How to solder aluminum
Aluminum is a very attractive metal for constructing your own self-made structures: light, well processed, drilled, sawn, does not rust, etc. But here's the ill luck: it is almost impossible to weld two pieces of aluminum without special argon welding. And the equipment for such welding costs more than one thousand rubles. But it turns out there is a way! This is soldering! But not simple, but using special powder-rod solders.So it looks without packaging.The usual piece of wire looks, but not quite: there is a special powder inside this rod.
We needSo, what do we need to solder two parts one to another:
- Brush for metal.
We solder aluminum with our own handsWe proceed directly to the soldering. First you need to prepare the surface of the metals. We take a rough metal brush and clean the place for future soldering.
Bonding strengthOf course, this is not arc welding, but it does very well,neither is not worse. I managed to break the connection only by taking it at a kink! But here, it seems to me, and welding would fall off. So friends, the soldering method is reliable.
