[header] How to solder [title] Learn what soldering is. [step] Put into basic terms, soldering is the process of melting a metal onto other metal components in order to bind them. [substeps] Soldering differs from welding. 
In welding, the component pieces are melted together; in soldering, a softer metal with a lower melting point is used to connect them. Because soldering doesn't melt components, it's useful for more delicate applications, such as electronics work, or plumbing.
