Brazed aluminium joint strength test

Testing some of David Picchiuto's brazed aluminium joints

David's videos on this:

[MakeSomething]

Thank you for doing this! I always enjoy your methods!

[ratchetfreak]

now for the real question how much would a little triangle piece reinforce the joint.

[TheGeekPub]

This was fantastic! These testing videos are some of my very favorites on your channel!

[daytriker]

I would suggest the strength of the aluminum joint is only as good as the preparation & which aluminum weld rod was used. Project Farm has done a comparison of the assorted welding rods available & there is quite a range in the success of the test results.

Gotta love well made tests! Great video Matthias!

[JasonToewsFTW]

+Matthias Wandel I'd be happy to TIG some tubing together and send it if you wanted to compare.

[HeavyboxesDIYMaster]

I heard the bathroom scale called the suicide hotline ... Saying something about always being pressured into breaking joints.

[AaronCanaday]

Mathias just scienced the SHIT out of that.

[tjweim]

Enjoyable and highly expect nothing less but we always get so much more.
Thank you Matthias!

[ciberbri]

Love you guys. You so quickly and effectively jig and test and quantify the answers to my questions. You save me so much time.

[athiker]

I enjoyed your testing procedure, but I'm sure David's table will give him many years of service.

I think you've found a great niche Matthias. Your thorough review and explanation are very interesting and show a larger spectrum of understanding that we may generally write off. I may still use braising for low bend moderate sheer applications but upgrade to Tig or switch to wood joinery if resilience is a concern. I'm sure David got a kick out of the tests, it pretty much represents his expectations.

I love seeing crossover videos like this. It's awesome to see that my favorite youtubists are all one big community of makers

[chrPHlLP]

Great video, I'm so glad you did this. I enjoyed David Picchiuto's original video as well, and was curious about the strength of the joints with different forces applied. Questions answered, without even asking! Thanks!

[cmichaelhoover]

So, for my application of an aluminum air duct joint the brazed joint will work just fine! Thank you for a great test and video!

[rockindel]

love to see the friendly co-operation between you tubers, not competition, now I have another person to subscribe to (make something), because they worked together, looks like another cool channel

[smellycat]

beware all builders. if you dont use wood, Mathias will come and break your stuff!

[RiverTurning]

If anyone is curious... the yield moment strength of the aluminum tubing used is roughly 507 in-lbs. In most welding applications, you can typically get a welded joint stronger than the base material. I don't think that applies to brazed joints though. Anyway, the load applied by Matthias was roughly 195 in-lbs. Approximately 38% of the strength of the tubing.

I want to use this method of brazing aluminium to make a shooting rest for the front of a quad bike. At first I was worried that it might not be strong enough but after watching this I don't have any concerns. Thanks for making the video.

Thanks Matt. Another thought-provoking session. After your video, YouTube automatically started another video on a similar subject but I had to turn it off because I found the so-called background music distracting and annoying. So many thanks for not putting music on your videos; well done you.
