=====Description=====

'''Hard Soldering''' is taken to include those metal joining techniques in which a filler rod is used as the joining medium, heat is provided by a gas torch and there is no melting of the parent metal. In this context, it includes [https://en.wikipedia.org/wiki/Brazing#Silver_brazing '''Silver Soldering'''] and [https://en.wikipedia.org/wiki/Brazing '''Brazing'''] but not '''Welding'''.

By contrast, '''[[Soft Soldering]]''' is a method of joining metals with a '''[[Eutectic Alloy|Eutectic]]''' Tin/Lead '''[[Alloy]]''' and the heat source is often a '''[[Electric Soldering Iron|Soldering Iron]]'''.

=====Silver Soldering=====

'''Silver Solder''' is an '''[[Alloy]]''' of [https://en.wikipedia.org/wiki/Silver '''Silver'''] and a small amount of [https://en.wikipedia.org/wiki/Brass '''Brass''']. The addition of '''Brass''' is to lower the melting point of the '''Silver'''. The amount added will determine the actual melting point of the solder and this allows the creation of different grades of '''Silver Solder''' covering a range of melting points - typically '''Hard''', '''Medium''' and '''Easy'''. A [https://en.wikipedia.org/wiki/Silversmith '''Silversmith'''] for example, may have to solder several times during the creation of a produce and a range of melting points enables successive joints to be made without melting previous ones.

Joints to be soldered must be clean, close fitting and may need to be wired or held together in some way to avoid distortion during subsequent heating. A '''[[Flux]]''' is need to prevent the joint becoming contaminated with [https://en.wikipedia.org/wiki/Oxide '''Oxides'''] and to help the solder flow. Common household [https://en.wikipedia.org/wiki/Borax#Flux '''Borax'''] is suitable and much used by [https://en.wikipedia.org/wiki/Silversmith '''Silversmiths'''] and [https://en.wikipedia.org/wiki/Jewellery '''Jewellery Makers'''], but proprietary '''Easy-flo Flux''' is a convenient ready-made alternative.

A typical soldering technique is as follows :
* wire the joint together with soft iron binding wire,
* ‘paint’ the joint with '''[[Flux]]''',
* place small ‘Paillons’ of solder along the joint,
* use a gas torch to heat gently to start, allowing the '''[[Flux]]''' to dry out and melt without disturbing the solder,
* increase the heat and raise the temperature to red heat to make the solder melt then flow along and through the joint.
* allow to cool, remove any wire binding and '''[[Pickling|Pickle]]''' to clean.

=====Brazing=====

Brazing [https://en.wikipedia.org/wiki/Spelter '''Spelter'''] is a [https://en.wikipedia.org/wiki/Brass '''Brass'''] which is used as the filler rod when [https://en.wikipedia.org/wiki/Brazing '''Brazing'''] steel and similar materials ''(i.e. not '''Brass''' or '''Gilding Metal''', for example, since these would also melt at the temperatures reached during the process)''.

[[File:Brazing2.png|Brazing|300px|right]]
Most heat joining techniques work best if the joints are clean and close fitting but the '''[[Fluxes]]''' used in '''Brazing''' ''(e.g. SIF)'' tend to be ‘active’ in that, in addition to shielding the joint from air, they also clean it to an extent and are therefore more tolerant of surface contamination.

A typical '''Brazing''' technique is as follows :
* if required, wire the joint together or hold it within a '''[[Jig]]''' for example,
* using a gas torch or a welding torch to bring the joint up to bright red heat.
* warm the end of a length of '''Brazing Spelter''' and dip it into '''[[Flux]]''' powder.
* introduce the '''[[Flux]]''' coated rod to the heated metal and melt both together into and along the joint.
* allow to cool slowly and clean mechanically ''(e.g. using '''[[Emery Cloth]]''')''.
