How to TIG weld aluminum beverage cans together
Ғылым және технология
I show how to weld aluminum cans together with a cheap import TIG welder. I am not a professional welder, so some of my advice may be unconventional or even wrong, but these methods work well for me. With a 3/32" electrode and large gas lens, I don't have to change the torch setup for nearly any kind of common welding. Let me know if you have any questions or would like me to make more welding videos.
Some things that I have learned:
Don't use pure tungsten electrodes. The new rare-earth blends work very well on nearly all metals.
Sharpen the electrode to a very fine point for low-current welding, and sharpen it like a pencil for higher (eg over 100A) welding.
Keep the electrode balance control electrode negative ("weld") and only shift toward electrode positive ("clean") when absolutely necessary.
The welder's pulse feature turned out to be not as useful as I originally thought. It just seems to complicate things. It's definitely possible to make great welds without it.
Use fat electrodes. Some people claim that using an electrode that is "too large" for the weld current will cause the arc to wander. Nope. Just grind it to a sharp point. Thin electrodes 1/16" and .040" overheat much too easily, and provide no apparent benefit. .040" electrodes are very frustrating.
Use thin filler rod. It's much easier to feed thin rod quickly than feed fat rod slowly. As I mentioned in the video, it's easier to sneak a thin filler rod into the puddle while keeping the torch close to the surface.

It was a cheap welder with likely no warranty, so you either fix it, sell as unoperational, strip for parts or throw out. if you have as much as basic electronic knowledge and saw a few pcbs in your life, and know how to use a soldering iron, those problems are beautifully simple. If he had a more common fault for cheap devices, a failed underpowered semiconductor component, I would expect him to abandon the welder for at least two weeks, and take quite some time figuring where the fault was, since it was "two days" for easily visible/audible faults. He is absolutely a man of great knowledge, but this particular case is not a showcase of unusual ability.
My wife accidentally tore a piece of aluminium foil, I tig welded it back together. Stuff is to expensive to throw out.

Very nice video! As a welder, I have a couple of tips, though. Wait for the puddle to drop before adding filler wire. This can be tricky, because as soon as the puddle drops, you can burn right through the material, but that puddle drop is where the penetration in a weld comes from. Also, making a side to side motion (relative to the seam) as you push the puddle will ensure that the metal flows evenly and makes for very pretty welds. Keep making great videos!
good job bro...ive been a welder for just over 10 yrs and I know guys that couldn't do that on there best day that have been welding for 20+ years!
my entire life i have been searching for answer to the age old question of how to tig weld aluminium cans together and now i've finally found it. Thanks Applied Science!!!
my god! watched a lot of welding videos and this is by far the best video of actual welding you can see everything it's amazing every welder on youtube should do what you do !!

Very impressed by your clear and calm voice. You are an excellent teacher. The video from the welding was also extremely good. It was very easy to see what you very doing and what was happening. You really deserve a better machine than what you had there. Thank you and hope to see more from you.
I have around 20 years of welding experience and can stick, mig and tig equally well.. And we all stick our tip in it, once and a while.. It's nice that he shows that it's not the end of the world.. just re-dress it and start over.. And proper setup always takes much longer than the actual welding.
Ben, Thank you! Always informative and edifying! Even though you say you are not an expert welder, your knowledge of materials and the process makes this sensitive weld possible. Many good tips and lots of useful info here! Much appreciated!
For the prettiest weld possible, try this "lay wire" technique, it's much easier once you get used to it: kzread.info/dash/bejne/gaVqp7CSk5ibeJc.html

@@DanDishonored Agreed, there's a lot more going on there than shown. The results look nice, but it also seems like the tip dips into the weld at almost robotically intervals. How do you keep the weld working correctly if that's the case, and how are you keeping the weld so uniform? Almost looks like a robotic setup. Either way, impressive work. We just need more detail.
Good one! My cheap tig welder from China had a cold solder joint on one of the capacitors and made a very loud bang when I first plugged it in. Easy fixed though. I'm a welder and metal fabricator by trade in Australia, 15 years experience. You've done really well for self taught.
Best video for TIG welding! very well done . Thanks you!
I have some aluminum pressure tanks from some aerospace projects that have thin metal like that. I always wondered how they welded that paper thin metal! That is really a great demo you did!

Some people online just roam between places telling people they are wrong, without saying why... just so they can feel clever/smart/superior. You can always tell them apart from a genuine person, by the fact that they simply state you're wrong, without even saying how/why.
I just started playing with a TIG this week. Great tips, thank you.
Great video I could not figure out how to make this fit my torch head until I saw you say it went on as an adapter WOW I just stopped the video ran outside and it fits perfectly, Thanks a million... A+ my brother

Thank you for this video. I've did some tig welding years ago. It was hit and miss, Ithink I was always too hot. This was a very informative post. Thanks again.
Your then only welder that actually know the internal components of that welder, and knowledge of electricity.
I am always impressed by your knowledge and presentation skills in all of your videos. Please keep producing more videos.
You make it look very easy. I'm going to try this sometime in the future when I have some extra time at work.
I have been tig welding most of my adult life and just wanted to say that you are an excellent instructor with lots of attention to details and your thorough explanation is much appreciated. In my opinion, you grind your tungsten backwards but aside from that - Bravo and Thank You!
Idont know about the welding part but you had mentioned about the lighting which I find extremely efficient and good, Perfect lighting way to go

It was truly amazing lightning. Don't think i've ever seen a welding demonstration where the exposure showed both the spark and the material. Didn't know it could be done!
I don't always watch Ben Krasnow weld aluminum beverage cans together... but when I do, I'm procrastinating from EMF homework
With the way you hold the torch close to the time, I immediately saw the opportunity for a redesign of the torch to eliminate the handle you don't use. Turn it into a simple cylindrical torch without the handle extension. Cool hand hold
wow , this was seriously amazing , those cans are so thin that they will be ruined easily , yet you managed to do it
my first welding teacher showed us this, i was amazed.
Thanks a lot for putting out this video! I have never tried TIG welding before, so it's really interesting for me :)
I think it is great that you spent the time make this thank you
I like how you have an obviously well equipped shop and yet your welding table is a table saw.
Thanks for this! Just learning how to weld, and I'm really impressed abt. what you do!
Thanks for the effort Ben. Nicely done.
Impressive. Never been that good at welding. If anyone would like to know how to burn through an inch of steel plate whilst trying to weld two of them together then I'm your guy.
Cool video. I have never TIG welding nor have I seen it done so thanks for sharing!
very very good video,thx so much for sharing your knowledge!!
Best filming of welding / arc out there - Jodie needs to learn a thing or two from you on how to film the arc!! and this was 8 yrs ago!!!!!
Advanced modern inverters can make this look pretty easy in the right hands. My everlast makes me look better than I am LOL. Thanks for the video and the tips.
Good instructional video. I had the pleasure a few years back to watch a guy I work with tig a coke can that was cut in half back together he tigged the the very thin material with very little prep, I was gob smacked to say the least. It is no surprise to know this gentleman has his handy work in space.
The best explanation of TIG I've seen yet.
very clear, informative and clean nice video!
you did great at explaining everything thank you. You should teach if you don't already
Fortunately for the rest of us, the noteworthy stuff doesn't care one iota about what table you welded it on, or even how much money you spent on the equipment. Sometimes it's the combination of ingenuity and what you've got that counts. I've seen plenty of truly amazing things done with "improper" equipment, on a shoestring budget. Not willing to spend all of one's money on tools isn't laziness, it's simply an indication that we have life besides our tools. Not all of us are tool geeks.
Nice vid! I don't know too much about welding, (too say I'm an amateur would be doing amateurs everywhere a disservice!) but I'd have never guessed you could get the heat low enough to weld cans! Very informative. Thanks for the vid!
Great job. I have done it My self and its not easy, but fun to do on a friday evening having a couple of beer or two!:)
This just gave me the best idea for a bong ever
PS again Welding for 44 years, stainless and non-ferrous metals, ALL processes, B-Pressure piping and vessels, aircraft repair, pipeline, structural and oilfield.. Taught Journeyman Apprenticeship Trades welding in College for last 8 years. When GTAW ferrous metals, you can save a lot of time sharpening by using the acid dip, which will sharpen tungsten quite adequately rapidly, with out leaving your weld position.
Very Professionally done. Excellent.
Thank you for putting out this video. To date it's the best one i've seen that shows the puddle and the weld as you would from behind the mask...
Looks really good. Nice!

You want the end of the tungsten electrode to be more rounded, or ball shaped when welding aluminum. Great videos. Thank you.

Those aluminum welds are beautiful. I don't have a TIG welder, but I've seen the Henrob 2000 (which I plan to have) weld aluminum remarkably.
good job on the welding
Yes! More welding please! Much more!
A little tip to get your tungsten really sharp is to put it in a drill and spin it as you grind it.
Fantastic video, the camera technique is awesome. Its the best video of welding I've ever seen.
I've noticed the hand-held torch and plasma-cut switches do not work properly. The machine must be attached to the foot pedal control, and the pedal must be depressed for proper action -- even for stick welding! I'm pretty sure these would be fairly easy to fix, but I only use the machine for TIG, and I always have the foot pedal connected anyway.
Huge gas lenz are a must for stainless , but alluminum #6 more than sufficient, but doing what you were doing all good. Thats a sexy back purge set up very nice.
If I ever get that good a welder I will feel like an accomplished human being :)
Hey Ben. Many thanks for this informative video. I have a machine similar to this one and I'm always worrying that it will develop an electrical problem which is beyond my ability to diagnose and fix. Can you tell me how you diagnosed the bad solder joint and the spark gap? What process of trouble shooting and analysis did you go through? I could never pick up on something like this with such intricate circuits in place.
Thanks Ben! Great video
thanks for your very clear explanation, 1th class video!
stray arcing due to sharp tungsten, try balling your tungsten using a piece of copper switch your machine to DC hold your torch 90 degrees to the copper piece and light up on it, you will see a ball begin to form, make it just over the diameter of the tungsten you are using and try using 100% pure tungsten (green) instead of a blend.
The way that ended so abruptly reminds me of that birth control method, weldus interuptus.
Nice job. Highly informative.
I'll weld my beer cans. As soon as first one is over I'll flip to the fresh one and enjoy my drinks. Thanks a lot for ez hack. 🤣
Great Can do attitude, good work.
I see that you are using a pointed tungsten. The norme as I recall, been many years ago, am not retired for 20 years, the tungsten is usually blunt and pointed for the stainless or carbon steel. You are doing quite well with the pointed tungsten and have given an excellent demo on this video. Well done!
I'm interested in your camera setting and shutter speed, I try ti film through a lens and it doesn't work as well as I'd like
You're on your way to making the worlds most rugged solar heater panel.
Your multitude of skills and interests are impressive ^_^
Those who don’t know what’s the point: tig welding thin aluminum is very hard. This is a nice job.
Video is very helpful, Thanks, may i request u to send some more information about Current set and about the Filler rod , I mean the blend in detail
Awesome video quality!
If all you know how to do is welding, then yes, availability of spares is an issue. This is Ben Krasnow we're talking about. He could, if there was a need, manufacture or adapt pretty much anything in this welder. If he wanted to keep this machine around, he could do so "forever". That's the nice part about having wide-ranging skills :)
Great video! Thanks.
*Tig is ART bigtime*
allows a more fluent current and a more accurate and precise arc

I am glad you talked breifly about the oxide coating on the aluminum. its wicked crazy the oxide coating has a 2300 degree melting point and the aluminum itself is barely 1300 degree melting point.
great video, looks like fun

welding starts at 10:49
good clear video! Many thanks!
Great effort , thanks for posting ..For Ali you need Zircon (AC) electrode, 1/16 " is best. This needs to be balled via high amperage on another thicker metal. Sharper thoriated electrodes (DC) are best for ferrous based metals only. You will notice that the arc pulls to one side then to the other but never to the join. Ball tip will alleviate this and less filler will be used.
This is awesome, I'll say that, thank you for making the video, but I've been getting into welding(currently in a course for it and doing well) and I've heard on multiple occasions welding alum. that you want a round tungsten tip, not pointed like you would for steel(s) and other similar alloys.

You still need to chamfer the tip. The reason is to do with the current, not the material being welded. AC is usually used for welding refractory metals such as aluminium and magnesium and this alternating current melts the tip into a ball.
GREAT VIDEO!
Thanks Ben, good trouble shooting on the welder. Rob
A good habit to get into is to acetone wipe your parts before wire brushing. This keeps any grease or oil from getting scrubbed into the work by the wire brush. After wire brushing a blast of air is all that's needed for cleaning since the only contaminant at that point is the dust from the oxide layer.
