Solder (UK: / ˈsɒldə, ˈsəʊldə /; [1] NA: / ˈsɒdər /) [2] is a fusible metal alloy used to create a permanent bond between metal workpieces. Solder is melted in order to wet the parts of the joint, where it adheres to and connects the pieces after cooling.
Soldering is a widely used and effective way to bind metal components together. Soldering irons are super easy to use, and all it takes is a little practice and some safety precautions to have you soldering like a pro. With safety gear on, heat up your iron and touch it to the metal pieces you want to join.
