Alutight - Low temperature aluminium welding
HTML-код
- Опубликовано: 15 окт 2024
- I attended a hobby exhibition and came across this guy selling a product for welding Alu, Zn , tin and their alloys. It seems to be just what i was looking for as welding aluminium has been a pain for me in the past but with this method i can now do it with heat from a normal blowtorch. I cant wait to try it out but meanwhile this video is to show members of my local hobby club what it was all about.

I had the pleasure of watching and learning from Bjorn at a classic car show in Sheppton Mallet today and left as amazed and inspired as pretty much everybody else is! I purchased some " wire" from him and could not wait to try it out on some damaged Land Rover bodywork. Results were very good and very pleased with the product. You got to try it! I also practiced first on some bodywork off cuts to get my technique sorted. Highly recommended.
You are correct in your statement that this is not welding, however I am a Qualified welder fabricator, this stuff is brilliant very strong and is used within the aero industry. I tested a piece out by breaking it, the root pentration goes right through and snapped no where near the joint at all 3 sides to the T joint when I tested it. Have you used this product (alutight) or are you just making a statement without real life facts or qualifications?
Wow imagine the money saved those rods are costly I go threw them like nothing.. you have saved me thousands of dollars what priceless knowledge
By far this is the best video
I've done a fair amount of aluminium welding, the problem is softening of the aluminium and buckling it, you need a low temperature solder and a good flux, the best fluxes contained now banned substances I believe which explains their disappearance. A large piece draws heat away at a ridiculous rate
Are you sure it's not welding? At 2:10, he shows the backside of the aluminum where it's melted through. The heat from a propane torch is more than sufficient to melt aluminum as long as you do not have a large heat sink.
It looks to me like the wire is used to coat the aluminum prior to melting, which insulates it from the air, preventing oxidation buildup that way instead of using argon. Then it's all melted together and actually welded.
Home Depot sold aluminium solder 20 years ago called Zincit, worked well on my car AC condensor using a sleeve, and some other no load joins, but now not available.
I use it for hobby work & find it like soldering.It Evan joins brass to aluminium & good for motorbike parts also.It can join cast aluminium well to.But its important to rub it in well or it just lets go
Whilst i have no doubt in that this stuff will work for your chamber my biggest concern would be the heat ranges involved when in use (cold to very hot and everwhere in between, you dont say what fuel so i dont have an idea if that makes sense), your best bet for both the aluminium and the titanium would be to get it "Tig" welded by a professional welder, with good root penetration, for this type of work it needs to be someone with an ac/dc set up.
I saw exactly the same block do exactly the demonstration at Kempton Market on the 24th November 2015 at an auto jumble sake. Nice fella
This type of solder was sold in Australia in the flee markets many years ago but where banned because of its Mercury content . Just wondering if its same thing emerging some where else in the world.
I think you're confused, you can't weld/braze aluminium with anything containing mercury, mercury destroys aluminium on contact.
Looking at the amount of molten material around 1:41 it's far too much to be accounted for by the volume of rod applied so the work piece is definitely melting to a degree.
I have a demo T-piece weld from the Harrogate show several years ago and the underside has classic breakthrough characteristic of other types of welding on thin plate.
I don't care what you call the process I'm off shopping for some more of this stuff because it complements my MIG and TIG capabilities.

That stuff melts at +/- 610F. 6061T6 becomes liquid at 655F or so.Good product, in the right hands.
Cannot understand why the argument if it is welding, brazing or soldering, the question is does it do the job you want satisfactory and how easy is it to use and what cost. PS Brazing is using a filler above 450 deg C melting temp and soldering is using a filler with a melting temp below 450 deg C.
Also if a propane torch was able to melt aluminium then you would be able to braze with it in the traditional and true sense, this is only something that can be done with an oxy fuel process such as oxy acetlene or oxy propane or gas air mix. The nearest you will get to with brazing is silver or hard soldering with a propane torch which is a much lower heat
The ali could also be Mig welded but not the titanium, i have a bloke near me who does bits cheaper than i can do them for in Tig (i dont have to invest in yet more rod for a one off job if that makes sense and still cheaper too), the titanium would have to be tigged though, hence why not have both done at the same time (titanium will not be cheap)
A great thing. Do you personally tried it? Is it expensive?
This is a welding process, not soldering. The parent metal melts and is fused together. The way this works is that the filler rod forms an alloy with the parent metal that lowers the melting point. You have to scratch away the oxide layer with e.g. a screwdriver to start the process, and once the alloy is formed on the surface of the parent metal, it melts and quickly spreads through the material.
Hi there Rob.
Was wondering if u could help?
On using a single throttle body to bolted to it, I wish to create a plenum with velocity stacks, to bolt directly onto my engine block. Do u think this stuff or something else, flux like, is suitable for aluminium?
P.s. while I'm here, any suggestions for titanium?
Sorry if I'm being a pest & thanks for reading my questions 8)
Like to see it on 1/4" metal , What I have been looking for I have seen it before working on thicker bar. I just bought a light weight wheel chair
Made with beautiful aluminium low temp welds
Bonjour, quelle est la composition des baguettes ?
@1980phil2010
It is not hard solder. Hard solder does NOT fuse to Aluminum ..
This is not "fusing" to the aluminum because the aluminum is not melting.
This is a soldering process
Welding is a fussion process
NICE WELD 👏👏👏
I'm having difficulty using this on large aluminium objects.
Tried fixing a hairline crack on a bicycle frame, but couldn't get the frame hot enough with the torch as the heat just spread down the tubes of the frame.
:-(
I have several cracks in my Honda 530 GVX aluminum crankcase. I am going to attempt to weld it together with a propane torch. Should I apply aluminum from the inside or outside?
Id be scared to apply that much heat to a large piece since you could melt big hole in it because the piece will suck away until the whole thing get very hot.
Not to mention deformation...
Soldering is a process in which two or more items (usually metal) are joined together by melting and putting a filler metal (solder) into the joint, the filler metal having a lower melting point than the adjoining metal.
This is also what we say about brazing! I'd say what we see here is Aluminum Brazing, NOT "welding"! But people will call ANYTHING welding, especially on eBay! As a welding instructor this is one of the curses of my existence! There's more than a few, but having the terminology all screwed up makes everything else difficult.
Sir, can i ask what gas you use to heat up?butane gas only?
It is not even near welding... Maybe some kind of brazing or soldering.
welding
join together (metal pieces or parts) by heating the surfaces to the point of melting using a blowtorch, electric arc, or other means, and uniting them by pressing, hammering, etc.
ron dempsey Exactly. it's NOT welding. The parent material has not "been heated to the point of melting" This "weld" is just stuck on top of the parent material. It's just solder rebranded. Not nearly enough strength for anything structural.
ron dempsey Not quite correct, there are some recognised welding processes that do not apply or use heat such as solid phase welding.
It is welding! If you watch his display you will see the rod melts and mixes with the parent material. There is penetration on the other side of the join. There is no doubt, it is most definitely welding!
@@Mitch_C740 Incorrect statement. This is welding and not brazing. The base metal does in fact melt and full penetration is clearly evident. I had a go with this method yesterday and although initially sceptical I am quite happy that the two parts are fully welded. As a professional and Chartered Engineer for over 30 years, I'm not easily hoodwinked.
Hmmm seems like a hint of gallium might be in the wire?
I thought so too but the list of metals in the alloy would probably not work with Gallium since it destroys the crystalline structure of all of them. Even with trace amounts, Gallium would ruin the weld before the metal cooled to room temperature.
Only works on small pieces where heat can't dicipate
ok
Alutight does not flow, so, why do I buy this? Durafix flows like water.....
@Lechoslowianin
i paid about 30 GBP for 1 meter but i have not had time to try it out yet.
You might as well send it back
can one use this on aluminium mags rims?
NEED TO MARKET THIS IN THE US!! PLEASE! Ebay is a good start (hint, hint).
how to buy this product?...saif
It's called Alumaloy. It works great, as long as you prep thoroughly. At my previous job I used it to repair the aluminium frames rails of electric golf cars where acid from the batteries had corroded them. After taking all six batteries out, I would cut out the bad section of frame rail, cut a piece of identical aluminium angle stock to fill the gap plus ~1-2 inches, lay that piece over the gap, mark where the "weld" would be. Then, the MOST important step. Using a CLEAN STAINLESS STEEL stiff wire brush, I would abrade the area that was to receive the Alumaweld thoroughly. And then I would do it a little more. Then, just a bit more to be sure. Then, set everything back in place, fire up the propane torch, heat it all up and flow the Alumaweld rod in. After it was all cooled down, it was good to go. Because it was not a visible repair, I never did any grinding or anything to make it pretty. But I tell you, it was just as strong as original. The batteries that were resting on these repairs were 97 pounds each, and there were six batteries. Never once did I have a repair using this stuff fail. Here is a link to the companies website: www.alumaloy.com/
If you want to buy a small amount to try out, harbour freight tools sell a small pack for under twenty bucks. And yes, it is the real stuff, not a typical harbour freight knock-off.
Amazon
when he took that screwdriver and mixed that shit back and fourth i think he made it all FUSE together.
What rods are these, anyone have any links?
Looks like solder to me. Better to use a powertig and weld it properly if you need strength.
Hi, now that is an excellent product, welding Ali is such a pain normally , thanks
Note how thin the alloy is and how much heat applied...!? Useless on any practical applications..!
its normaly hard solder, and you can buy 2 meter for 10 -15 euro at ebay
I remember this gimmick came out 15+ years ago on TV and now its back again.
that is "glue" only do a mechanical joint , theres no fusion at all
Thank you very much 8)
Soldering
You haven't welded this. You've brazed it. It will be more than adequate for many purposes, and totally INADEQUATE for many others. Better know the difference!
This comment section is hilarious, they probably think gas welding is black magic.
Exactly 😆
Not at all welding. This is classed as brazing. If the parent metal is not melted and fused with another, it is brazing. When the filler metal can be melted with a low temperature propane, it probably is more accurately called soldering.
I am from the future. Im from the year 2020.
Don't buy into this
Its still not true welding as the apparent metal has had its molecular structure lowered in heat melting temp, it does replicate a weld within its characteristics of penetration etc but if it were to be used within an environment where it would be subjected to high heat such as a cooking vessel the fused joint would melt where as a true welded joint would still be ok, a propane torch will only melt aluminium of a thin a small area such as a drinks can but nothing more
Volvo cam cover I see
Am aluminum WELDER have a job me
THAT IS NOT WELDING. welding is fusing two pieces and rod together as one. what you are doing is soldering/ brazing. you just seem to have a type of solder/alloy that suits your experiment. - NOT STRONG
This is called Brazing...
kind of soldering..
I would only use a powertig welder on any aluminum that will be put under stress or that will carry a load.
If you campare this white welding process youre nuts
@MrVirago1000
You can email him to order your own wire at alutighteurope@hotmail.com
I have no ideal why people call this welding, it simply is not welding!, it's not even a true braze , if you want to really weld aluminum. You need to Eather get your self a tig or mig welder!!!
When he picks up the piece at 2:15, he shows us the bottom; looks like he melted through to the parent materials, and not just the braze rod.
Technically speaking, this is welding. Perhaps you didn't watch far enough in the video?
this is not welding , if you take a welding course. You will learn that brazing and welding are two different processes. Besides he did not even come close to melting the underside of the parent material, what you saw was the outer side of the parent material that he heated up, by focusing the flame in a vertical motion causing the parent material to discolor a bit, with zero penetration
Aluminium does not suffer heat discoloration like steel, and is easily melted with a gas torch, even butane. He very clearly states that the parent materials are melting, and the sudden weakness in the joint about a minute and a half in seems to perhaps support this. It sounds perhaps like you were only taught about MIG/TIG welding? Technically speaking, this is still welding, if the original materials melted as well. Do not confuse this with brazing, where only the solder / joining metal is melted.
besides if he was truly welding , none of those people would be standing around looking at him weld the aluminum, he would have to have a welding shield to protect the patrons from the weld ARK, AND he him self would have to use a welders helmet to protect his eyes? as well as to allow him to see the puddle of molten aluminum the welder will make, while he adds filler Rod!!!
جامده جدا
That's not welding. That's badly-done brazing.
Having used it, I can assure you it is welding and not brazing. This is not the same material as found in the past which I attempted to use and had no success.
LOL for people to weak to TIG
or maybe they dont want to pay 2k for a tig welder? grow the fuck up.
