Welding aluminum at home without argon



In this article, the master will show us how to weld aluminum without argon welding. According to him, the compounds are strong, welding is very simple, and at a cost it is several times cheaper than argon.

The following tools and materials are needed for welding: aluminum scrap (tube, bolt, etc.), a propane torch, a vice, pliers, and the most important material is aluminum brazing wire. Such a master buys wire on Aliexpress.

The burner is also not simple, but for soldering low-temperature solders. The heating temperature reaches 1300 ° C.


Before welding the necessary part, the master advises to practice on unnecessary aluminum scrap.
For a weld to be durable, a certain temperature is needed. You can neither overheat the seam, nor heat less than necessary.

First, the master trained on an aluminum tube. I made a cut on it and proceeded. As the saying goes, "the first pancake is lumpy." The master overheated the pipe, and it melted. The second attempt was more successful, the only solder was slightly swollen.


Then the master tries to weld two tubes cut at an angle.



The upper part was soldered well.

The master welds the inner corner.

When trying to break the tube, the lower seam could not stand it, but the upper one was quite durable. The photo shows that the gap went to the side.


The next experiment with a profile pipe. The walls of the pipe are thicker and need to be warmed up more. When soldering, part of the material got into the profile, such moments must be taken into account.




Having cleaned the weld, a good result was obtained.

With the last step, the master welded a nut to the bolt. After the operation, the master decided to try to unscrew the nut, but he did not succeed. Those. the connection is strong enough.



Thanks to the master for useful instructions.

You can make a rivet from a stick of hot snot boss

I would see how he soldered a hole at the bottom of the can
- depending on which hole. If the hole is small and the can will not heat up., Then such an electrode is not needed. .... Poke a piece of plastic film through the hole and set fire on both sides (alternately). As it burned to the wall, pressed, and will serve you for many years.

Well, about TIG welding probably don’t know at all. drinks
And in general, I already had very old article about special electrodes for soldering.
And even more strange that a person who has mastered welding doesn’t know such simple things ... (I knew, I wouldn’t even have a thought, I would try!)))) ... I’m not talking about soldering-welding and What is the difference"....

I did not even look. You already decide the soldering or welding! Tin-zinc solder is used for soldering for at least 40 years. OTs ... And then China CHINA
I tried to solder with a welding electrode - it did not work

Strange !!! They solder everything with electrodes !! )))) And even more so, aluminum ...))) It’s very soft! )))

I'll try to weld solder, it suddenly turns out
I soldered the TV antenna with solder for aluminum, though the soldering iron took a powerful one, it worked fine.

Pancake!!! In how simple !!!
And the whole world did not even try, but immediately began to invent some kind of argon welding !!!

A simple option to weld aluminum is to buy electrodes for aluminum and weld without problems !!!
Soldering! This is soldering!
