brazing clints head
It is often used in fabricating structures out of aluminum. Antennas and machinery enclosures are examples I am personally familiar with. Aluminum is tough to braze any other way, because you have little latitude with temperature. The brazing alloys that work with aluminum start to flow at temperatures that are very close to destructive for aluminum, especially in the presence of atmospheric O2. Temperature in dip brazing can be very tightly controlled.
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.
The type of material used to connect the pieces. Solder is used on copper or brass. Brazing uses a copper alloy and is used on Iron based items. Same process in how it is done.
Brazing is actually not a method of welding as it does not melt the joint metal together. Brazing is actually much closer to soldering. It is a process that (usually) uses a gas torch and a thin brass rod to bind two (or more) pieces of metal together. The torch heats the joints surface to the melting temperature of brass at which time the brass filler rod is melted into the joint to fuse them together.

You should use solder, not brazing. Brazing is used to join iron or steel products together.

Yes, that is proper technique.
Brazing for hobbies
A brazing torch is used to head up metals to a high temperature. This is helpful for welding, molding and construction which uses metals. It can be hand held for a torch.
Gas welding/soldering/brazing
When Brazing copper to copper flux is normally not needed When brazing steel or copper based alloys then the flux is used to help the wetting action (Better flow of the brazing alloy) and to prevent oxidation A typical rod would be Union Carbide 25 M or check out the AWS booklet
The solid bench like piece of equipment that has robust sides is a brazing hearth. The sides act as heat shields and the hearth has a compressor. It is used to join steel together.
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.
The compound, magnesium fluoride, is used in the process of brazing. It helps to smooth out the air particles by using this chemical compound to get rid of the pollutants, which helps with preventing oxide formation.
Brazing is also known as soldering or soft soldering in the layman vernacular.
