In the more common, more specific usage, brazing is the use of a bronze or brass filler rod coated with flux, together with an oxyacetylene torch, to join pieces of steel. The American Welding Society prefers to use the term "Braze Welding" for this process, as cappillary attraction is not involved.

A variety of alloys of metals, including Silver, Tin, Zinc, Copper and others are used as filler for both processes. There are specific brazing alloys and fluxes recommended, depending on which metals are to be joined.

In order to work properly, the base metals must be exceptionally clean and free of oxides. In most cases, flux is required to prevent oxides from forming.

Brazing is similar to solderingSoldering is a method of applying a lower-melting-point metal to join other metal parts using solder. Soldering can be performed in a number of ways, including bulk liquification, or by using a point source such as an electric soldering iron or brazing to but higher temperatures are used and the filler metal has a significantly different composition and higher melting point than solderA solder is a metal alloy (often of tin and lead), usually with a low melting point, that is melted and used to join metallic surfaces, especially in the fields of electronics and plumbing, in a process called soldering. In electronics, tin/lead solders a.

Brazing is different from weldingWelding is the joining together of materials (typically metals or thermo plastics), usually by a fusion process. Most commonly, workpieces are welded by melting both of them and adding more molten metal or plastic to form a pool that cools to form a stron, where even higher temperatures are used, the base material melts and the filler material (if used at all) has the same composition as the base material.

The "welding" of cast ironCast iron is a group of metals based on the three elements Iron, Carbon and Silicon. It is made by remelting pig iron, often along with substantial quantities of scrap iron, and taking various steps to remove undesirable contaminants such as phosphorus an is usually a brazing operation, with a filler rod made chiefly of nickelThis article is about the element nickel. See also nickel (U. coin) and nickel (Canadian coin). Nickel is a metallic chemical element in the periodic table that has the symbol Ni and atomic number 28. Notable characteristics Nickel is silvery white metal being used although true welding with cast iron rods is also available.
