Aluminum Brazing/Welding For Beginners 

Thanks for the tips!

So does normal silver solder work for aluminium??

Boots do you think the rod he used would work on a vehicle AC high side line? Or do you recommend something better? I'm trying to fix a corrosion pin hole in a part that will cost $2400 In labor to replace.

Update these rods will seal a hole in the high side of a Ford Explorer auxiliary unit, With vigorous cleaning and prep.

​@SVTFordxx it will work, especially if you prep well. If you think about the big picture of aluminum brazing, you want the surfaces to be as "clean" as possible to get the most adhesion. So if it were greasy, slightly painted, etc. you don't have the ideal surface. With a good prep the rods used in this video have a strength of 33,000 psi (ie. 33kpsi).

You're very welcome & thank you! Its fun to practice this🙂 Stay safe out there & stay tuned for new videos every week🔧

Thank you very much! I'm glad you found the video great & informative🙂🙏 Appreciate the feedback. Stay safe out there!

Its actually very simple but it does require some practice. What this video didn't show was me melting the aluminum the first try haha Timing is key because these rods melt between 720-750 degrees F and aluminum melts at 1,200 degrees. Just something to keep in mind. Thanks for the feedback and thanks for watching!

I started to learn in high school along time ago, but didn't get far so I'm having to learn all over again.

@@JumpermanTech So I guess there are less chances to melt the aluminum by going propane than MAP gaz?

​​@@JumpermanTechis there some sort of temperature probe available to see what temp a torch or aluminum is?

Maybe a laser temperature gun could help​@@DoctorDiz

Haha thank you! I hear you on that one. Been seeing aluminum coils in the newer units these days & was wondering how to fix a leak myself. These rods melt between 720 & 750 degrees & aluminum melts at 1,200 degrees so the amount of heat applied is critical because you WILL def burn right through that aluminum. The thickness of the aluminum will play a large role. Thanks again! This was fun to do & you can work on many interesting projects on the side with this. Enjoy your weekend

Jumper man Tech what’s the strength like ,awesome video straight forward no b.s cheers 🍻

Thank you Garret! Appreicate the feedback & support. You may know nothing now but you are learning! Keep those dreams alive & you will become a bicycle frame builder. Manifest it! These aluminum brazing rods are good for small projects rather than for a bicycle frame but it's great to know for small repairs. I'd def look into welding. There are many types. Have a great day & thanks for watching!

@B He can do costum-work-bikes, if he set's up his workshop in the right neighbourhood - and invests some time in good online appearance too. Not everyone want's a Chinese-robo-frame

Garret Gartner, have you taken any frame building courses, or welding/brazing? The material you choose to build with will decide how you join the tubes together. I have an aluminum trike that has its tubes glued into lugs. ALAN built bikes in the seventies using the same technique. Fillet-brazed light steel alloy 531 and 753 were all the rage before aluminum and unrecyleable CF. Good luck anyway.

RadBrad, bicycles have been around since before robots were even in a play. Lotsa frame-builders out there today.

You're welcome & thanks for watching!

Hopefully you never did this to a rim. This does not actually weld anything.

Just heat up the aluminum enough that you can braze both sides of the joint at the same time before it cools. That way you do not need to worry about one side melting while trying to braze the other!

Thank you! Appreciate the comment & you watching🙏🙂

You should use a helicoil, make it better than new.

@@ih302 I love helicoils.

Cannon SL1 for this video. For action videos at work I use a go pro on my head. I use "Shotcut" to edit. It's free so check it out! Thanks for watching🙂

Yes, it held. For this demonstration I only did one side but I would recommend doing both sides. Thanks for watching! 🙂

Sure why not🙂👍 It's not so strong but it works! Thanks for watching👀

Yes but look up aluminium bicycle frame building, using lugs and brazing to join the pipes. Building a roof rack will follow a similar procedure.

Thank you! These rods aren't so strong so I'd say it's a cool/good idea as long as it'd a lightweight project🙂 Roof rack for a car?

@@gatekeeper84 👀👍🔧

Thank you very much John🙏 Appreciate the feedback. Brazing both sides would for sure improve the strength of the joint. Best bet would be to hit both the front and back at the same time after heating up the aluminum. I didnt use any flux. It sells as aluminum brazing and welding rods. Flux would help but it's not required as far as my knowledge and experiment

I'm an excellent steal welder, I have not welded aluminum yet and really want to try this! I am really good with science and can't see how Flux would be nessisary with how soft aluminum is because the bond would be made instantly unlike welding steal because the metal is so hard. I am really curious of the rigidty when melted together. I was told my affordable Canadian tire welder was a beginners welder! What a crock of shit that was, it did a 2000 wrangler body and cab frame rails with no problem minus the serperate body frame where I had to use arc because of the metal thickness! (Unrelated) Its the people welding that makes this all work and the honesty of the products! $225 welder with alot of time put on it and still working just fine. I also cool it though with a compresser on the noodles so the wire doesn't stick

Lol, unrelated to anything thick! Hopefully the project turns out amazing!!!!!!!!!!

@@MrSlaughterRosslyn been thinking of making a roof rack using this same technique. Wondering how it went for you?

Infrared temp gun w a laser so you know where you’re aiming it

AL3 rods are flux coated. You should wire brush the brazed joints after they cool to remove oxide buildup.

🙏🙏🙏🤘🤘🤘

Yes you can if your work piece is not too big, otherwise the heat will dissipate, like in cpu cooler, only way is try it out :)

Me too let me know what you’re using

I'd recommend these rods for small projects. This stuff isn't so strong honestly. Thanks for watching!

@@Diego-eh2nm 👀👀

Thank you! These rods aren't strong. I was able to break apart the joint by hand. Brazing both sides ass strength but I'd recommend this for small projects👍 Thanks for watching!

@@JumpermanTech read that again lol

BERNZOMATIC makes these rods and they are sold as "Aluminum Brazing & Welding Rods" The back of the packaging says AL-3 4043 Aluminum Soldering Rod & then further down it says that it contains Zinc, Aluminum & Copper

Thanks for watching!

@@JumpermanTech that is good to know. Thanks! I will look for these at my local welding supplier. Good job on the vid and thanks for responding so fast. Cheers!

@@SS-ws8bf Thank you🙃 You can find these easily on amazon & your local home depot as well✌

A commonly used cleaner is acetone or brake cleaner. Apply to paper towel, rub damp towel over surface, get a clean towel and repeat process until towel comes away clean.

These are brazing rods so he doesn’t need flux.

It's really not that strong at all. It's good for small projects. I'd say much weaker. Appreciate the feedback & thanks for watching!

​@@JumpermanTech Good to know. Thanks for posting this. It is a really good option to have since it doesn't need all the TIG gear and gas tanks for smaller and more cosmetic joints. Do you know if it can be done with an HHO torch or will the aluminium oxidise too much?

@@superciliousdudeYou're very welcome but thank YOU for your feedback🙏 Its def a great option! Its fast,simple & easy. I'm really not sure about the HH0 torch but that would be good to experiment. Just need to be careful and not burn right through the aluminum. The rod melts between 720-750 degrees Farenheit but aluminum melts at 1,200 degrees Farenheit so the amount of heat applied is critical. Thickness of the aluminum plays a large role

This is just soldering, it isn't welding. Welding is taking two things and fusing them to one solid thing. Soldering/brazing is just gluing them together.

@@wbaglivio That's why I asked how much weaker it is. :)

I'm not sure🤷‍♂️ Make sure you're getting hot enough temperatures that they melt👀 Thanks for watching!

For this video I used map gas. I would use either map gas or propane which you can pick up at your local home depot or lowes. Thanks for watching & stay tuned for new videos every week🔧⚡️

@@JumpermanTech Really informative vids. i plan to make some aluminum mech keyboard shrouds/cases this should work, thank you!

@@paulgonzales1829 Thank you! The steps used in this video should work out well for that type of project. Good luck & thanks for watching!

👍👍👍

I'm sure it can fill it but look into the best methods to do so. This isn't so strong honestly👀 Thanks for watching!

@@JumpermanTech gotcha. I know what I've seen in your videos haha. So I figured I'd ask
