Soldering is a process of joining two or more metal items together by melting and flowing a filler metal into the joint. The filler metal, called solder, has a lower melting point than the items being joined. Think of it like using a special glue for metal that melts and then hardens to create a strong bond. Soldering is often used in electronics to connect components on a circuit board. Unlike welding, soldering doesn't melt the base metals being joined. Imagine carefully applying a soldering iron to create a secure connection between electronic components.
