    - Brazing is a soldering process in which a copper-zinc alloy, that is brass, is used as the joining medium.

    - Brazing is a form of hard soldering in which the welding alloy used in the joint is harder than solder, naturally joint is much more stronger than the soldering.

    - The brass used in brazing operation is also called as spelter.

    - Spelter has different composition depending upon the metals being joined.

    - It is necessary that the spelter should have a lower melting point than the material being joined.
