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.
It is called Brazing rods or lead free solder
brazing is joining of two metals by using filler metals.to melts the filler rods only which temperature is above the melting point (>450c).initially flux metal is used to avoid the oxidation ....this process is very strongly than soldering method ...weaker than welding method..
Brazing rods are typically made from a variety of metal alloys, most commonly composed of copper, silver, and zinc. The specific composition can vary depending on the application, but these materials are chosen for their ability to create strong joints at high temperatures without melting the base metals. Some brazing rods may also include additives like phosphorus to enhance flow and bonding properties.
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
Brazing for hobbies
The best techniques for achieving strong and durable joints when brass brazing include proper cleaning of the surfaces to be joined, using the right flux and filler metal, applying the correct amount of heat, and ensuring a tight fit between the parts. Additionally, controlling the brazing process to prevent overheating and using a suitable brazing technique can help create strong and long-lasting joints.
You should use solder, not brazing. Brazing is used to join iron or steel products together.

Primarily when brazing cast iron. Nickel rods are available to arc weld cast iron but in most cases it has to be preheated and it takes experience to prevent cracking. Using oxy-acet provides a means to preheat, maintain the temperature, and braze. Welding, brazing, and silver soldering with oxy-acet have become lost arts. Most common metals can be welded with this process including steel and aluminum.
Brazing spelter is a term used to refer to a type of filler metal used in the brazing process, which involves joining metals together at elevated temperatures without melting the base materials. Typically made from alloys containing zinc, copper, or other metals, brazing spelter is applied in a molten state to fill the gaps between the workpieces. Once cooled, it creates a strong bond that is capable of withstanding significant stress. It's commonly used in applications like plumbing, HVAC, and metalworking.
They are used for repairing things made of aluminum. What is needed is a heat source from gas such as propane gas, mapp gas or oxy-acetylene gas. This method makes for stronger welds than conventional Tig welding. It works on aluminum and cast aluminum, pot metal, copper, magnesium and white or porous metals. One of the main benefits of using aluminum arc brazing is that it can be used to weld and repair metal structures and things that are difficult to work on with more conventional welding methods. This includes corroded parts and also areas that have come in contact with oil and fat that make the area difficult to work on using the older methods of aluminum welding rods. The weld produced is stronger and the work quicker using aluminum arc brazing.
