Soldering is a materials joining process used to bond two or more metal components together, typically at lower temperatures than welding. It involves melting a filler material, called solder, which has a lower melting point than the materials being joined. This molten solder is applied to the joint, where it flows and wets the surface of the metal parts, creating a secure and conductive connection when it solidifies. Soldering is commonly used in electronics, plumbing, jewelry making, and various other applications where a precise and non-destructive joining method is needed. Unlike welding, soldering does not require the base materials to melt, making it suitable for delicate or heat-sensitive components. The choice of solder type and technique depends on the specific materials and requirements of the project.
