What Does Brazing Gun Mean?

A brazing gun is a welding device used to join two metal pieces together by generating and projecting heat from a contained electric arc struck between two electrodes, or between an electrode and the metal surface to be treated.


Corrosionpedia Explains Brazing Gun

Brazing guns are used to adhere two or more metals together by increasing their surface temperature in order to melt a filler metal that is contained in the gun. The filler metal is heated within the gun and used to bond the metal pieces together. The filler metal typically has a melting temperature lower than the corresponding melting temperatures of the metals to be adhered. In addition to a filler metal, a wetting liquid is used, which supports the flow of the filler metal across all jointed portions of the component metals to be adhered. The wetting liquid also facilitates cleaning and bonding reactions.
