How to WELD Aluminum Without a Welder, Alumiweld, Aluminum Welding, Aluminum Brazing

In this video I will show you how to weld aluminum using brazing rods.

Items used:
1. Welding Torch (Harbor Freight)
2. Alumiweld Rods (Harbor Freight)
3. Propane Tank
4. Aluminum

Welding and brazing are two different processes. Welding involves melting the metal of your part and adding molten filler metal so the two parts become one. Brazing involves heating your part (but not melting it), so that it can receive filler material (brazing rod) through capillary action. The filler rod is not aluminum, but an alloy that melts at a lower temperature. In brazing the two parts have not become one, as in welding, but are connected by the filler material. Brazing is akin to soldering. It is a good application for ornamental metal work, or light duty applications. It is not appropriate for structural work. Thanks for the video.

Nice demo. The problem is that brazing does not melt the aluminum itself. It is a soldering method. It is great for home projects, like I am doing. It is pretty tough. Now, if you look at the metal in the middle, where the two strips overlap, there is no material in between the two. To melt aluminum, we need a temperature of over 1000 F. Again, I love brazing, but I would not use it in a place where lots bending occurs. There you need TIG, where the aluminum melts and you just add the filler to keep the two joints in place.
Brazing is great for lots of hobby use.

I'm honestly making a Panjo and need to make a spoon melt into the pan then tie the strings to it worked great surprisingly

Good job ....Never Knew you can weld like that ...Going Harbor Freight right now get one ....thnx

I have used the rods before they work good it's amazing how cheap it really is thanks for the content I subscribed as well. Hope you put out some more how to videos they really help people!

Very nice instructional video. Very well thought out, very good verbal instruction and describing in detail what you were doing. One thing is instead of using Propane, I would use MAP gas which comes in the yellow bottle/canister. My father and grandfather were pipe fitters and anytime they did any soldering on copper pipes at home or on jobs they would use MAP gas because they said it burned hotter. Aluminum is tricky because it conducts and dissipates heat and cold really well, so getting the aluminum really hot might help the aluminum stay hotter longer and the Alumiweld to flow better. All in all a very good video. Thank You.

I am impressed with your "solder gun" for this purpose. I have long used a standard "solder gun" for plumbing, but you have to hold down the "start" button to keep the flame going. Your gun seems to have an "always on" switch which works great for this purpose.

Great video, very simple and common sense, thank you. This video has made it easy for me to decide to do my own project.

Great job thanks for sharing some knowledge 👍💯

You’re having trouble with low heat because the steel vice is acting like a heat sink and drawing off the heat. Elevate your parts on something to fix it.

I have an aluminum car wheel that bit a curb and the "bite marks" are cosmetic do you think brazing them and then sanding them smooth would work or should I get it welded..the wheels holds air without any issues and the damage it near the lip that wheel weights would go but I use tape weights

[noduh]

Is it better to use a hotter burning gas like map or maybe even oxycetaline and do you need to use flux

[johnpearcey]

This is not welding. It's brazing. You should also use some flux which helps stop any oxidation taking place. It also helps the molten rod flow into the joint between the two plates. If this does not happen, then you are likely to have what is called a 'dry' joint and it will easily break. Contrary to what a lot of people think in these comments, brazing is not inferior to welding. When done properly, brazing can be as strong as a weld, possibly stronger depending on the type of material used in the brazing rod.

I'm trying to delete/block off Rear A/C I wonder if I can use this method to weld the lines shot?

They are a 3/8 and 5/8 aluminum lines

[jovansanchez]

Which exact rods did u get from harbor

[nvwonqc]

where does one purchase the welding kit?

[BaroudeurAventure]

Thanks for the vid. Is the aluminium softer after brazing or does it recover its strenght? I wanna weld aluminium pipes to make a load carrier.

[JC-msrz]

Everyone says use MAP gas but theses days you cannot buy it anymore (at least in the tree hugging republic of California), only this stuff they call MAP-PRO which is just a fancy propane gas...

[johnstanke]

I have tried these soldering method. The rod always turns into a blob. Never sticks to the surface. Always breaks off.

How well will this work for fixing rivets on a john boat?
