Sometimes there is a need to solder copper products. But how to solder and why? The unequivocal answer is no. The choice of which way to solder depends on what size and weight from the parts to be joined. Still it is necessary to take into account the burden that will fall on the soldered parts when using the product. Consider several ways to soldering, and you choose yourself the one that suits you the most.
1
Copper wire (electrical) or small Circuits easily warmed to soldering temperature, wherein the melted tin-lead solder. The same brazing and soldering is done. Fluxes are used in brazing such should be based on rosin. For example, soldering oil (such currently viscous substance) or rosin itself.
2
The surface of the parts that need to solder, cleaned of dirt and oxide film. After that, the details need to proludit. That is, in the mating faces of soldering flux is applied and a thin layer of solder which must be smoothed as flat as possible. Then connect the parts and heated up to a soldering iron until the solder starts to melt. Then a soldering iron is removed and the compound is allowed to cool. If solder dish, then use pure tin. It has a melting temperature higher than that of tin-lead solder.
3
When solder or large massive parts and can not warm up a soldering iron, the burner is used for heating, and the solder copper solder as flux take borax. In the copper solder, such as PMF7 (solder copper-phosphorus), a higher strength than conventional.
4
To solder this way, you need some tools and materials, namely gas burner, vices, pliers or tweezers, solder PMF7, flux (borax) and acid.
5
To begin with, the part is cleaned from dirt and oxide film. Can be sandpaper, and can be hydrochloric acid. After you hold the details that you need to solder, in the vice so that there is a small gap between them. Then apply flux and heat the items. When they decorate - bring the solder to the gap between the details. Solder will melt (it has a melting point below), and stained, fill the clearance. Give the parts to cool, rinse with water from the acid and you can read the work of the finished.
6
You can use the so-called hammer soldering for the soldering of massive parts. They are heated on open fire, for example, a soldering lamp. And then everything, as usual: the flow of flux, stroke, then join parts and warm them up with a soldering iron. As a solder for a hammer soldering iron, tin is more often used than other solders.
So we told you about several ways to solder copper parts, and you choose which method is needed.
