How to learn to weld?

Here we describe the process to be done at the time of welding, to avoid crystallized welding, which lose their conductive properties and break easily.

Practice making a pyramid!

Materials: * bare or unglazed copper wire with maximum caliber of 1.5 mm * tin (solder) * soldering iron * sponge * Soldering ointment

1. Clean the copper wire with the sponge to remove the dirt from the wire, thus facilitating the adhesion of the tin to the wire when soldering.

2. Straighten The wire of copper to make it as straight as possible and cut it into sections of 10 cm.

3. Connect the soldering iron and let it heat up

4. Make a reference grid on a sheet of paper and locate two unglazed wires perpendicular to their ends, hold it with a small piece of tape while applying tin cream on the surfaces to be welded.

5. Using the soldering iron, melt the ointment to clean the surface and heat too.

6. move close the tin to the surface and it will melt

Warning!!!!! Do not blow the tin to cool it, this will cause it to crystallize.

7. Repeat steps 4 to 6 in order to weld each intersection.

8. Follow the following pattern to make the triangular face of the pyramid.

9. Proceed to solder the intersections and perform the procedure with the 4 triangular faces of the pyramid.

10. Join the triangular faces with the base. Making welding points between them, thus forming the final pyramid as shown below:

GLOSSARY

TIN: Pure tin, called block tin, is a soft white metal with a silver-like appearance and luster; it melts readily (235°) and is somewhat lighter than copper, having a density of 7.3. It is quite malleable and can be rolled out into very thin sheets, forming tin foil; most tin foil, however, contains a good deal of Lead. [1]

SOLDERING IRON: a hand tool consisting of a handle fixed to a copper tip that is heated, electrically or in a flame, and used to melt and apply solder [2].

COPPER WIRE: is used in power generation, power transmission, power distribution, telecommunications, electronics circuitry, and countless types of electrical equipment. copper and its alloys are also used to make electrical contacts [3].

SOLDERING OINTMENT: is a mix of small solder particles and flux. It is used exclusively in the automated soldering process reflow soldering. It's very important that the spheres of metal are very regular in size and have a low level of oxide [4].
