you need
  • soldering iron, solder, flux, diethyl ether, copper shavings, copper sulfate, copper wire, electric battery.
Before the start of the soldering surface of the parts to be joined, smooth out a file, sandpaper, degrease gasoline or other organic solvent.Check and prepare the soldering iron.Good and properly heated soldering iron powder immersed in ammonia or rosin gives light smoke.
to use aluminum brazing soldering capacity of at least 100 watts and the solder, which consists of 80% tin and 20% zinc (or 95% tin and 5% bismuth).Use the flux of stearin or paraffin.When choosing a soldering iron, note that they can
be both the most simple, requiring an open flame heating, and electrical, including soldering spot (with the regulation of the heating power).
Under normal circumstances aluminum is difficult to solder, because on the surface after cleaning immediately formed oxide film.For this reason, after stripping the soldered surfaces of the place of the future connection to the aluminum or aluminum alloy immediately pour the molten rosin.
Dial on the soldering iron and solder transfer to a secure future surface rosin compound.Zaludit likewise aluminum, you simplify soldering.By tinned aluminum surface can be easily soldered, for example, copper wire.
second method of soldering aluminum strip the metal surface, brush it with a solution of rosin in diethyl ether.Then sprinkle with aluminum copper filings using sidecutters or sandpaper place usual brazing solder tin.
use as an electrochemical method for aluminum brazing.Strip the junction place and apply a few drops of the concentrated solution of copper sulfate.Thereafter aluminum component connected to the negative pole of the battery and the positive pole, connect a piece of her bare copper wire, which is incorporated in the drop of vitriol.In this end of the wire should touch the surface of the aluminum.After some time on the spot soldering future settles uniform copper layer to which the conventional method can now be soldered practically any metal.
