Aluminium welding rod?

[dragonov_elite]

I was wondering if any one on tuners has came across this product before, What they have thought about it?

YouTube - Durafix Aluminum Welding Rods

Dura Fix Aluminum Welding Aluminum Brazing Aluminum Soldering & Repair Rod

I bought a small amount of material very similar to this product it is just a different brand name. If know one has any experience I guess ill be the test rat on it, I will write a review on it.

It's garbage. I tried something like it in high school to try to weld an aluminum frame . It flowed nice and all, but the welds just fell apart when any force was applied. I ended up just using steel and MIGing that. There is just nothing inert there to keep the metal from oxidizing from the heat and gases of the torch. I don't see what some redneck smashing a soda can shows anyone about the product. He should weld up a SMIM with it and pressure and heat test its durability, and it will likely fail within seconds.

Thats not a rod, as much as it is just a aluminum piece of metal. The above information is INCORRECT. YOU CAN WELD ANYTHING with a torch.. you just have to know how to braze. The aluminum is hard to weld because it has a hard oxidizing coat that is a problem with all aluminum. That rod will work as long as you have a torch that can get hot enough and you have to correctly brush the top of the metal to weld it. You dont need an inert gas with aluminum and brazing because the oxidation from the torch causes the metal to melt together and bond correctly. I wouldn't suggest this as the best tool for the job, but if you know how to braze it is really cheap and anyone can do it. Inert gases apply differntly to differnt welding, smaw,fcaw,mig/mag, or tig..

i've been a union pipefitter/welder for 9 years, so pick your advise..

The product is crap. Why do you think these products aren't sold in stores, or used by serious industry? Because it's wrong. It can work, but it's not proper and would never pass for any kind of industrial standards. It's for backyard ghetto riggers. You can't expect to melt aluminum in an oxygen environment without pitting reaching fully inside. Welding is not brazing. Brazing is soldering with a different name and higher temperature. I don't care about someone's profession that's somewhat related but wholly unrelated to this post.

 

[Dsm4lyfe12]

Once again INCORRECT. Brazing is done with a torch. How do you think they welded in the 60's, 70's,80's? By brazing metal, the only problem with it is its slow and companies are all about the money.Most Aluminum will never oxidize, considering its the reason on why you have to brush the metal to break some of the oxidation coating. Go spend 10 grand on a tig or mig welding machine, miller or lincoln, and then tell me what modifications you could have bought with that. If its a simple repair then i would definitely braze it. Obviously you dont break the oxidation coating you just melt more molecules into the metal that will also NEVER oxidize. Learn how to braze, try it and post back. Obviously if you reread the website that rod is basically aluminum filler rod that you would use to BRAZE.

Cuntsack,

Why do you continue to make yourself sound like an idiot. Brazing is not soldering, not even close. Just shut your mouth and go away. All you had to say is, "i havent good luck with it working, but it could work for your application" But no, you continue to argue things you have no idea about and troll this forum in the worst way. You arent a good troll. Go away ###g.

 

[Dsm4lyfe12]

Clean area to be welded down to base. Brush the base with stainless steel brush till shiny. Heat the area to be welded, evenly. As you heat the base, rub the rod vigorously against the heated piece to be welded till rod flows. Never apply heat directly to rod.

Read and reply...read and reply..

Tensile Strength,lbs/sq. in. 47,000 47,000 pounds to break that weld so its obviously a piece of shit. Oh and it has a great ductility rate, which means it bends.

And soldering isn't done with a torch? I guess people soldering copper pipe together in a basement is a figment of my imagination They've had oxyacetylene torches and other gas torches around forever. They didn't weld aluminum in the past, at all. Hence why it's referred to as a space age metal and is now used in everything, because we can now weld it. Look at all the old airliners that use aluminum, all the Boeing jumbo jets, they're all aluminum and titanium held together with rivets. Now we can weld aluminum, and it's not done so with torches, at least not professionally. I solder and I have brazed. It's just like soldering. It's just a cooler-melting, softer filler joining two harder, higher temperature metals.

These aluminum welding rods have always, and will always be infomercial type advertising and companies. It's fine for patching a hole in a soda can or small pin hole in a pipe.

Soldering is typically done with an electrical current. I dont think you would want to solder a motherboard with a fvcking torch.. They didnt weld aluminum on airplanes because IT TAKES LONG and they were mass produced. Things that were hand made were brazed for holding 47,000 pounds before you break that weld, on a BRAZED piece of metal.

They've had oxyacetylene torches and other gas torches around forever.

Obviously it only takes so long before you realize that you can REINVENT THE WHEEL.

 

[Dsm4lyfe12]

Lol, You could not weld a soda can. You would have to solder it.

 

[ramsack]

How is soldering typically done with an electrical current? Wire welding, arc welding, all of that stuff is done DIRECTLY with an electric current. Soldering irons are heated with electricity, but they can also be heated with a torch (ever see a butane pencil torch with a iron attachment?) Yes, most people think electronics when they think solder anymore, but that doesn't mean that's the only think soldering is used for. You could solder pipes with an iron if you wanted to, granted it makes enough heat. This is why a torch is used on pipes and not a PCB, along with burning it to a crisp. I guess you don't solder pipes in your mind, you braze them since you use a torch to do it. They didn't weld together Boeing jet liners because they didn't have the technology to do so, or they would have. Even look at the spy planes they built back in the Skunk Works days, riveted. They didn't mass produce spy planes, what were their excuses for not being welded together completely? And the military always has higher tech than industry, by at least 50 years.

You are both kinda right. My $.02. A rig has a torch. And when you weld copper in certain cases you use silver solder.

Bought some of those rods at a car show about 15 years ago....I couldn't repair shit with them. No matter how hot I get the metal, the rods just seemed to fall apart like they do around 1:20 in that video, or the material would all run off whatever I was trying to repair...or both.

I burnt through almost the entire package of rods and ended up fixing whatever I was working with using JB Weld.

I'm not a fan.

 

[ramsack]

If you join 2 piece of the same metal together (copper) using a dissimilar metal (silver) it's not welding, it's brazing, or soldering.

 

[Dsm4lyfe12]

The cost for having to pay men for 1000+ hours of labor, that is the excuse for not welding any airplane back before mig became popular. Lol, The thing that differ's from me and you is i weld with pipe, aluminum, and copper every single day for 12 hours a day. I might not know the most about my dsm, but something i sure as hell know alot about is welding. I will argue this point with you untill im dead, so please continue to ask me why they didnt braze jet planes.

Exactly what happened with me. They turn to powder. Welding together 2 pieces of forged aluminum looked like cast aluminum when the weld broke.

 

[Dsm4lyfe12]

Agreed, i wouldn't buy that rod personally. But, i would get actual filler aluminum and a oxy acetelyne torch. Ill do some aluminum brazing today and show you you guys .

 

[ramsack]

You are going back and forth so much here. Saying they didn't WELD planes because of man hours (which would only apply to mass production, not a few spy planes that were top-secret and produced over years' time) and then going to ask me to keep debating why they didn't BRAZE airplanes. I really don't care what anyone's job is. Just because you work doing something doesn't mean you are the global authority on that subject.

You don't braze with similar metals, you weld with it. Brazing and soldering are using a filler metal of lower melting point to join 2 other metals. They don't even have to be the same.

If you really think you can structurally weld aluminum with a torch I really don't want to be in or around anything you've worked on welding or brazing.

No im saying THEY DONT BRAZE AN AIRPLANE, simply because of PRODUCTIVITY, and MANHOURS IT WOULD TAKE. In the 1930's pay somebody 5 dollars an hour for 1000 hours to braze an entire airplane and you would be BROKE! Its not having global authority its doing it and succeeding at it. Now, understand that ALUMINUM filler rod has 47,000 sq lbs of tensile strength. If you know how to braze/ weld correctly you could weld/braze that to handle 47,00 pounds before it will break. The reason why im telling you my profession is because learning is time spent.. that being said i've personally spent years welding. And my father has been welding for 45 years. So if that isnt a personal experience with brazing and welding i don't know what is. Do you honestly think Justin learned all about turbos in one day? Oxy acetelyne welding was the most popular way of welding anything in 20 years in the past, it is cheaper for home consumers to buy instead of spending a TON of money on welding machines. I have a 43k rig for my job that i personally payed for.

 

[highlandgst]

just gonna say im trying to get into welding here soon ... and i know nothing of it so far . But damn is it amusing to watch you guys argue

 

[wishihadatalon]

Facts, found here Welding - Wikipedia, the free encyclopedia about welding vs. soldering and brazing.

Also fact, you CAN weld aluminum with a oxy/fuel torch. A special flux is required to create a stable atmosphere so that you do not contaminate the base material. It is a welding process, not a braze or solder.

As for the original post, I would steer clear of that stuff. If you do not have the equipment to weld aluminum, take it to a professional.

I brazed my intercooler pipes together with a MAPP gas torch and aluminum brazing rods from harbor frieght. Haven't had any issues up to 25psi

Thank you!
That's the information I was looking for.
