Solder - Wikipedia
Solder (/ ˈ s oʊ l d ər /,  / ˈ s ɒ l d ər /  or in North America / ˈ s ɒ d ər / ) is a fusible metal alloy used to create a permanent bond between metal workpieces. Solder is melted in order to adhere to and connect the pieces after cooling, which requires that an alloy suitable for use as solder have a lower melting point than the pieces being joined.
