We use similar rods in hvac to braze aluminum coils and we test to 500 psi and the systems run at 350 to 400 psi in the condenser coil and hold gas! Works great the only issue is the flame of the torch tends to pull the oil film inside the coil to the leak so your prep is super important!
Super good information. Thanks for watching 😎
the trick is do not use iron based wire brushes . This welding rod composition is mainly zinc . zinc and aluminum are in the same covalence ring . they love each other . Use stainless steel or solid brass brush to clean the surface thoroughly . Also ONLY aluminum oxide sandpaper .
G'day Mate. I'm a second generation refrigeration and air conditioning mechanic with over 50 years personal experience. I first saw this rod only about 10 years ago and was so curious that I bought some. I paid $75 US for a Kg. I have successfully used it in repairing aluminium condenser pipes on car A/c systems and also the evaporators. It's a product that works....and is compatible with refrigerants.
Good to know thank you
Hi from the UK
It's good to see that someone who dose weld properly give a positive review of them, they will never replace a proper welded joint on something structural but will have dozens of uses. It's my understanding that they were developed for the air con and refrigeration sector as most industrial units use aluminium heat exchangers and the process is not dissimilar to soldering copper
Keep up the good work
This is solder he used correct??
@@irishguy200007this is more akin to brazeing. I believe a brazed joint is stronger than a soldered one by a good bit. But they are both outclassed by proper welding in ever way
I have had the "Blue Demon" brand in the drawer for about 5 years and has been very handy when needed. I found the rod melts at about 600 degrees and not quite hot enough for best results, so I have used a temp stick since I found this out. Acetone, stainless wire brush then acetone again then flux. I have been very happy for the few times I needed it. Another great video!
What exactly kind of flux you're using?
These rods have flux already in them
Seriously. what brand flux is compatible w/ Aluminum?
@@derrikarenal3308 sorry my blue demon rods don't need flux, my Super Alloy 5 rods came with flux. The Super Alloy 5 are better for radiator and other repairs on older materials.
I filled some 3/8ths holes in a 28 foot pontoon boat and it worked out great
I thank God for UA-cam and videos like this, they are seriously helpful. I have been looking at ways to bond aluminum together without welding for a while and this looks like a seriously good approach. 3M has some adhesives that are really strong and are used in certain applications commercially, but the bonding times are lengthy in comparison to this approach. Thanks for your help and God bless you.
I actually fixed a radiator on the side of the road one time with those rods I had in my truck. A guy broke down and had a leaking radiator. I grabbed the torch and a rod and was actually able to stop the leak or at least until he could get it repaired. They definitely have a time and a place.
Good luck with plastic brackets
@@luislongoria6621 yea seriously
I did an alumiweld video years ago, love the stuff for the right project. Basically aluminum soldering, but its super strong. I first came accross this stuff in the 80s, somebody was doing a demonstration at a flea market sealing a hole in an aluminum can. Larry
Still waiting to see that one. Probably the #1 most used line for welding aluminum
I have a small room/shop in my house that's pretty well organized. It looks a little like a hardware store with a workbench against one wall. I have a specific box labeled "specialty tools" that basically are things rarely if ever used or "just in case stuff". I have a pack of these in that box but hadn't tried them. You've given me a head start, thanks.
I have a couple bundles of those around here somewhere.
I learned that you need to brush aluminum in one direction, if not you push all that oxide back into the base metal.
I've used that type or rods about 30 years ago and they worked great for what they were used for. We would use them for building up damaged lowers on outboard motors. Loved the video on the welding table build. I picked up the same saw for $40 on market place in my area after seeing the video. That table is HEAVY!!! Thanks for the informative videos.
great tip for fixing my damaged outdrive, thanks!
A friend repaired a VW Beetle gearbox to engine mounting lug. It has only four to carry the whole engine so couldn’t possibly work. Could it? It kept going 10,000 miles before he sold the car.
I tried to do a similar job on a motorcycle engine but struggled to get it aligned. Ended getting it TIG welded.
You should never point the torch directly to the rod. That will only melt the rod while the pieces you're joining will not be sufficiently hot to provide a strong bond.
I highly doubt this kid needs any pointers bud lmfwo
Lol
You should shut up
It seemed to work fine to me!😂
@@danahart5322 he obviously does. He can weld but he's not doing this right. Any home plumber knows how to sweat solder which is really what this is
The reason the galvanized hanger broke apart is because of the way you applied it. You could see that you melted the rod with the torch instead of properly heating the base metals! But it is a great video thanks.
Don't think so. 9:01 - 02 he does direct the gas at the solder at the start, however the rest of the shot he's quite a ways away or pointing it further down the weld. It didn't hold most likely because it was galvanized and I don't think it actually got the metal hot enough as witnessed by it melting like cheese vs flowing. I think the manf. was honest that it WOULD allow you to solder galvanized, however nowhere did it say it would be as good as removing the galv beforehand...
It did way better than I thought, was questioning saturation but it works.
I made some charge pipes for a turbo car I have. It failed the water test. Small seepage. I did band of jb weld to all the seams. They have been solid for over a year. 14psi
Hell yeah
Great idea with the JB weld!
I'm about to do the same but with a MAP/Temp sensor mount to an aluminum intercooler tube.
@@damianmcgriff2665lol yep I tried that same exact thing but mine ended up being super ugly and leaked so I ended up just buying an adapter/fitting for my specific sensor that threads into itself through a hole you drill in the intercooler pipe and thanks to gaskets inside the fitting it seals right up! I even pressure tested it to 90psi with my air compressor multiple times searching for boost leaks and no leaks whatsoever!
I used this stuff to build up a boss on an aluminum water outlet that was too thin for the sender and its 1/8npt threads. I added a little under 1/4" of material and it drilled and tapped nice and worked for years without a problem.
You knew what it was all about and it’s good to get the terminology established. MIG, TIG, MMAW , SAW Brazing silver bronze or good old soft solder. Thing is know what you are doing, terminology is important but knowing the limits of all these processes is very important. Thanks for the vid
Great vid, great approach, open minded not only to welding but to except that other methods are also available around.
I am soldering for 28+ years now, learning to weld for 3, enjoy both worlds ... :)
Thank you. I just made an aluminum oiling drip can for my drill press with these rods! Works perfectly with no leaks! Flexible oil coolant line from Amazon and my new oil container for the win!
I had my doubts about those aluminum welding rods, but after seeing you use them, I'd definitely try it for light duty aluminum bonding. Thank you.
Aluminum welding/ brazing rods are great if you have a decent temp control welder or torch. In my experiences they act as a great indicator for area heat cause the worst part of Aluminum is the ease with which burn through occurs
I need to repair my toolbox, I'm curious how well this will hold
@amcustomfab
@MrAtaripitbull Why only light duty? Why no structural applications?
Can I use it to fill a small whole on a transmission on a Dodge Journey
i did buy some of them to use in filling gutter scratches on my mag wheels !
This stuff actually works amazing on case holes in atv and motorcycle engines. I've been using duraweld and alumaweld for years and they work great. Like you said, there is definitely a proper place and time for this type of stuff VS actual welding, but it definitely does a good job if used properly and on the right applications
what I have done for galv steel to aluminum plate is affix a very thin layer of the alum braze to both sides of where you want the weld. Then clamp them together and do same as you did in your video, weld a bead
Larger surface of contact, you won't be able to pry them apart with your screwdriver like you did.
Interesting did you tig braze it or just wet it in with the torch? I might have to try that
39,000 psi tensile strength probably refers to material in the solder/braze deposit, not the solder/braze joint itself. Given the area of the joint, it could still be quite strong. Someone else mentioned carefully cleaning the end of the tube, that is very important for a water or air proof joint. That is particularly important when both sides of the joint are not solder/brazed.
Haha way back in my misspent youth, I used something like this to solder old lawn chair tubing salvaged from the dump and cut-off aluminum siding pieces to make mufflers for model airplanes. Worked great even after joints were filed smooth.. Never had one fail We didn't have many $$$. Each muffler cost a few cents. Commercial versions were $30.
MAny thanks for the demonstration. I had planned to test the feasibility of soldering aluminium framing for an internal ute (pickup) canopy. You've answered my questions, yes it will hold up for the intended application. Cheers from OZ
Thanks for doing this experiment - I will give this a try on some alu box section, I want to build a mono wheel bicycle trailer to haul camping gear and a solar panel but I can't do welding. I will even see if a 'blow torch lighter' will get the joint hot enough so that I could do repairs out on the road if need be.
Looked good to me especially for light duty applications. Thanks!
don't forget you can try bronze brazing rods. ( takes a lot more heat btw).
Show us your video where you do this. I am super intrigued what with the melting point of bronze.
@@chrisallen2005 I haven't necessarily made a video about it but I could whenever I get the time. The melting point is 1800 degrees I think. So you need a super hot torch or use acetylene torch like I got but you got to turn your temperature way way way way way way way down
Another very good video about this topic is the one from Project Farm entitled:
*Best "No Welder" Aluminum Welding Rods? Alumiweld vs Bernzomatic vs Hobart*
That's actually surprisingly strong
I worked building A/C fittings using oxy acetaline torch . One tip i leard to teach others is . Clean and brush and use brake cleaner to remove any oil residue . Light torch without ox and apply it yo metal . It will leave a black suit color . Now adjust to soft bue color and start heating the metal slowly the black will dissappear idicating the part is hot enough . Next apply the rod and it will run in . Dont stay on the same place to long or you will melt the part . Let cool brush clean . We used a thin rod called AFC 1000 .
Definitely, has a purpose and I'm sure there are many useful real aplications.
nice this will make a nice easy project to fabricate my step van licence plate holder thank you, Cara
Good video. I am searching for tutorials on how to weld a broken piece of aluminum alloy bike tube. 7001 aluminum. Many said it wont be strong after heated. Well, after seeing your vid, i think i try that.
Hello this was a great useful video, with my lack of experience, I didn’t not know it was possible to weld aluminium so easily like this and not melt the aluminium itself thanks
That was surprisingly high strength. Didn't think it would hold up that well.
I love it when you work with Aluminum!
Hooray! Congratulations on a good build of a good idea! I have been frustrated in the past and had given up this channel because it seemed like rush and haphazard work made good ideas fall short. This one did not disappoint. Good workmanship despite using period blacksmithing and other techniques. Congratulations on a real success and I hope you do find a good stream for testing.
This is awesome to know im going to be custom making a aluminum heat shield for my harleys exhaust
Bahan dari aluminium.salam dari pandawa aluminium🇮🇩🇮🇩
Thanks for the content. I have had some rods for years never tried to use them. My friend has a boat that needs a small tear repaired. I think I will give it a try. Thanks
I repaired multiple holes on a Jon boat that have held up for years with these. Practice on scrap first.
Having done welding on school , im surprised it sticks well well done
Holy crap... That worked pretty well for its intended purpose.
The average joe needs to have an alternative to the intimidation and higher entry level of welding and that fits the bill.
Most people would run to the hardware store and grab a pack of JB, this is an accessible entry point for projects that JB weld would be fine with.
Well I still wouldn't use this for anything structural. But it could be a good alternative for light duty stuff
@@amcustomfab Totally. I also wouldn't trust anything structural to hold using epoxy.
Nice alternative to "gluing" metal together, and faster.
0:52 "definition of brazing is anything above 840 degrees"
Maybe you're right. I don't know, but I think the difference between soldering and welding is that when soldering, the pieces to be joined do not themselves experience melting at all, while when welding, the pieces to be joined melt from the joining point into a solid piece. When soldering, the pieces to be connected stick to the metered medium, which is the same as gluing.
Try working the rob from the inside diameter, while heating on outside. when working sealed fittings. Ensures flow all the way through the joint.
Flux makes this a whole lot easier. Also, clean clean clean. I have had my rods for 10 plus years and only use them for minor repairs. Honestly an inexpensive AC Tig or Spool Gun Mig is easier to setup and use then dragging these rods out and doing a bunch of prep work.
For once or twice a year use, the $15 torch and some plumbing solder beats a $100-200 Tig. 2-3 min with some sandpaper and acetone/brake cleaner isn't exactly a time sink.
I have a little experience in soldering copper and silver. I was definitely thinking flux and getting the temperature right. For silver I used borax ,for copper standard plumbing flux. Looks pretty strong. I wonder how it would handle boost and also vibration
I used vixal toilet cleaning (HCL-17%) + PCB (Normal Solder). Work with iron soldering its work and save money
Look up, calvinic. Action between aluminum and zinc or galvanized metal, it's not a good idea.
Nice.. this is going to be great for big 1/6th scale rc rock crawler project --- i had a dream aluminium should be able to be soldered together somehow, i mean why not. youtube and voila --- thaniks for the lessoning!!! You made it look really easy and i'm sure its not -- I do have a couple cans left of MAPP gas but i conserve it like crazy cuz i heard they discouniued selling it --- prolly need tha textra heat to make it solder well. Think of it like this --- Welding -- you are actualy melting ALL THREE PIECES of metal being joined together -- as you said into a cohesive single piece of metal. soldering you are heating and melting a metal and sticking it to two other metal surfaces that remain in tact during the process -- never melting, just getting melted metal stuck to them under high heat circumstances. It should work great in small projects like building trusses for axles in r/c. Cant wait to try!!!
Pretty impressive. I bought some a while back but haven’t tried it yet. Will have to keep it in mind. Thanks for the video!
I know a lot of people think temperature is the key defining factor if something is brazing or soldering and while it's a part of it. It's only one piece of the puzzle. The real difference is the strength of the capillary action at work. Brazing rod material allows a capillary action to flow into significantly tighter spaces allowing for tighter fits of parts. What determines this is the material the rod is made of and thus the temperature it melts. To sum it up technically, temperature has nothing to do with brazing or soldering but rather a byproduct of the defining factor.
I also wouldn't recommend thus for rim repair. Rims are selectively cooled to allow the hardness of the alloy to be harder in some spots and softer in others. You might aneal a spot that was meant to be hardened or harden a spot that was meant to be softer. Please, just buy a new rim if someone out there is considering using this to repair a rim.
Good demo, i was a bit skeptical but it has application. "Go build something" :) just for that i am following your channel.
this is great to make a small carb intake manifold for my bike sweet.
Great video but for everybody, commenting about using flux what type of flux do you use
Have you soldered copper pipe for plumbing. This looks identical. Flux helps. clean and rough both parts, dab a little flux on, connect the parts, then apply the solder (called "sweating"). If the copper is the right temperature, it will suck up the solder into the joint. If not, it makes globs like when you tried to weld/solder the galvanized hanger to the aluminum plate.
Its called brazing. Banned in UK bodywork repairs for years. Every year cars over 3 years old have to pass a M.O.T. test ( construction and safety test ) before it can be used on the road. The car will fail the test if the examiner finds brazing.
Some countries are a lot less strict on car repairs.
Everything is banned in commie UK.
I've been planning on creating an intake barrier to prevent heat soak on my 1.8T VW Passat. Having the exhaust manifold and engine block to the right side of the intake filter, something needs to be between them much like on the OEM intake box. Was a bit worried about using my flux core as that's a bit overkill for the application risking burn-through.
Great,objective video. Came to your site by accident but glad I did.
Thanks for subscribing 😎
I didn’t know this existed, but have some aluminum parts in the shop that need to be welded. I will remember this for some other applications however.
Outstanding, I like your presentation, thanks, blessed.
Thanks for the support 🙏
Brilliant video! Really helpful, thanks.
Aluminium was discovered by Danish scientist Ørsted in 1825 and used first time in a production by a french entrepreneur. It's spelled ALUMINIUM, because that's what Ørsted called it...
If You take off the oxide layer at the bottom end of the tube, it will seal with no water leak.
I've used this stuff many times, on scratched engine covers for classic bikes. Works like a dream!
Mate can this be used to well a aluminum bearing cap?
I tried something like that and I couldn't get it to work properly. I probably didn't heat the job area properly. I think I was hitting the rod with the fire, so it didn't work. I didn't know what I was doing. LOL
But when I needed to repair an aluminum radiator, it worked great.
I think the reason the two different metals stuck because you did go through that hole, so the aluminum solder held by that section.
I've definitely found it does not work as well on thicker materials tighter to get the piece up to temperature and hold the heat while you try to solder
I think for wheels, would be great for filling scratches and dings.
It just occurred to me that I may have seen a solution to the "breaking the oxide" issue that you mentioned. On a number of the other videos that I've seen on this process, the procedure was to scratch through the puddle while it was molten and into the base metal with a small sharpened stainless steel rod. I don't know if it impacts what you where speaking to, but it, somehow, it's supposed to make the solder bond better to the base metal. Just thought I'd throw that out there, since I saw it.
Welding electricity is use to produce heat at a point just using gas takes a longer time to reach its why you learn amperage heat and current flow wire speed if the heat isn't equal then the weld is not effective cooling down metals and fillers at the frequencies hope it helps a wider view at Welding for you
After heating the aluminum, it's now "annealed aluminum" and very soft, thus beating it will bend very easily. Try heat dipping it after soldering it. Make it hard again.
This would be a good experiment to do. Thanks, For the idea
Those torches are great but it would be good if they had a n attachment for fine work.
The rods are pretty good used them for years.
Great information - thank you. And those are great looking beads.
Another good review Alex. I just ordered some of this. Ive gotten so many good tips from you. Please keep t video's coming. Take care. JT
Thanks for the support 😎🙏👊
THANK YOU I NEEDED THIS PRODUCT
That stuff looks like it would work on sprint car wings and some modified and late model bodies
Repaired multiple holes in a Jon Boat with these. Has held up for years. Easy cheesy.
I watched a guy at the fair selling this type of rod when they were a new thing. His 'welds' looked perfect. He hammered on them. The aluminum bent to the point of destruction without letting go. I purchased some, I had terrible results. I think maybe I needed some kind of instruction. Or the rods he was selling were different from those he was using.
I tried a tig welder it worked but it wasn't as easy and didn't look as good as steel. The owner of the tig welder could make perfect welds.
Thanks for sharing!
Kind of Dicey Soldering Galvanised materials, if you get too hot Galvanised materials give off Toxic Fumes. This is pretty low temp so it's likely ok but most "Do it your selfers" are not that knowledgeable and if using Map Gas could overheat the Galvanised material.
I got some of these their not expensive but haven't got around to having a go with them mite try them see if its easy as it looks
Thank you I've been wondering about that stuff
You can remove the oxide layer with oven cleaner.
Very informative.Thanks!
one thing i'm curious about is the alloy, since some metals are cancerous to others
This has been around for a long time 80 plus years
The reason the galvanise and alloy separated because all the heat went in to the bench you didn’t raise the job
Link?! I may decide to do this, because I need to reconnect an aluminum pole. Not only would this pole be supported by this "connection", it would also be supported by the house, with a shelf,and in other ways, as well.
Delaminates by itself at about -40 c (-40 f)
Interesting!
Have you ever done a video on pulse and double pulse mig welding especially on aluminum?
Unfortunately I don't have a machine that wiy pulse mig aluminum yet... 🤞😎One day thanks for watching.👊
The cheap lamp posts sold in Lowes and Home Depot is the same stuff as cast poles.
Not sure why you say you wouldn't use it for structural applications. You proved that the tube failed structurally while the joint didn't, so structurally the joint is as strong as it makes any sense to be. AWS says that brazing is as strong as welding and I think you showed that they were right.
Do you think it would be strong enough for a light use bicycle frame?
Was spinning my thinker about You quest to do something Unique for the left over inneards of the saw. ... Why not leave it as is for the most part except as needed, using the tilt an up down down function of the saw so you can make and add accessories, jigs and fixtures so You can have/make compound angles of any combination in three dimensional set ups.... You can use the arbor as a pivot point for an attached adjustable (setable and lockable) fixtures/jigs. ... There, ... Now You X-Y- ... And a .... Z ... + ... (Considering you can hang things over the edge of the saw ... (pardon me ... "Welding table") also.).
So now you can make and hold your parts at any assortment of precision angles to make something, ... or correct something to fit just right .... whenever something needs to be something other than 90° or 45° on a flat two dimensional surface. ..... There You have it,. A different paradigm, or thought on a direction to go.
It will be interesting to see how far you can use your own imagination with this, might want a separate tablet or stand/station to attach the innards to. ...... Welder, grinder, sander all in on station??? .... Mmmm.
I don’t think you know what delaminate means but good demo on the soldering
The rods are made of Zinc Zinc melts at 6:50 to 700 You can buy them cheaper at Harbor freight Any ox acetylene or OXY propane Will work
Do you think if I used those rods to weld the outside of a 90 degree joint, would I be able to sand it before painting it?
I'm gonna try it on my fan belt! 😅
Do you think these rods would do a die cast alloy like a motorcycle frame, a bracket at the front steering column has broke ,im a bit worried of heating the headstock up too much and paggering the bearing sections ,tho its snapped off in the middle of the headstock , ? thanks for showing us .Ant from Wales UK .
I definitely wouldn't do anything structural with them personally
Oxy Acetylene with a gas welding tip might be a good idea. perhaps a tig torch with a brazing rod & argon would solve the Oxide issue.
