Soldering is a process of joining two pieces of metal together using a lower-melting point metal alloy, called solder. A soldering iron is a tool used to melt the solder and apply it to the joint. Soldering is used in a wide variety of applications, from electronics to plumbing to jewelry making.
Soldering provides a strong and permanent bond between two pieces of metal. It is also a relatively inexpensive and easy process to learn. However, it is important to use caution when soldering, as the iron can reach high temperatures and the solder can contain harmful fumes.
