can weld acrylic. However, this material tends to absorb moisture from the environment, so the moisture in the material will tend to 'bubble' as it is heated during welding. So if a high visual finish is required, it is not always possible to achieve. Hope this helps.
I think you should get it uploaded. Nay...I don't think, I DEMAND!
Do crosscut show weld inside
There have been a few comments along the lines of 'i can do this with a soldering iron' -- our response to this is - No you can not. These techniques show plastic welding to the highest possible strength, and to worldwide plastic welding standards as set by the DVS joining association of Switzerland/Germany. A soldering iron runs at very high temperatures and will burn and degrade plastics. We would call that 'fusing', not Welding. Weld testing will show this.
Unless your iron is adjustable..
Sorry it is not. Welding is a molecular process where the parent and welding rod and welded with almost no loss of strength. Thermoplastics require specific welding temperatures in order not to damage or degrade the material. A soldering iron will do this as soon as you contact the plastic. You will NOT ACHIEVE STRUCTURAL WELDING WITH A SOLDERING IRON.
A soldering iron still will not correctly and evenly pre heat the parent material. If you know of a very accurately controlled soldering iron.. please send me a link. The best way to solder with any such control is to use a hot air tool with electronic temperature control.. just like our plastic welding tools. Hope this helps.
My Duratech ts-1564 has served me well on all of the welding i have done (HDPE) though I did make up a tip for it on the lathe/mill so I didn't ruin my good electronics tip, which wasn't really suitable for welding anyway.
Hi 74KU, if you are only 'fusing' and do not require structural strength great, but if you want a structural molecular 'weld' the use a Techspan plastic welding tool every time. www.plasticweldingtools.com.au/product-category/plastic-welding-kits/
Dear. friend. Please. Explain. Hot. air. Plastic. welding. Systems.
Hot air plastic welding is the process of joining two or more plastic surfaces together using hot air, usually applied by a heat gun. Plastic products can't always be made in one piece. It is often better and more economical to fabricate products as separate pieces.
sounds like "bal sagoth - plastic god"
Oi your voice is cool :)
hi, there can you please let me know if there is machine or any way to weld plastic HDPE2, thank you.
Hi Paulo, thanks for your message. I recommend your buy one of our Rod Test Kits. It contains some 40 different thermoplastic welding rod sticks. You can then carry out your own Test Welding Trials . Here is a link explaining exactly how this should be carried out >> www.plasticweldingtools.com.au/how-to-weld-plastics/ Hope this helps.

Custom tune... glad you like it :-)
Thank you. Exactly what I needed to see, 90 degree inside corner plastic welding.
Nice voice
Where is it available. I need it an argent.
The engine is too hot the results are not so good PP takes a lot of pressure
Will it work on polyurethane
Yes, PU (Polyurethane) can be welded, providing you use PU welding rod. You can also use part of the parent material as the welding filler rod. Otherwise we can supply PU welding rods. If you need these please email us at sales@techspanonline.com
Hi John, these are different materials, so you should not expect a good result. While you may see 'some' kind of bond, you will not be able to effect 'good' welding. We can supply both PVDF and PVC welding rods, although PVDF is not listed on our e-commerce welding rod website. For ordering suggest you email me direct at tim@plasticweldingtools.com.au You will find the PVC rids here 》》 www.plasticweldingrods.com.au Hope this helps..
