How to solder?
Ask any man at least a plumber, even a programmer, they will tell you that a soldering iron is an irreplaceable thing. It will help to connect any metal (and to a large secret and plastic) parts, be it pipes or microcircuits.
How to solder - useful tips
To interconnect the necessary parts, you need to solder them. In fact, it is the melting of the metal (solder) on the surfaces to be joined, which, freezing, “grasps” them. With the help of solder and soldering iron, you can solder unnecessary holes or strengthen parts. How to solder? We offer you some tips.
The first. Clean the parts to be joined or their surfaces with sandpaper and degrease with gasoline or acetone. This will ensure that there are no extra substances on the surface that may interfere with adhesion. It is also necessary for perfect soldering to clean the surface of fats and metal oxidation products (in most cases it is rust to some extent or another). This is done with acid solutions and special fluids 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 your workplace so that there are no flammable objects or anything that can be damaged. Do not solder on a plastic window sill under the curtain. Immerse the end of the soldering iron in rosin or in ammonia powder. This will clean the soldering iron from 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 holds the soldered parts quite firmly. Solder can be found in the form of sticks, sheets, strips and powder, however, it could previously be in the possession of the owner in the form of an ingot or a shapeless lump, if it was often used. If you did not find a solder on the mezzanine in the depth of the house, you can freely buy it in the store.
So, how to solder a soldering iron: immerse the hot soldering iron in the solder until it gets very hot. It should envelop the soldering tip and assemble on it. Heating, grab the solder (it will gather on the soldering iron with a small drop), transfer it to the place of soldering parts and level the solder on the surface.Then add more solder to the desired strong connection or until we close the required area.
Fourth. After the solder has completely solidified, wipe it with a damp cloth and clean the surface with sandpaper or a file, leveling the surface.
How to solder wires and pipes
How to solder the wires? The secret is that the wires, unlike other metal parts, are very thin, they are easily damaged, and they are usually in a protective sheath, so there’s no need to treat them with a strong acid solution (flux), it is better to dissolve the rosin in ethanol and clean it wires before soldering this particular mixture.
How to solder pipes? Since they are usually made of copper or brass, a strong acid can also destroy them, so it is better to clean them with either a special flux or using aspirin dissolved in water, this will be the weakest acid solution. Connecting water pipes that do not have to pass water, use a large amount of solder, completely closing the junction so that there are no holes left in it. You can check after solidification by running water through the pipe.If leakage is detected, apply additional solder after 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 used to solder parts to each other? It is necessary to apply the paste to the place of adhesion and then heat it with a flame of a lighter, candle or alcohol burner. It is necessary to heat until the solder is released from the paste, - under the crust on the surface, you can see the shiny metal.
Now you know how to solder, and everything is in your hands.
