Soldering is a process of joining two pieces of metal by melting a lower-melting-point metal alloy (solder) into the joint. A soldering iron is a tool used to heat the solder and the metal pieces to be joined.
Over time, the tip of the soldering iron can become dirty or oxidized, which can make it difficult to solder effectively. Cleaning the soldering iron tip regularly is therefore important to maintain its performance.
