Soldering is a metalworking process that joins two or more metal surfaces by melting and flowing a solder alloy into the joint. Solder is a fusible metal alloy that has a lower melting point than the metals being joined. When the solder melts, it flows into the joint and solidifies, creating a strong and permanent bond.
Soldering is used in a wide variety of applications, including electrical work, plumbing, and jewelry making. In electrical work, soldering is used to connect wires and components together. Soldering can also be used to repair damaged wires or components.
