Soldering

Soldering is a joining process used to connect metal workpieces by melting and flowing a filler metal (solder) into the joint. The solder has a lower melting point than the workpieces. This creates a strong electrical and mechanical bond through the wetting action of the molten solder. It is a versatile technique used across various industries, including electronics, plumbing, jewelry making, and automotive repair. The process typically involves cleaning surfaces, applying flux to prevent oxidation, applying heat, and then the solder. The quality of the solder joint depends on factors like temperature control, the right type of solder and flux, and a clean surface. It's different to welding which melts both pieces being joined.
