'''Soldering''', is a process in which two or more items (usually metal) are joined together by melting and putting a filler metal (solder) into the joint, the filler metal having a lower melting point than the adjoining metal. Soldering differs from [[welding]] in that soldering does not involve melting the work pieces. In [[brazing]], the filler metal melts at a higher temperature, but the work piece metal does not melt. In the past, nearly all solders contained lead, but environmental and health concerns have increasingly dictated use of lead-free solder for electronics and plumbing purposes.

There are three forms of soldering, each requiring progressively higher temperatures and producing an increasingly stronger joint strength:
