'''Soldering''' ([[General American|AmE]]: {{IPAc-en|ˈ|s|ɒ|d|ər|ɪ|ŋ}}, [[Received Pronunciation|BrE]]: {{IPAc-en|ˈ|s|ɒ|l|d|ər|ɪ|ŋ}}), 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|lead-free alloys]] for electronics and plumbing purposes.
