Flux cleans the metal and helps the solder stick.
Brazing
Put simple a metal that doesn't have iron in it,metal that if u put a magnet to it won't stick.
It would stick to the magnet....
both are attracted to each other from the metals inside of them
In welding, the parent metal, that is the pieces to be joined are actually melted along with the filler metal, if any. The filler metal is the same material as the parent metal. In brazing, the pieces to be joined are heated, but do not melt. Only the filler metal is melted. The filler is a brazing alloy, usually an alloy containing brass, silver, or other metals. The filler metal is not the same as the parent metal. Since brazing does not melt the parent metal, less heat is required, but the resulting joint is not as strong as a welded joint. The brazing alloy is usually a different color than the parent metal, so the joint will stand out and be visible, which can be an issue where appearance is important.
Soldering and brazing both join two parts by melting a different metal as an adhesive without damaging the two parts being joined. Soldering uses a different metal that has a lower melting point (usually lead-based) than the metal used in brazing (usually silver). This allows easier joining in soldering, but a stronger bond in brazing.
If the hole is very small the material you are brazing with should fill it. A small piece sheet metal can be brazed in place to cover larger holes.
Yes, that is proper technique.
Flux can be applied using brazing rods. Bronze and Steel weldings can also be applied using brazing rods. You can also apply iron and other types of metal.
You use an acetylene torch and special brazing rods.

You must use flux while brazing because the flux prevents oxides from forming while the metal is heated. The flux also serves the purpose of cleaning any contamination left on the brazing surfaces.
Welding would melt the base metal and filler metal while brazzing only melts the filler metal.
You may mean soldering, brazing or welding. These are all methods of joining metals
