I do some silver soldering in my gunsmithing and I've found that if you place your pieces on a brick rather than an iron vise, the pieces will heat up more evenly, as the vise will draw away the heat.
That's true!
Another suggestion is to try a rose bud torch.
@Brayan Carmona I just said brick, but what I have is Fire Brick. Never had a problem with that. I've done some cutting with a torch and have concrete explode. Not good to be around. Thanks.
@Brayan Carmona My propane torch melts platinum, obviously yours is junk. I can rub my hands together to get 450 degrees or did you forget the 2 in front of that to make 2450 which is what propane gets to? And you obiously have never had a rock explode and fill you with shrapnel, no not all rocks are the same. Volcanic rocks take heat but no concrete type rocks because they still have lots of water inside. If you want your parts hot, then you place them in a sand bath. In fact you can solder up entire boards with SMD components by simply using a solder paste mask so that the flux is only where you want your solder to be and then set thing on hot sand and all of it gets soldered at once.
Would a chunk of solid steel work for holding the heat as well if you wanted it to dissipate faster than steel but hold the heat to a localized area? Maybe even preheat the steel before laying the aluminium on top?
That has been around for over 40 years, we used it for leak repairs on Carrier a/c condsening units that where manufactured with aluminum refrigerant coils.
Very much appreciated. It seems everyone is oriented to the most modern. Torch welding and braising has more potential than we know and I'm learning all I can for practical usage. You taught me a lot today and Thank You.
Never seen anything by you before man but the clean cut straight to the point way you made this vid was beyond great. The exact info anyone with common sense wanted and the exact info anyone with material science kinda mind wanted. Appreciate ya very informative
Thanks brother! I'm inspired but years of watching 20min. Videos that could have been done in 5 lol. I'm sure you know my pain! Thanks for watching 🤘
I remember seeing infomercials for Alumaloy when I was a kid. Just seeing the name took be back instantly. Thanks for that.
Nice stuff! I'm a professional TIG- Welder for over 35 years and I' ve seen a lot of crabb for brazing and welding aluminum. But this stuff seems to be a hit! A suggestion from my side: put the thicker material in a oven, hot as it can. If I had to close the hole in the tank, i would put the small aluminum plate into the oven. So you can warm up the tank with the torch! Best regards from the very north of Germany!!
Thank you! Great suggestion!
FYI - The technique where you pre-braze the edge of a joint before you make the connection is called "tinning the joint". That technique is used a lot in architectural sheet metal work solder joints in copper sheet, galvanized sheet steel and stainless steel sheet metal. Great video!
5 years ago I used the Blue Demon aluminum brazing rod to make 3 small pieces of aluminum angle bar. Used it to secure the latch on two cedar garage doors (barn red) that I built for my garage. My wife was so proud of me. And I enjoyed your video. Thanks again. 🙏🏾🙏🏾
This stuff is amazing for radiator repairs. You can also buy flux (comes in a plastic bucket) for the rods. You just dip the rod in it after you cleaned it of and go to town. Really helps keeping your “welds” cleaner.
One good rule of thumb is to apply the heat quickly. Use as much heat as you can and place the filler in quickly.
More heat over a shorter period of time is more controllable than too little heat over a longer time.
Jeremy Hall. Good point but there is one big consideration. The no warning characteristic and low melting point of aluminum. Many don’t realize it goes from solid to goo suddenly with no warning. Most propane turbo torches can easily slag plate Al so they can still get a nasty surprise. This stuff though not technically as strong at least gives a lot of latitude to guys who don’t do these things frequently.
Thanks for this video! I've seen ads for this stuff, but I wasn't confident that it worked well until I saw something unbiased like this. Big help.
No prob! Happy to help!
I've been using these for 40 years and they work great! I've made some nice looking radiator shrouds.
Do you think these rods would hold on an rv water heater that is leaking at the seam?
@@brandonpierce1729 Depending on how close it is to the heating element... If it is cleaned thoroughly, I would trust them. The water itself is not going to get hot enough to do anything. It is more of a solider than a weld, but don't do it if it can cause any additional damage.
@RichardAC59 it's a propane heated tank so no element to deal with and it's in the back middle of this little 6 gallon tank. I have an acetylene torch to localize the heat and that's gonna get a lot hotter than my blue bottle of propane for sure...I guess the real issue is that happy point of hot enough to braise but not too hot to distort or melt the tank huh. Was just trying to determine if this "might" work over tanking it to a weld shop
Great video Nate , I learned something today from you . I will give it a try for sure . Thank you for posting this. Until next time take care .
I bought some stuff called 'Super Alloy 5' from Muggyweld that uses a flux and oxyacetylene to braze aluminum instead of just soldering it. Although it's nowhere near as pretty as TIG, they claim it's just as strong - 30,000 psi. What I know is, it is tough as nails when finished - especially handy in places it can be cleaned up with a grinder. Used it to patch up my old duck boat hull after a few rivets were forcefully beaten loose and starting to leak. Touch up with a grinder and it doesn't look half bad.
Maybe it's 30K psi as a material, the problem is that it's a surface bond, it doesn't penetrate and chemically bond the way a weld does so ultimately the strength depends on how tenaciously it decides to "stick"- I found an unacceptably high level of variability with that. It also has a slightly different color so you can't finish it out cosmetically like an aluminum weld- although in most cases that doesn't matter.
I used this stuff to fill and seal a crack on a hmmwv 6.2l aluminum coolant crossover tube a few years ago. It's been holding very well with no leaks. I didn't even have to remove it from the engine. It's very easy to use this stuff.
One of those questions that keeps me awake at night has finally been answered, thanks Nate!!
Lol no problem!
Agreed @Kill3rGreen Bear, have always wondered if this would work, thanks @Dirt Lifestyle
I've used this stuff too and i fond out that you can get it to stick better when you use a stainles scatching tool and scratch through the weld.. I was told that that is better because there is a oxidation layer on the aluminum and when you scratch through that the bonding is much better.... I even repaired an engineblock from a ZX7R('93) with it, and that is allready 7 years ago…… Awesome stuff!!
I was thinking the same thing about scratching the surface but for something for the aluminum rod to hold onto.
eaglebrink 93 ZX7R? Sweet bike bro.
Im glad you shared this, ive been messing around with brazing in the shop lately to. Im told they make a paste or a flux to help the braze bond a little better when messing with aluminum, I have not tried using it yet... May makes things go a little easier!! thanks!!
The first video of this rod I found, they filled a hole in a coke can to show that the heat needed does not come close to melting the aluminum. Thanks for a great video.
Oh really? That's cool. That's what I was worried about. Off to amazon...
In the 60's I used 'Aluminum' solder. It was in a spool like lead solder but much thicker/stiffer but it actually had acid flux in the center similar to plumber's solder. Worked okay, for aluminum.
I hardly use these rods but must agree they're well worth having in the workshop. Recently used them to patch up a badly corroded ally boat part which would have been impossible to tig weld due to salt contamination, because the base metal isn't being melted which releases locked in contaminants (as in tig) this was the right choice.
I have used them, I was surprised how well hey worked
Great video, thanks. After bending up some 0.060" aluminum for my homemade car fan shroud, I used this aluminum brazing rod to seal the corners of the panels. Worked well. You're right about getting everything as clean as you can!
Awesome man!
I use map gas torches all the time I love them. I have a few of them but I got the ones with a hose and the tank clips to your belt. Its all I use anymore. I used to lug around a big acetylene torch but I actually got scrapped it years ago for the map torch. It doesn't get as hot but it gets hot enough to compensate for the weight in my book
That is super awesome! I can’t wait to try it. As always Nate...great video! ❤️🐞
Ultra cool and ULTRA cheap. Two of my favourite things.
Thanks Nate. Awesome as always. 🤙
Thank you for watching! How inexpensive these rods are is very attractive
Thanks for this video! That’s why I love this channel... I learn something every episode!
Thanks for this. Have been curious about this stuff for projects since I first saw it. Great video, useful tips!
This is a really clear demonstration of how to prepare your pieces prior to brazing, and how to spread heat to form a more secure joint.
The original brazed joint would have been sufficient for the application, but it was good that you showed how to make it even better.
These rods are invaluable and to spend time practicing the techniques necessary to gain the greater spread and bond strength will be time well spent.
Thank you!
This rod works great to fix cast aluminum parts and even pot metal cast parts. Using fire blankets to keep the heat in works good, just wrap all the large areas with the fire blanket to insulate the piece and keep the heat from escaping.
Insulating fleece/rockwool and thick aluminium foil are your friend. Just create a fleece/foil sandwich and "mould" it around the workpiece. Works like a charm for small parts, awkward spaces etc. where you can't get a blanket in 👍🏼
Stick the base plate on a ceramic hob to get it up to temp. Don't use a gas camping stove like an idiot mate did. Unless you want a mini diorama of a certain famous Terminator scene that is 🤣🤦♂️
Agreed with the brick, alternatively a ceramic tile.
Oh My Gosh! This is awesome. I already have the tools, so now I can build an aluminum box to mount on my motorcycle. THANK YOU!
No problem! I'm glad the video helped your project 👍
I used to use an alum. rod back in the 70's.... from Forney Welding, Ft. Collins, CO. They would advertise that you could patch a hole in a coke can! It came in handy on an amazing number of projects
yes I have seen them weld a hole in the bottom of a coke can at a sales demonstration at a g*n show years ago
Wait until your better half goes shopping and use the oven to pre-heat your parts. Thank me later 😂
Every metal shop should have a kitchen oven. Find them behind appliance shop. Dishwashers are handy as well.
@@gregwarner3753 too right
Gas grill works too...
@@gregwarner3753 What kind of temperature can you get inside a dishwasher on the "dry cycle?"
Considering plastic does not melt probably less than 220 dag f.
A nice little tutorial. Thanks.. I have an electric aluminum e bike, and this stuff may come in very handy for sometime in the future.
Amazon alternative to aluminum brazing.
Good job, cool video. I've been tig welding for many years, but til this day, I'm still learning.
Thanks man! Tig welding is a much stronger process then this product but in times when I don't feel like firing up the tig welder I genuinely think this can work on the right project 👍
These rods have been around for decades, as we see booths at the annual farm/ag shows. Farmers typically have welders, but not always for doing aluminum, so this provides a decent alternative for them without the high cost of a good quality MIG or TIG welder.
Good information. I’ve seen it but thought it might be a gimmick, now I know. Thanks Nate! Can’t wait to see the bump stop video 😃
Thanks man! I'm working on the bump stops all weekend 👍
@@DirtLifestyle ua-cam.com/video/n1njyuPBIH0/v-deo.html
This has been around for years! Used it 10 years ago. Nothing beats my tig welder.
Yeah im going to have to have some of that in my truck, don't know how I missed it. Thanks
Small tip: when your using the rod to test the temp at the very beginning of the “weld”, once you get the melt you want, flip the rod around and use the cold end to start. Of course the rod heats as you move along but it will make a cleaner beginning to the bead. Something to do with the thermal shock. It also helps if you flip to the cold end if you are just trying to dab a tiny spot.
I knew someone who used "Lumiweld" (similar product) to repair a VW Beetle gearbox/engine mounting lug. "That's never going to work" but he had nothing to lose. He needed LOTS of heat but ran the 'box for 1000s of miles with no problems. Big items need A LOT of heat and the rough surface of crack faces have to be filed smooth.
YOU MUST use a stainless wire brush and stainless scraper wire. Carbon steel will spoil the job.
I agree whole heartedly and mark all your stainless steel used for aluminum "aluminum" so you don't mix it's use up with the steel projects.
discovered this stuff a few years ago and used it to repair my honda engine casing. I'm currently using this to fabricate an alu battery box for my BMW K100 that I'm chopping
This is fantastic. I learned something really useful from this episode. Thanks!
Its funny how we used to use a propane tourch and wire hangers to braze anything from body panels to gas tanks. That was back in the 70s.
😂 😂 😂 That was our go to welding repair methods "coat hanger" on our farm! I can say with confidence 30+ years later many pieces of whatever is still holding strong!
I heard the wire hangars of yesterday were a lot more helpful. Accountants were so sure to have companies make cheaper ones going forward.
For fixing leaking radiators, I reckon that is perfect 👍
Saw a similar product in the 90s at an agricultural show. The bloke seling this welded a coke can and the weld was stronger than the rest. Everything crushed yet the weld was intact! Amazing stuff! Haven't seen it since only on UA-cam! Nice job! 😊cheers from Australia!
Thanks man! Your living the dream over there! I tell my wife I want to move to Australia all the time!
Thicker material is easy compared to thin....I used to have to do evaporators on older fridges, from people doing the ice pick defrost and puncturing the coil inside the freezer....Could be a real headache, especially depending on where they did the damage....Self defrosting refrigerators....What a blessing....This still taught me how to connect aluminum pieces...Thanks for that.
That sounds like a pretty interesting gig! Thanks for watching👍
Aluminium has an oxide layer. These brazing rods will go through it to alloy with the aluminium, but you will get much better results if you remove the oxide layer and tin the surfaces to be joined first. This can be done in one step. Heat the part to be tinned and once hot enough, melt the rod onto the surface. Use the stainless wire brush to rub the melted rod in / remove the oxide layer. You might need more heat or rod to get it nicely tinned. When the oxide is removed you will see this stuff flowing and sticking like crazy to everywhere the oxide is removed which is hot enough. I think the rods are usually zinc alloy.
I've done a fair amount of aluminum 'brazing' using a torch and rod. One very useful tool that i made, was a stainless steel 'screwdriver', with a wood handle, that allows me to scrape the base metal under the filler to meld the two together. Scraping removes the oxide layers, and also allows me to 'flow' the weld joint. The result is an extremely strong weld.
BTW - new users should note that the rod does NOT flow or wick like solder or brazing, and I found that advertised fluxes are not really necessary.
I agree I like it too. Im building out the back of my 4runner using this style method
Way to go bro. I was actually thinking about trying this on a couple projects. Thanks for the video. Have a good evening.
Thank you!
Would have liked to have seen the pressure test 👌
I saw a demo of this brazing rod in the late 1970s. Learned a neat trick. If you use an oxy/acetylene torch, you can run it very rich on fuel and coat the aluminum with soot. Then add the oxy 'till you have a slightly carbonizing flame. As you heat the parts they will be exactly the right temperature to braze when the soot burns off. Then work fast.
Better use wood, you have woodsoot and the right temrature to brace, lots off soot are not good the area to brace need tho be clean
Seriously killer cheap hack! I have actually never welded but I used to build vacuum tube based amps and apart from soldering for years, I used to work with aluminum a lot. This seems like a good way to step up a bit into welding (I own a welder but haven't tried it out yet). I own everything shown in the video except the braising rods. I could use this on a lot of things even outside of Jeeps.
Excellent info here.. I like the idea of brazing stuff (it is actually a better bond than most may think)
its tough depending on size and shape of project, but pre heating parts in an oven makes all the difference in bringing larger part up to temp for brazing.
I used to do brazing in high end bicycle factories. Mostly steel/chromo with brass and nickle/silver. For one run we had to braze an aluminum water bottle boss onto a chunky aero down tube. That was hard to not melt that tiny threaded insert. It was all about general heat (a lot of it) and the right flux, and then timing. That filler rod must have some kind of flux built in.
good idea. I have used aluminum soldering kits a number of times. You do need to clean the aluminum surface, use the flux suggested. AND there is always the danger of going too hot and melting the aluminum pieces! But it does work and is fairly strong.
You made it easy for me that I'm trying to start something. Thanks
I ‘welded’ all of my aluminum intercooler tubing together with the Alumiweld rods sold at Harbor Freight. Was tricky to control the heat, but got the job done. Pressure tested to 40psi.
Exactly was I was looking to hear. Going to do the same - experiment with alumiweld on intercooler piping on latest project. 40psi? More than I need.....sweet.
Good to see this response, I was thinking about using it to "weld" my IAT bung and BOV flange. thanks!
So glad to see this. I've got a new radiator that's sprung a leak if it will hold 40lbs of boost it shouldn't have a problem holding 16lbs
Yeah just be easy with the heat fellas as alloy crumbles easily if you're to harsh with it so go slow... Use some test pieces if you have any and practice first as it really does take little effort!
Evilstorm11 Wow what’s up your ass? I fabbed my charge tubes up back in 2012 and haven’t had a single issue. The engines a Duramax LBZ putting out 26 PSI of boost, and taking me over many miles of off-road terrain. Clearly you don’t know what you’re talking about.
I its same product I had a like product in the early 80's I fixed my lawn mower housing with ...... MAPP torch and those rods . A good repair.
Early 90’s it was an hour long informercial. Or they have just updated the infomercial and they added it to UA-cam.
Thanks alot man. Ive been looking for a way to bind aluminum.
I've used these rods a few times, they work well and are very convenient.
Very cool man, I been using those rods from harbor freight for my rc models to make mufflers to scale they work good after you practice a little
In the hvac industry we repair aluminum the same way and out welds hold 500psi on condenser coils
scooter with aluminum rods, the 15% won’t stick to the aluminum
@scooter The Industry in General of Manufacturing and Fabrication is in a low quality state Because everything, Tools and materials are from China. I'm amazed at what cheap sellouts
are people in all western countries letting this to happen. Boycott All kind of Chinese crap! People need to force their politicians, to make this industries "made in your nation". There's a lot of benefits even if prices go up. Cheers from Houston,TX.
Thoughts on using this on an rv water heater that is leaking at the seam? Aluminum tank obviously...
Thanks for reminding me! I used this stuff at least 10 years ago in my Motorcycle shop in NZ. Brazed a lump of old alloy over a hole in the crankcase after a farmer threw his bike down a gorge - piece of cake with Oxy/acetylene.
That's pretty cool. I seen that aluminum rods before in a Comercial but didn't give it a thought. Definitely going to pick some up. Thank you.
From a professional welder to another yes it has its applications.
I've used such rods to fix a crack on my aluminum oil pan on my engine few months ago and it is holding up very well. But the material has to be very hot and stay hot for a good amount of time to get the alloy form and diffund into the aluminum. 400 deg. celsius was needed, it is kind of hard to maintain with a torch on high surface area/mass.
I always feel like I'm stumped when it comes to minor welding repairs/fabrications as I don't have a decent welder... This video helps a lot and i got a bunch of applications for this technique already --Thanks!!
Great to hear! Give it some practice! Good luck!
Keep up the good work. You are a natural teacher.
Thanks man! I appreciate it 👍
Last time I welded aluminum was also the first time. The project was a one of a kind Transit Rail Simulator, (testing the forces on autos on train cars), With 2500 feet of it, by the end of the first day 12 hour day, I was pretty good. At the end of the 4th day I was more then happy to retire. But thanks for the memories just the same.
Thanks, this was useful to see, I have some rods and a mapgas bottle but have only done a few test pieces so far.
Wow this is a game changer for me and garage time with my son.
Thank you!
✌🏽
Awesome video the more you upload and build the more your channel is growing I also spy a new jeep👀
Michael that’s his brothers rig
This stuff looks like it is perfect for building fuel tanks, coolant tanks, etc :) I don't have the proper welder (or the skill to use it) to weld aluminum, but I do already have a MAP gas torch and a stainless steel brush. I will have to give this a try :)
Got a dual battery tray to build and I really didn't want to use screws. This is much cleaner and professional looking. Only have a stick welder and my skill with it is not up to welding aluminum just yet. Thanks for the great tip.
speaking as a weldor , when welding 2 metals of differing thickness u need to spend time pre heating the thicker metal then lay your patch down and solder immediately . thanks u made up my mind to try this stuff out .
I have been wanting to try them with my tig on real thin stuff . I bought mine from Harborfreight .
Another awesome vid! I've been curious about this too! I saw a guy filling a hole in a motorcycle gas tank with just the rod (running in a circle on the edges, making the hole smaller until it was filled) I really wanted to ask what kind of magic he was using, but he was on the clock...
Amazing. Looks good stuff. I’ve got to get some of this Love it. Cheers mate. Larry Sullivan in London I love you videos you explain things so good thanks keep. This motor running
Thanks for showing this to us!
You can also get this at any harbor freight in the welding.rod area, ive used it several times on smaller parts on my rc planes
I cant never get the harbor freight ones to work right.
@@JM-yx1lm Hmmm, their welding wire isn't a problem for me in MIG, but I haven't worked in aluminum.
Pretty neat. Would be a cool way to make some interior panels like a dash or glovebox
Thats a great idea
Man I really appreciate your videos, really helpful stuff that I see myself incorporating in my van build
Thank you! Happy to help!
1.2 MILLION VIEWS!! Good for you buddy!! That's awesome!!!
On the subject of "safe practices", it might be a good idea to move that acetone a little farther away from the heat. I'm sure it mostly evaporated, but you wouldn't want the rag to catch fire when you're not watching, heat the can, and go boom.
My neighbors act like I'm the Wylie Coyote of DIY, but I saw that acetone and thought "hell no!" Good to know it wasn't just me.
i remember using this stuff back in the late 80s/early 90s - braising aluminium has been around since WWII
Probably much longer than that
Awesome video thanks a lot very informative and exactly what I wanted to know and was curious about
I’ve never used it myself.
But my buddy used repair his aluminum tool box.
Seems to be pretty awesome.
I feel like an idiot.
I forgot the word “it” in my comment.
Oops
I’m an Aussie so I’m waiting the whole video for this stuff to glow in the dark lol.
Adding flux makes a big difference , I came across Aluminum brazing in the 80s .
Thank you for sharing this and showing us
Great idea
I have seen guys fix alloy rims with this type of rods looks realy good.
Awesome video! I guess I will have to finally try mine😅. Just a heads up Nate, once aluminum is welded unless heat treated again it's still only a 30-50 psi, joint around the heat effected areas. Depending on the alloy. So in the grand scheme of things it's really not much if any weaker. Also beveling the edges gives it more surface area, meaning a stronger joint. Also this process can anneal any heat treatment.
Thank you! Good to know!
Would the method in this video be able to handle the pressure of a motorcycle radiator?
@@stephenhacsi9623 yes
This rod has been around for 25 plus years, a buddy put a nail through a pop can and filled in the hole with it, works great.
I saw a video of them doing that not long ago. I heard tinning gets the best results. Getting the material on both parts before trying to join together
I saw that demo at an agricultural show in Australia in the 90s and haven't seen it since!
Thank you brother for this video. Cool and informative.
That’s pretty cool I have seen it on tv and it was way more expensive, thanks
heat is the key and I can never seem to get enough heat into an intake manifold to repair cracks. AL cans is the commercial for this stuff as its fast to heat, much more challenging to braze something you can actually use. Fuel tank was a good example, he "could not get enough heat" without really working at it. Torches will specify MAPP gas compatability as it destroys common propane rubber parts, ie. pressure diaphragms. Had a cheapo Bernzomatic propane screw on torch start to leak and ignite around the plastic regulator while in my hand using MAPP gas with it.
