Its fine until you try to make some thing big with lots of pieces then the thing just falls apart when the heat spreads through the job, I tried this and just got really pissed off.
Welding? My ass! This is brazing, buddy!
any information on where to buy the aluminum rods and their specs?
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.
how to buy this product?...saif
I saw this man demonstrating this a few weeks ago at the Malvern Tractor Show at the Three Counties Showground Malvern. It is very strong, if you try to break the joint apart it breaks away from the joint area, it was quite remarkable. It is a Swedish product and the man here demonstrating it is himself Swedish
It is not even near welding... Maybe some kind of brazing or soldering.
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
That stuff melts at +/- 610F. 6061T6 becomes liquid at 655F or so.Good product, in the right hands.

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
Slight of hand by gluing thin metal, while showing a thick metal (Transmission Valve body)?
A great thing. Do you personally tried it? Is it expensive?
If you campare this white welding process youre nuts
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'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. :-(
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)
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?
@MrVirago1000 You can email him to order your own wire at alutighteurope@hotmail.com
Alutight does not flow, so, why do I buy this? Durafix flows like water.....
I have some extra left over from a project. Would you like to buy some? I can list it for you on ebay if you like.
Same as durafix and hobart low temp rods and snapon do them too
I use flux cored wire and it's much better . Also using Firinit Flux + dedicated wire, does a nice job on 1050 aluminum.
This is not "fusing" to the aluminum because the aluminum is not melting. This is a soldering process Welding is a fussion process
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
Amazon.
when he took that screwdriver and mixed that shit back and fourth i think he made it all FUSE together.
its normaly hard solder, and you can buy 2 meter for 10 -15 euro at ebay
LOL for people to weak to TIG
If you torch aluminium like that, it will become brittle, possibly crack and break easily in that spot. Maybe even what happened on the back side of that demo sheet, but you couldn't really see the detail in the video. Aluminium is just a bitch.
This is called Brazing...
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.
I remember this gimmick came out 15+ years ago on TV and now its back again.
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.
