Thanks for watching! I've make a playlist of my favorite woodworking projects: ua-cam.com/play/PLhqK_8dnaIW3V6a66AdyRI9DJUZwCSm83.html
will this work for a steel muffler, with small holes?
Just a note, when brazing, the filler rod will always flow towards the heat. Had you clamped your setup vertically and gotten the joint a fair bit hotter, you could have drawn the molten filler towards the torch. could make for a significant;y stronger joint.
I’m not a welder, I’m a mechanical engineer. It really depends on the application, regarding the weld strength. Everything has an allowable stress; In the case of a full penetration weld, of course it is stronger than what is shown in the video. As an example, if I wanted to make anything that is structural, meaning to AISC standards, the soldering methods in this video would be a death trap. But if I am making an aluminum picture frame, the aforementioned would be a great bonding technique. No sense in attacking this guy, he’s done nothing wrong here IMO.
Brandon, where can I find information on the strength of aluminum brazing applications. I like this method. I'm wondering what are the safe upper limits of the techniques. For instance can it be used to build an aluminum bicycle frame? I ask because I think I remember a guy doing just that in a UA-cam video a while back.
@@sentry9834 No way. Bicycles have to endure impacts from bumps. It's very different than a static load. The last thing you want is your bike falling apart as you speed down a hill.
Creative Thinker Oh god no bud
@Hero Walter de Haan big difference between soldering and brazing and what this guy did was below the heat of brazing he basically soldered those Al tubes ,idk why he even called it "welding" in the title and then said "brazing" in the video which is also wrong, no where near that,,and I'm a welder
Creative thinker HAHAHAHAHAHAHA hilarious 😂 be like buster Keaton, imagine all his family and friends watching his first test ride of a bike he took months to build and it all falls to pieces LOL HAHAHAHAHAHAHAHAHA he'd look a real sad act 😂
This process will not work outside in breezy conditions. Aluminum cools very quickly and melts at a relatively low temperature. For better results work on a ceramic topped table with a ceramic tile behind the metal you're working. Try to place ceramic on the sides also. This will reflect a good portion of heat which will otherwise dissipate very quickly.
Great tip!

I used to use a similar product called Lumiweld. It was a fantastic way to repair ally engine mounts and cracked casings in situ. Nothing short of a bloody miracle..
Good video. I like your method.
As a maintenance technician, I have also used these (only when necessary!) in an industrial environment. I would advise against using these in any situation where high strength is needed. Only use these when you need a very light duty, low stress joint. They don't hold up well to vibration or in a load bearing capacity. Additionally, don't use them to stop leaks in aluminum tanks where you have a lot of water pressure. They don't hold up to that very well either.
FLUX IS THE KEY...
After seeing your video, I bought a MAP torch and the same Bernzomatic brazing rods you used. But no matter how well I cleaned and prepped the aluminum, I found the strength of the brazing disappointing. The 'solder' just didn't adhere very well to the aluminum.
I then watched the YT video by Vulcan Systems showing their "G-51" flux + brazing rod demo. So I purchased their product to try it and compare. I just got it today, and as my control test, I used their powder flux with the Bernzomatic rods.
HUGE difference. I cannot rip the two pieces apart with a vice and pliers. It's just like in their video--extremely strong--effectively like a weld.
Besides the obvious benefit of producing much better adhesion, the flux is nice because it changes from powder to paste, then to liquid when the aluminum gets to the right temp. No need to guess whether its hot enough.
Also, the flux helps to produce the capillary action they show in their video--the solder just flows into the joint, whereas without flux, the solder seems to just sit on the surface or edges only.
I highly recommend picking up some aluminum brazing flux if you do any more Al brazing. The improvement is incredible.
Based on the quick shopping I did, the Vulcan G-51 flux + rod kit was a pretty good price--certainly much cheaper than the two rod package sold at Home Depot.
I used to work for a company that Brazed fuel lines for International trucks. The sweeping of the brazing rod across the joint isn't necessary. Once you get used to it you'll be able to tell exactly when the metal is the right temp and you just take the brazing rod and set it in the center of the joint and it will flow on its own leaving a perfect seam.
+DaTwistedOne1 These rods are designed to be wiped or scratched to remove the oxides that form almost instantly on the aluminum. There are other aluminum/flux combinations that may flow like solder on copper, but this isn't one of them. I've used this stuff quite a bit and you HAVE to scratch it to make it stick. Look up the instructions or videos for any of these alloys. This stuff is very strong(much stronger than the aluminum itself). You can tin the mating surfaces prior to fit up or scratch on a heavy fillet or bead to increase the strength provided you scratch it up an 1/8 inch or so on both sides of the joint. I generally go twice the thickness of the material on both sides. Or you can fully bevel the joint to a knife edge and fill it in completely, but you may still not be able to scratch off the oxides to full depth.
I have the welding equipment due to health problems I can't weld with electricity any more.
As a plumber this really excites me...the possibilities.
That was excellent. Thank you for getting straight to the point. Clear and informative.
6 years later and your video was still super useful - I didn't know I could do that! Thanks for sharing.
This is an awesome tip, David! I had no idea that aluminum could be welded without an expensive AC Tig welder. Definitely going to use more aluminum in my projects. Thanks to people like you, sharing free knowledge, humanity is less dumb every day :)
This is awesome - being able to work with aluminum like this opens up so many possibilities!
Toolify it’s not a strong joint
I am late to the party, but that's amazing !
What are you doing here?😅 Always felt like sauces and beers were your thing, not weld alternatives

These brazing rods actually work pretty well once you learn the right technique, it makes a surprisingly strong joint. Really useful for repairing alloy castings like the side covers on bike engines.
Talking about inner primary covers? I got a small hole in one
@@FranciscoMartinez-dg2ku Yep would work fine for that, you need to get the area very clean and you need quite a lot of heat input on a larger casting.
Which Brazing rod u r using,mention please
I'd suggest using a good flux to ensure you get rid of the aluminium oxide on the metal surface and filing a bigger bevel on the tube ends to get more filler rod in the joint.
I've always wanted to get into metal sculpting for making art, but it's always been too expensive to get a welding machine. This method allows me to try out sculpting in metal without too much of a "start up cost". Thank you for this! :)
Invest in safety equipment. More than anything, a respirator, goggles, and welder's gloves. Those three will be no more than $100.
Use the smallest clamps and as far from the weld as you can. Aluminum transfers heat quickly so youll be heating your clamp to surface of the sun levels while the work is still too cool. This is particularly important when brazing a second joint next to or very near an existing braze. If you have clamps pulling heat off your joint it can pull it thru the other joint already done and cause it to hit temp before you're ready inn the part you re working on and next thing you know, you have aluminum dripping out of the other joint and it all falls apart in front of you. The temp needs to be just right...not too hot to release other work abd not so cool it takes forever and doesn't flow. If it looks ugly, heat it up again and get it to flow. You can even use w small screwdriver or something to swipe thru the puddle to get it to lay right. But don't get crazy. And dont keep pushing stick into the weld and make a big mess of it either. It doesn't take much. And remember the stick melts quicker than any material youve already laid down and If you melt stick into an existing welding will melt right away. Heat the work to tye point it will melt the stick and it will pull it into the joint. Don't just blast the stick with the torch because it won't flow into the joint and the work wont be hot enough to make it stick as good as it can.
Biggest thing to remember is to keep clamps away from the joint if possible and if your work can be clamped to something to support it with the clamp being 6-10" away, you're golden. All your heat will stay where you want it. Anything the work is sitting on or touching it within 6-10" is sinking heat from the work.
Amazing! Thiers nothing better than an honest instruction video! So far this seems like the most straight forward video. Nothing worse than buying a bunch of junk because thiers videos that make you feel you can't go without. I will try this method and see how this works!
Awesome!! A thousand new ideas for new projects with this video!!
Hey so did you build something interesting using the method from this video ?
@@AuroraCypher It's so soon! Wait more ten years at least. :))))
thank you for this video and tips! I'm a diy queen 👸and this year the skill I wanted to add was beginner welding and this method will work perfectly for my tiny home conversion build where I'll use this method to repair furnace removal in the aluminum siding of my vintage rv and patch it! I'll also build a aluminum frame to house my generator I'm test the strength of course before using!😊
This proces is not exactly brazing, the rods used are from a firm called Technoweld. The process is actually more than just brazing, there is a chemical reaction between the welding material used and the alloy. If done correct the joint is pretty strong.
If you want to make the joint even stronger than the weld demonstrated here you can scrape the weld with a thin stainless steel needle, this will mix the alloy and the welding rod even better, making the chemical reaction work better. Personally I have made welds using these materials which proved to be very strong indeed. But no they are no math to the real thing hens MIG and TIG welding. Never the less, when done properly the weld is really strong, not to be confused to soldering.
Brazing materials can in some cases prove to be stronger than welding, because less heat is used thus avoiding stresses and crystallization.
would this method in the video be able to hold up to 200 lbs of weight?
You can look up the tech. info on the Techno Weld UK website. But depending how good you make the weld 345 N/mm2 is possible.
Michael T.
On the table of the video no problem with 200 pounds. It's very light square alu tubing, enough for a small table but not intended to have a 200 lbs cossack dancing on at the sound of the balalaikas.
Michael T. Pm
Interesting. A great solution for those of us who want to make aluminium artefacts but who also have a life which does not involve obsessing about becoming an expert on TIG or MIG, whatever their benefits to ones ego might be. Thank you.
Pro tip (from a welder) only heat the path you want the brazing to go on. The heat will create a path for the brazing to follow.
+Joshua Walters Ah ha!! Thanks for that tip!!
Make Something
hunti cunti Wow your such a troll!
Fuck you... he's right.
the fuck is the negativity for? he gave the guy a tip without any passive aggressive bs. lighten up man
I made a small tool to help in making a clean and strong joint in aluminum; I used a 1/8" Stainless Steel rod, flattened at one end like a screwdriver, and inset into a wood down for a handle. When the joint is initially formed, I use this took to scrape the base aluminum to remove any oxide layer, and to merge the brazing rod deeper into it. I can also use the tool to draw out the fillet and make a nice clean bond. Keeping the torch on the joint helps in the operation. One thing to remember - the brazing rod is a Zinc-Aluminum alloy and does NOT wick into the joint like a 'solder'.
that's cool ! ,it's something I would never have thought to do but now I want to try it !
Neat. This is all new to me but it's something i'll use in the future. I checked and it's widely available on our side of the ocean (that's Europe and Holland in particular). I remember hard soldering copper in school many many years ago and it looks like it's exactly the same thing but with different materials.
Thanks for bringing it to our attention since it's been around for quite some time and i've never heard of it.
Take note everyone, he was wearing a respirator. Make sure you buy the right filters. Brazing/welding aluminum can be bad for your health. Great 👍 job brazing. It was very brazen of you? 🤪
True, tho’ back in my school dayz when we had metalwork class….no ppe period, not one bit. We used lathes, milling machines, gas torches, even a forge. It’s a wonder we survived!
The guy talks funny, but the video was short and direct. thing i like. Many youtubers make a video of about 10 minutes with something that could have been done in 2 minutes if well explained. Thank you "Make Something" Guy. you got a new subsriber.
Boy could i use a strong joint right now
next best thing, stick a thumb up your bum.
@ That's a butt joint !!!
When it's cold outside I usually stick my thumb in my bum and holler "SNAKE!" just to get it to come out where I can grab it to pee...
Move to Washington it's legal
@ mknnk n n mlmoo
ive used a few products ( different brands) same thing, i can tell you it works better than anything other than a TIG.
the trick is to build it up after you do what he did, also get a Stainless Steel brush and tin ( thats brushing it on before you finish)
Once its done like he did with the tinning step, let it cool down a bit and you will find you can build it up like semi hot wax that is not liquid yet, then when your happy with it get a tiny bit more heat to let it flow just a bit but not all turn liquid. then grind off the excess. i have used this on lots of items including racing parts.
These joints could be strengthened significantly by bending short tabs inwards on the cut tube to create more contact surface for the brazing material. It also makes the brazing process easier by moving the cut end of tubing away from the flame and allowing for more heat before melting the aluminum.
Probably the best tip I received yet. Thanks!
+Make Something One thing that should be taken into consideration is that certain alloys will crack when bent unless annealed beforehand. So a test may need to be done to check if your tubing will take a relatively sharp bend without cracking. If not annealing for most alloys can be as simple as heating to brazing temp for a short period of time and allow it to cool slowly before bending.
+Siegfried Gust What "short tabs" are you referring to? Are you saying make small lengthwise cuts on the corners of the tube and bend those?
+Slap Stick Yeah, you would need to make some v-shaped notches in each corner of the cut end of the tube. And then bend them inwards till they form right angle with the tube.
Siegfried Gust I see. Thanks. Would the brazing material flow all the way to coat the entire 'tab'. ?
great tutorial. takes practice but it works well. I used to overheat and end up melting the tubing but this is a very good technique. Also, brazing is very strong, not like welding but can be stronger than using rivets or screws. Thank you!
thanks David, this is something I can do, even though I don't have a welder. Great info!
+Paul Meyette Thanks Paul!
+Paul Meyette Same exact thinking here too! Love these types of videos where it's something completely different from my main hobby that I can then incorporate into my furniture making.

*I love how you will use some of your old projects with the ones you're currently restoring. Well done*
That is a very useful information.
Thanks for sharing.
Nice video! I will have to try this. This is a good reason to keep old tools around. When I bought a new compound miter saw a few years back, I kept my old crappy one in case I ever needed it. I now find myself just keeping an old junk blade on it for cutting miscellaneous stuff that I don't want to risk on my good saw with my good blades. Comes in handy as I find myself using it to cut materials from aluminum stock (like in your project), rain gutters and downspouts, to pallets (in case there are nails hidden it won't ruin a good blade). Great job...keep up the good work!
+Dewy Russler Thanks Dewy!

Thanks for the UA-cam video tutorial. Perfect timing for me. I am assembling a Harbor Freight aluminum Ultra-Tow-Trailer and plan to make fold-down side that need to be "welded" as a one-piece unit.
I love strong joints!
Chronic, is a strong joint. LOL
Strong joints of
What ?
Pray tell ...
Since then I have seen aluminum welding vodeo, I will learn this and guide for my friends,
really cool. when you are ready for tig and stick welding... try the AHP machine on Amazon can't beat the strength of a weld plus its cheap and works great
All of the negative comments are interesting. I agree that there are some who come here and claim to be welders with 100+ years experience and having to walk miles and miles in the snow up hill both ways.
As a part-time missionary, I have done both ways, I brazed aluminum engine parts when I didn't have a Tig machine. The only difference, I used brazing flux which allowed the aluminum rod to flow better.
The piece has to be surgically spotless, meaning any oil or grease has to be baked out, then cleaned with the best cleaning solution You can find to bright shining metal. If the piece to be welded is a casting, it has to be preheated to 400 or 500 degrees. Then welded hot, then reheated and cooled slowly. Overlap joints hold better than butt joints.
When You have a crucial vehicle down and replacement parts are 200 miles away or have to be sent from the States, taking weeks, You do what You have to do.
Having said that, JB Weld repairs a ton of things. Even after repairs, JB Weld is spread on the inside of the piece to prevent leaks.
Gooddtu
This is brazing, not welding, welding fuses the two peaces of aluminum together, this is just filling a crack.
+William Seroyer LOL Harsh but true ! :)
+William Seroyer so welding is fusing two pieces of metal together?
Brazing does the same thing--it also--- fuses ----two piece of metal together.Filling the crack with heated metal---still fuses--the two metals together.
In brazing you have to be more careful with the heat.
In welding--the heat is not as critical as brazing.
+Johnny Wewoka the difference is that welding actually melts the material, and adds more molten material, where as here he specifically said not to melt the aluminum. and try not being careful with your heat when you're running an overhead welding bead. You will regret it instantly.
TomB205 I agree LOl you said it much better.
+Johnny Wewoka Think of this as soldering aluminum together.
Thank you, this will be my first try at welding anthing.
I tried 20 times . no good . so I just went out and bought a coffee table .
Thanks David! I had no idea you could braze aluminum. Great tip!
This is brazing not welding. Don't lead people to think is the same. It's not.
I agree!
Good thing he quoted weld in the title to show that it's not real welding.
...Right Stuart Conner, NEVER fly an airplane soldered with this system.
Have a nice day.
Stuart Conner this is very ironic, its not brazing either idiot...
OK, I must say in any case, that this vid is a fine tutorial of how to complete this process NO MATTER what the actual process itself is called(and seems to be the subject of GREAT debate!). So that being said.... GREAT job in making the video and showing many folks how simple and easy it is to actually do this. Kudos to "Make Something" and thanks for your efforts- I subscribed!

@@noneedtoknow6098 No, it's not welding. Brazing doesn't melt the base metal. Welding does. Brazing is akin to soldering.

i used those aluminum rods to fill voids between the combustion chamber and water jacket on an aluminum engine block that had blown the head gasket . back then the rod manufacturer recommended working the bare metal with a stainless brush and a bit of welding rod. repair was totally unnoticeable and lasted the life of the engine.
as a welder this is gross
they make plastic connectors for 1"" square aluminum tubing if you can't welding it buddy.
Good point, buddy.
a welder can't make youtube comments... you're a human
Thanks! The welds on my walker ( I know, I'm really really old) are coming apart. Holding it together with zip ties is likely a bad idea! Now I can fix it! Yippee! Thanks a bajillion.
Since Map gets hotter fast, is there a reason why you are using Propane?
Reply
To show you can use either. Reply
They quit making real MAPP in 2008. The "MAPP Substitute" gas isn't much better than plain old propane - if you don't want to deal with acetylene try an oxypropane torch.
It's plenty strong enough to provide static support. good job.
It's been holding up my coffee table for over a year now. Think positive!!
something like that does not seem to be strong enough
SuperTheseus Did you watch the update video?
I've tried this .....works .....does take practice
I just had a strong joint
this is pretty amazing. Aluminium melts at 660 deg C, but obviously, the thin stick melts much earlier than the aluminium tubes. thumbs up.

my favor aluminum on my any R/C hobby model...
use a drill / a die tap / bolt or screw...
no no electric welding / no no gas welding
If you are uninitiated into the world of brazing then you might search for a term like solder or "weld". This isn't click bait. This terminology was simply used to help make others aware that this process exist. Calm down children.
Thanks, I never knew about this.
A professional welder will cheer up somebody not critisize somebody. Its good to know about the difference of brazing and welding anyway. Thanks for the maker of the video never mind those uneducated attitudes people keep it up :)
This doesn't need a welding helmet on to do right?
no, but some safety glasses are strongly reccomended....
+Shaq Deisel hahahahaha.
+Shaq Deisel lol
and the dip sh#*'s have spoken. she asked a simple question. friggin 12 yr olds
Just a tip. Map gas only burns a little over 100 degrees hotter that propane. Map pro in the yellow bottle is not the same as the old Mapp (2ps) gas. Unless you are adding oxygen, it is the same results to use the blue bottle for a project like this and it's cheaper
Funny how youtube is filled with no it all's on every subject. This method has been around for years and it's surprisingly durable. It used to be called Aladdin Metal because it flows like magic. I've fixed a lot of stuff with it everyone and it's strong!
***** You ever held a wrench? Alladin Metal, again works great. Not as well as Tig, But well enough to repair a propeller or skeg.. Quick google what those are :)
You are basically gluing two pieces of aluminum together with this process and no ware near as strong as a penetrating weld... Ok for household crafts but not for automotive or aircraft ..
Highway Star It's a true "Braze" actually. And no I am not a sales person but evidently I should be... The zinc rich alloy rod scrubs the oxide layer from aluminum and allows flow...
And yes of course this is not aircraft quality welding, but I have used it for fixing marine propellers, skegs, water pump housings etc.. It sticks "Like a glue" but it's a metal that can be machined. This is called brazing.
TIG welding actually "Burns" into the base metal. This adheres to the surface (brazing).. Bike frames, radiators in your car, HVAC lines, carbide tools are brazed and seem to hold up pretty well.
fla playa brazing is basically just gluing 2 parts of metal together and has no penetration into the metal. Ya it holds but not for heavy use and that is why it is not used for a strong joint. It is old world work and obsolete in many productions.
Highway Star Brazing is in between soldering and welding. Solder two copper wires together and try and pull them apart...
This is excellent, I'm going to try that on my CAFE RACER BUILD!
👍👍👍
Thanks for the tip. This is quite interesting for people like me who don't own a welder. Did you tested the joint? How strong it is? Thanks again and regards from Barcelona!
+Woodworking Barcelona it won't be very strong, the way this works is more like a glue than welding. This uses aluminium rod to fill a gap, welding will melt the two pieces of metal together so they become one.
+rparker069 I believe this kind of method is called 'brazing'
+Fire Crow's Workshop brazing is done with brass and flux c;
I'm fairly certain this is soldering
Yup, this is soldering. Difference between brazing and soldering is melt temperature of the filler, below 840°F is soldering, above is brazing. Brazing is not necessarily done with brass, silver and nickel are also used (although likely not at home lol).
As for strength, it is capable of very high strengths if the joint is designed properly (just like wood working). This butt joint, however, is not going to be very strong. Lap and scarf joints can be quite strong, but with square tubing there aren't many options, except maybe to scabb on another piece to bridge the connection
+Woodworking Barcelona This is not welding - it's brazing, if not soldering.
That is awesome!!! I have a couple ideas for using aluminum in the shop for a couple shop furniture projects but didn't know you could weld it like that... so many ideas!!! Thanks for sharing!
Wow. I wonder why people buy TIG weldingmachines for ton of money....
Maybe its because they actually weld and do not solder? but what do I know...
Solder and brazing aren't welding. It is a good thing because I hope to make a lot of side money with my everlast tig welder. Seems there are quite a few people who need to actually WELD aluminum.
That does not change the fact that you soldered it. Its not even close to welding...
More likely to soldering process...anyway, what is the different between solder and brazing?
***** Fahrenheit.. I love that unit. Just plain stupid.
But thanks for teaching me a new english word :)
@ Buck, it's been pointed out that ''Brazing Rods'' melt at 370C = soldering.
brazing by definition = temps above 450C...
think abou it ;)
Good job, I am sure their are alot of ppl. That will Try it ,it is much easier than most ppl think
isnt this more like soldering? nevertheless, cool technique!
Its brazing which is basically soldering, the only difference is the strength.
+Daniel Napast soldering is the lowest temp, brazing in the middle, and welding is the hottest joining process.
You can solder aluminum using products tinman sells based on products
used in aircraft manufacturing in WWII. You can't braze aluminum
because the melting point that separates brazing from soldering, melts
aluminum. Plus you have to deal with heat treatment post braze, if you
brazed it.
It is a shame that people cannot just enjoy a video without making an A** of themselves!
:)
I know. It's horrible
I could not agree with u guys anymore, too many haters without a clue, but quick to pull the trigger... i would love to see them make a video themselves on how they do it... and post our comments :)
The point is that people don't just enjoy the video because the title is luring into watching it because it shows how to "Weld" Aluminum Without a Welder. If he would just have called it "How to braze/solder Alumnium if you don't have welder", I wouldn't have watched the video in the first place because I already know that. The video is perfectly fine, but the title is a clickbait and that makes people mad.
The title is based on what people would search for. But great guess! Thanks for playing!
I did something like this many years ago to make a backpack for boy scouts troop. I used electric arc welding rod with small buzz box 120 volt welder , worked very well.
"Map/Pro" is not MAPP gas. Don't encourage that scam.
he didn't say it was. Nobody makes MAPP gas anymore.
Love this Channel man, just from the first video. Solid information presented in a way that is easy to follow and not too lengthy and boring. Thumbs up, I just subscribed.
Should we change the title of this video to something more appropriate? We could call it, "Joining separate aluminum pieces with an attached 'Right Fight' commentary".
This is awesome. Could you do another video to see what it takes to break it? You always have to know the strength of new processes.
i came here for the joint
ohhhh its a different kind of joint .. nvm
c:
What a great video! I needed to see this. Well explained and good camera close ups.
Except for the background music which drove me nuts. Cannot focus with that noise in background. Please... no music in any DIY videos. Music in any video is takes away from content.
so basically soldering...
***** Ok dude, try using a brass/bronze rod with a propane torch - it doesn't work. Hell, even mapp gas sucks for brazing. Yes, the gas itself burns hot enough to melt the filler rod on it's own, but it will not get the base metal hot enough for a regular brazing rod to flow. Now you can easily braze with either if you add oxygen to it, but on their own you can't do real brazing. This dude in the video wasn't even using a real brazing rod.
connor cadogan I don't know if I'd use a torch to melt osmium. Doesn't osmium produce a toxic gas when introduced to oxygen?
***** Believe me man, I've tried brazing with propane (and mapp). I've sat there holding the propane torch on the base metal for what seemed like10 minutes, and the shit still wouldn't get the brazing rod to flow. Plus holding a flame to the metal for that long causes all sorts of oxidation. There's a reason either air/acetylene or oxy/acetylene are used in every industry where there's brazing involved. Propane has it's uses, mostly in plumbing, even though I don't use it. I always use mapp for plumbing soldering jobs and if I need to braze or bend or heat something up, in that case I grab my little portable oxy/acetylene kit.
connor cadogan Ok I'm not too knowledgeable on working with osmium, thanks for the info
connor cadogan Yeah man check it out, as I said I'm not the best person to ask about working with osmium but I had heard a while ago that it produced toxic fumes when in contact with oxygen. I've soldered, brazed, and welded all sorts of metals but don't think I've ever worked with osmium before.
Never knew this was possible. Copper, silver, brass, steel sure but...never thought this would be possible in an open oxygenated environment and aluminum. Reminds me of my high school jewelry class days of brazing sheet silver rings together and the like. Miss that. Fun times.
i'd rather have braised ribs, personally...

hehehehehe chianti brazed?
You could weld an extra aluminum plate over the first weld to create more strength as well.
without a waelder
Thiago Ikeda spell check.
for a sure bond, such as a rack or shelf to hold weight a spool gun or high frequency tig welder works best. I weld aluminum boats using high frequency ac tig welder made by miller.
And to think I spent $4,000 on a TIG welder.
a TIG will hold many more times more weight than this.
GREG GERHARDT Can you weld aluminium? I hear you can get some mad money that way
brazing is in no way equivalrnt to a good weld
Was it made of silver?
Yeah, no way that welder was worth it. It only allows for strength and versatility....
Brazing, when done correctly, is much stronger than most people realize. Usually in most circumstances, when "testing to destruction" I've seen the metal itself fail instead of the joint. The joint was actual stronger than the base metal it was holding.
This is NOT brazing and is certainly not anything close to welding. Brazing uses BRASS. That's why it's called BRAZING. This is just soldering and is not very strong.
+Don Burd I've read that since I posted this. most of the time brass is used.
I've used copper phosphorus rod to braze large copper pipe joints using an oxyacetylene torch. Soldering refers to any joint made with a tin- lead metal under low heat.
Lead -tin used to be the primary solder metal for years until environmental concerns caused it to be withdrawn.Sorry your not old enough to know this!

@Buck. Soldering and brazing use both fillers that melt at a lower temperature than the metals of the pieces to join.
Soldering is below 450°C using generally but not always a tin alloy, you can see in the video zinc alloy rods that melt at 380-400"C so technically it is soldering.
Brazing is between 450° and the temp of fusion of the piece to braze. Practical temps are between 450-900°C, most around 700°C. Plenty of alloys are used as fillers but the most common are copper alloys.
Been a welder for years and I'm sorry to criticize but: I do give you credit for putting "Weld" in quotation marks in the title but what you are doing is exactly what you call it in the video, brazing. Very similar to soldering. You did stick the aluminum together but I bet you can break it apart easily with your hands. We don't want anybody brazing thinking they're welding and get hurt by the parts breaking.
Like everyone else and their mother has said in the comments, this isn't welding.
Correct. Never said it was. Thanks for playing!
"How to "Weld" Aluminum Without a Welder" is literally the title of your video. The only one playing, is you.
