This is the incredibly simple way to solder aluminum that you can imagine. With its help, anyone, at home or in the garage, can easily repair and restore any aluminum products, without any argon welding. You can easily make various structures from aluminum profiles and much more.
Now, in order to solder a radiator or an aluminum bicycle frame, you don’t have to go to a workshop and spend a lot of money, everything can be soldered at home.
With the right approach, soldering turns out to be no worse than a welded joint, but certainly more reliable than any cold welding, which is usually used as an alternative.
Will need
A gas burner does not have to be professional. A regular burner attachment for a gas cylinder is sufficient, or any other will do.
I will tell you in more detail about the specialized solder that you will need to purchase. This is a tubular powder solder specifically designed for soldering aluminum (why powder? - powder inside the tube). It consists of two components: a shell and a powder base inside.We won’t go into details about the chemical composition, there’s no need for that.
It can be purchased in specialized stores and is used in car repair shops. The most affordable way for everyone is to buy it at Ali Express - link to solder.
It’s inexpensive, I advise you to buy the package right away - it will definitely come in handy in life.
Soldering aluminum with a gas torch
We take the profile or parts that need to be welded.
Clean the surface with a metal brush. Alternatively, you can use coarse-grain sandpaper. The higher the roughness of the soldering surface, the better the bond with the solder.
We fix the connection with a clamp or other device. Turn on the gas burner and heat the joint.
We bring tubular solder. It melts and spreads along the seam.
The entire process occurs at approximately 450 degrees Celsius.
Solder has incredible fluidity and flows into any, even the smallest, cracks in the metal.
After distributing the solder, we warm up the connection a little more so that it is distributed and spreads out at the joints of the assembly as much as possible.
Let's sum it up
Personally, when I learned about such a simple and accessible soldering method, I was incredibly surprised. I think I managed to surprise you too, if of course you didn’t know about it before.
A few words about reliability. Of course, welding wins, since the structures are combined and mixed, but this method is not much inferior. If the connection bends, the part itself bends. The solder connection is extremely reliable and is quite capable of withstanding almost any load, as if the connection was cast.
The only thing is that if the soldering is not of very high quality, it is most likely that the torch was not heated sufficiently. In other cases, everything holds tight.
Now it won’t be difficult for you to solder a hole in an aluminum pan, make a tank from sheet metal, or make a rack from a profile.
Take the method into service and use it, friends! See you again!
