How to properly solder?

Ask any man any plumbing, at leastprogrammer, they will tell you that a soldering iron is an irreplaceable thing. It will help to connect any metal (and for the most part secrets and plastic) details, whether it be pipes or microcircuits.

How to solder - useful tips

To connect the necessary details,you need to solder them. In fact, this is the melting of metal (solder) on the surfaces being joined, which, when frozen, "grasps" them. With the help of solder and soldering iron you can weld unnecessary holes or strengthen parts. How to properly solder? We offer you some tips.

First. Strip the connected parts or their surfaces with sandpaper and degrease with gasoline or acetone. This will ensure that there are no surplus substances on the surface that can interfere with the adhesion. It is also necessary for the ideal soldering to clean the surface of fats and products of oxidation of metals (in most cases it is rust to some extent). This is done with solutions of acids and special liquids like flux. So you not only complete the process of cleaning your parts, but also be able to protect them from rust.

The second. Clean the soldering iron - heated soldering iron. Be careful and equip the workplace so that there are no flammable objects or anything that can be damaged. Do not solder on the plastic window sill under the curtain. Immerse the tip of the soldering iron in rosin or in ammonia powder. This will clean the soldering iron of oxidized metals, it will be better to solder, and the soldering iron will last longer.

Third. Heat the solder. Solder is a mixture of low-melting metals, it replaces glue and keeps the soldered parts fairly firmly. The solder can be found in the form of sticks, sheets, strips and powder, however, earlier it could be at the owner in the form of an ingot or formless lump, if they were often used. If you have not found the solder on the mezzanines in the back of the house, you can freely buy it in the store.

So, how to solder soldering iron correctly: We immerse the hot soldering iron in the solder until it is very hot. He must envelop the tip of the soldering iron and gather on it. Heating, grab the solder (it will gather on the soldering iron with a small drop), transfer it to the place of spike parts and level the solder on the surface. Then we add more solder to the necessary strong connection or until we close the necessary area.

Fourth. After the solder has completely solidified, wipe it with a damp cloth and sand it with sandpaper or file, leveling the surface.

How to solder wires and pipes

How to solder the wires correctly? The secret is that the wires, unlike other metal parts, are very thin, they are easy to damage, and usually they are in a protective braid, so do not treat them with a strong acid solution (flux), it is better to dissolve rosin in ethyl alcohol and clean wires before soldering by this mixture.

How to solder pipes? Since they are usually made of copper or brass, strong acids can also destroy them, so they should be cleaned with either a special flux or with aspirin dissolved in water, this will be the weakest acid solution. When connecting water pipes that do not need to pass water, use a large amount of solder, completely closing the joint so that there are no holes left in it. It can be checked after hardening by letting water through the pipe. If a leak is detected, apply additional solder, pre-drying the pipe.

There are special mixtures that emit solder,which can be used without a soldering iron - solder paste. How can they be soldered to each other with their help? It is necessary to put the paste on the place of soldering and then to heat the flame of a cigarette lighter, a candle or an alcohol burner. You need to heat until the solder is extracted from the paste, - under the crust on the surface you can see the shining metal.

Now you know how to properly solder, and everything is in your hands.
