  How To Solder
Soldering is defined as "the joining of metals by a fusion of alloys which have relatively low melting points".
Soldering is also a must have skill for all sorts of electrical and electronics work.
Soldering irons are the heat source used to melt solder.

  Solder - Wikipedia, the free encyclopedia
A solder is a fusible metal alloy, with a melting point or melting range below 450 °C (840 °F), which is melted to join metallic surfaces, especially in the fields of electronics and plumbing, in a process called soldering.
Solder often comes pre-mixed with, or is used with, flux, a reducing agent designed to help remove impurities (specifically oxidised metals) from the points of contact to improve the electrical connection.
Since solder can occasionally splash (due to the superheated flux inside or from contact with water in the cleaning sponge), it is recommended that one always wear safety goggles when soldering.

 Soldering - Wikipedia, the free encyclopedia
Soldering is distinguished from brazing by virtue of a lower melting-temperature filler metal; it is distinguished from welding by virtue of the base metal not melting during the joining process.
In a soldering process, heat is applied to the parts to be joined, causing the solder to melt and be drawn into the joint by capillary action and to bond to the materials to be joined by wetting action.
Soldering can be done in a number of ways, including passing parts over a small fountain in a bulk container of molten solder (wave soldering), heating assemblies by use of an infrared lamp, or by using a point source such as an electric soldering iron, a brazing torch, or a hot-air soldering tool.

Solder is a tin-lead fusible alloy, although small amounts of other metals such as antimony, bismuth, or silver may be included to enhance its characteristics or make it suitable for a special purpose.
Solders with a 63/37 or 60/40 composition are the most free-flowing kinds and are particularly good for working on delicate printed circuit boards.
When soldering, place the tip of the soldering iron directly against the connection to be soldered, and at the same time apply the solder to the point where the iron touches the two pieces of metal.
