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.

Filler what can you use for brazing holes in sheet metal?
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.
Definition of soldering and brazing?
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.
What is the Applications of dip brazing prosses?
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.
Your consultants are asking you to pass nitrogen through copper pipes while brazing to prevent oxidation inside the pipes. These pipes are for refrigerant. Is this a regular practice?
AnswerPumping nitrogen through refrigerant piping during brazing is an excellent practice. The reason is that nitrogen helps to prevent the buildup of oxide scale on the inside of the pipes during the brazing process. Refrigerant is a natural cleaning agent, and as it is being pumped through the pipes it will pick up the scale and contaminate the refrigerant. It is possible that this will damage to the compressor.
What is the melting temperature of brazing spelter?
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.
Can you braze copper to copper or are the melting temperatures of copper and brazing spelter too close to each other?
Yes, copper can be brazed to copper. The melting temperatures of copper and brazing spelter are different enough to allow for successful brazing. Brazing temperatures are typically lower than the melting point of copper, allowing for a strong joint to be created between the two copper pieces.
Is spelter magnetic?
No, spelter is not magnetic. Spelter is simply a synonym for zinc and is similar to copper or brass as well.
What two metals make up Spelter?
Composition of Spelter is - Copper- 90%, Zinc- 10%
what is the meling point of spelter?
Spelter, sometimes known as zinc, is used to fuse metals with a higher melting point. The actual melting point of spelter is 787.15 degrees Fahrenheit.

Which brazing rod do you use when brazing copper to brass?
You should use solder, not brazing. Brazing is used to join iron or steel products together.

What is another name for brazing?
Brazing is also known as soldering or soft soldering in the layman vernacular.
Can brazing stick to metal?
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.
Are soldering and brazing fluxes the same?
No, soldering and brazing fluxes are not the same. Soldering fluxes are designed to remove oxides from the metal surfaces being joined during soldering, while brazing fluxes are formulated to clean the joint and promote wetting for the filler metal in brazing processes. Additionally, brazing fluxes can handle higher temperatures compared to soldering fluxes.
Why must you preheat copper before brazing?
You usually do not braze copper, you solder it. If you were to use brazing rod on copper, the copper would have very close to the same melting point as the brazing rod. This makes it difficult to do. As far as preheating the copper, it needs to be hot enough for the brazing to flow.
