Brazing typically requires temperatures between 450°C (842°F) and 1,100°C (2,012°F), depending on the materials being joined and the type of filler metal used. The process involves melting a filler metal that has a lower melting point than the workpieces but is heated above its melting point to create a strong bond. Proper temperature control is crucial to ensure effective joining without damaging the base materials.
Common gases used in brazing include acetylene, propane, natural gas, and hydrogen. These gases are typically used in combination with oxygen to produce a flame with the appropriate temperature for brazing different materials.
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.
A suitable source of heat for brazing is typically a torch fueled by a gas such as acetylene, propane, or natural gas. This type of torch provides a high enough temperature to melt the brazing material without melting the base metals being joined.
Brazing for hobbies
You should use solder, not brazing. Brazing is used to join iron or steel products together.

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.
Brass and bronze brazing alloys typically melt at temperatures from 1500 degrees F to 2000 degrees F. Silver brazing alloys melt at temperatures as low as 1145 degrees F. Nickel silver brazing alloys melt at temperatures around 1200 degrees F, but can be worked up to 1750 degrees F.
Extraction is crucial in the brazing hearth because it removes harmful fumes, smoke, and gases generated during the brazing process, ensuring a safe working environment for operators. Effective extraction also helps maintain the quality of the brazed joints by preventing contamination from airborne particles. Additionally, proper ventilation aids in temperature control, which is essential for achieving optimal brazing results. Overall, extraction systems contribute to both safety and product integrity in brazing operations.
Brazing is also known as soldering or soft soldering in the layman vernacular.
Yes, brazing can stick to metal by creating a strong bond between the brazing material and the metal surface through the application of heat. Brazing relies on capillary action to securely join two or more metal pieces together.
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.
