Soldering is a low temperature thermal joining process which can be used to join most common engineering metals and alloys. After heating, molten solder is drawn into a capillary gap between the metals to be joined.

A liquid low temperature Solder flux is also available for use with the above alloys

Soldering differs from brazing in that the filler metals employed have melting points of less than 450  C. Brazing filler metals have melting points above 450  C.
