What is a brazing hearth used for?
brazing clints head
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.
Is spelter magnetic?
No, spelter is not magnetic. Spelter is simply a synonym for zinc and is similar to copper or brass as well.
Can you braze copper to copper or are the melting temperatures of copper and brazing spelter too close to each other?
Copper melts 1981 deg F Brazing alloys flow @ 900 -1,200 BTU all one has t do is pay attention to the flux if applicable
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.
What is hobby brazing?
Brazing for hobbies
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 a brazing hearth used for?
brazing clints head
What is another name for brazing?
Brazing is also known as soldering or soft soldering in the layman vernacular.
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.
How do you do zinc welding?
Brazing
What can be applied using brazing rods?
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.
