Copper is a metal that hassufficiently soft, supple structure. Therefore, unlike the same steel, it is easier to solder such material than to weld it. With a strong desire, the availability of the necessary tools and tools to cope with a similar task, even a beginner can. Let's find out how to solder copper pipes.
Often, pipes made from thematerial, are used in the household when installing elements of heating and water supply systems. Copper is the optimal solution for creating such conductive paths. It has a perfectly smooth surface, does not corrode, is not blocked by deposits, and also has bactericidal properties. Finding out how to solder the copper heating pipes correctly, you can ensure the uninterrupted service of the system for several decades.
Before you figure out how to solder copper pipes, you need to prepare a set of tools that you might need in the course of the work:
At present, numerousvarieties of solders, which are capable of providing a reliable connection of copper pipes by soldering. Most often, masters resort to the use of low-temperature solders. The latter make it possible to create joints with a relatively low heating of the material, which does not cause deformation of copper. However, such seams are not the best mechanical qualities.
As for solders destined for solderingat the highest temperatures, they allow you to create the most durable connections. At the same time, they are recommended for use only by experienced craftsmen, since without the appropriate skills, prolonged thermal effects on the metal can lead to its burning.
How can you weld copper pipes together?When low-temperature soldering, which is common in the arrangement of domestic heating and water supply systems, most often resort to the use of lead-free solders. The latter make it possible to create a sufficiently stable connection to mechanical loads. Among such solders it is worth noting the alloys of tin with bismuth, antimony, selenium, silver. The main share in their composition is tin - about 95%. The rest is accounted for by additional components.
To perform a low-temperature soldering completelysuitable cheap solders based on tin and lead. However, they are not recommended for use in the construction of water pipes, which are designed to supply drinking water, since lead is a toxic material.
In the case of low-temperature soldering, usuallychemical compositions based on zinc chloride are used. However, trying to figure out how to solder copper pipes, do not pay too much attention to the composition of the flux. To solder copper, it is enough to purchase any product intended for these purposes, for example, rosin-vaseline paste.
Как паять медные трубы без флюса?It is quite possible to make strong connections without the use of chemical compounds. However, high-temperature brazing should be carried out using the best quality solders based on tin and silver.
How to braze copper pipes? The works are performed in the following order:
Существует ряд советов, которые могут пригодиться at performance of works. So, for masters who do not have an impressive experience of soldering copper pipes, it is recommended to practice beforehand, using pieces of unnecessary blanks as an expendable material. According to specialists, it is necessary to perform a trial soldering several times to form a general idea of such work.
During the heating of the joints, the burner does notsuppress the flame at one point, since its temperature can reach about 1000 ° C. In order not to burn copper, it is enough to evenly heat the section for 20 seconds.
When soldering is complete, a thorough flushing of the pipeline system must be carried out under a considerable head of water. This is the only way to remove surpluses of solder and flux that are frozen inside the joints.
So we figured out how to braze the copper pipes.With a responsible approach to the task and the availability of the necessary tool, everyone is able to cope with such work. It is important only to practice beforehand, without deviating from the technology.
