Can you melt silver with an oxygen and propane torch?
only propane, it won’t generate as much heat as a propane and oxygen torch. If you are only soldering small bits of silver, your torch may be hot enough for you to melt silver solders. However, remembering that silver is a highly heat conducting metal, it will be sucking away your torch heat as you work. For this reason, you will
Can you burn gold with a torch?
Try using a propane torch to melt gold. As noted before, you must be extremely careful about safety concerns if you are going to use a torch. However, a torch will melt gold within a few minutes. The gold should be placed into a crucible. Then, put the crucible on a fireproof surface, and direct a torch toward the gold within the crucible.

What kind of torch do you use to braze copper?
Oxy acetylene torches burn very hot and could easily burn through most copper and brass piping so using this type of torch requires greater skill than propane, acetylene, MAPP gas or other fuel types. This technique can be used to repair cast iron drain pipes where the high heat is required.
Can you braze with a Bernzomatic torch?
Use the right brazing rod material for the metal used in your project. The brazing rod should be melted by the heat of the metal pieces being joined, not by direct contact with the flame of the torch. Use a torch that produces a high intensity flame.
Can propane gas be used for brazing?
Oxy Propane Oxygen and Propane fuelled kits are however, ideal for Silver Solder, Brazing, Cutting and Heating. So as long as you don't want to Weld, Oxygen and Propane is a great way to go!
Can you use MAPP gas to braze?
The problem with the larger, cooler flame common to standard air-Mapp gas rigs is: Not only is it limited to brazing smaller components and smaller copper tube sizes, but it takes longer and results in more heating of the surrounding area, which does more damage to heat-sensitive parts.
What is the best gas to braze copper with?
Braze-A-Gas consists of oxygen and acetylene that, when combined, are the engineer's best choice for brazing copper tubes together in refrigeration and air-conditioning systems. These products produce a flame temperature of about 3 500°C, which is significantly hotter than propane, propylene, or MAPP gas.
Which torch is best for brazing?
If you're in the market for the all-around best torch for brazing and soldering, the Bernzomatic Torch is our recommendation.
Is MAPP gas hotter than propane?
MAP-Pro gas burns at a temperature of 3,730 degrees Fahrenheit, while propane burns at 3,600 F. Because it heats copper faster and to a higher temperature, MAP-Pro gas is a superior alternative to propane for soldering.
Can brazing be done without oxygen?
Torch brazing of copper can be done without the use of flux if it is brazed with a torch using oxygen and hydrogen gas, rather than oxygen and other flammable gases. Machine torch brazing is commonly used where a repetitive braze operation is being carried out.
What temperature do you need to braze?
Most brazing processes run at temperatures between 800°F and 2,000°F. For a strongest braze joint, the metals that are being joined together need to be at close to the same temperature.
Can I braze with a blowtorch?
Blowtorches are Primarily Designed for Cutting Metal, not Welding. Blowtorches were designed for cutting metal, rather than binding it together. Blowtorches can still be used in some braze welding and soldering applications.
What is brazing?
Brazing is a heat-sensitive bonding process where a filler metal can be used to join two metals together.
Why would you want to braze copper?
Brazing copper is how you can connect copper pipes, typically for plumbing. You would need to be a licensed plumber to use this method, though, and the opportunity to braze a pipe usually doesn’t come up.
Do you need flux to braze copper?
To braze copper, you need flux just so that solder can run freely and is heated by the torch. The rod is then pushed into place without being forced, which would mix up the heat bath and create an unreliable connection between two pieces of copper.
How to braze copper
Brazing is done by heating the copper, then running a layer of constantan (a type of metal with high thermal conductivity and low electrical resistivity) on top. If you line up the two pieces correctly, they will fuse when heated to 250°C.
How to avoid any potential problems when brazing
It’s worth looking for any signs of leaks – tiny beads of molten metal and smoke. If you see them, quickly cover the hole with a wet rag or baking soda to prevent sparks from igniting the gas; then add some more flux (if your rope brazing process includes it) and continue brazing.
Can copper and stainless steel be welded together?
Yes, copper and stainless steel can be welded together. This type of welding is known as brazing, and it’s how the copper plumber joins the pipes in the plumbing system. Brazing uses a filler metal that melts at a much lower temperature (about 700 degrees F/356 degrees C) than ordinary welding does (between 2,000-2,700 degrees F).
What torch do you use to melt silver solder?

What is soldering copper?
Soldering also has two other important aspects that can be advantageous depending on what you’re doing: 1 Because of lower temperatures than brazing, soldering does not oxidize the inside of a copper pipe and therefore you don’t need to purge your pipe with nitrogen when you’re soldering. 2 Although the higher temperatures involved with brazing create stronger joints, the higher temperatures also weaken the structural integrity of the copper pipe itself and make it more prone to breaks caused by bends or strong vibrations.
What does it mean to braze and solder HVAC?
Brazing and soldering are some of the most common things you’ll do in HVAC. Doing it right means you’ll have a system that works; that stands up to the challenge of pressure and temperature. Doing it wrong means your joints will fail and so will the system they’re tied to.
What kind of torch do you need to solder?
In terms of torches, there are two main types: the cheap kind and the more expensive kind. The cheap kind is a MAPP gas or propane torch that uses a one-time-use 14-ounce tank you can buy at any hardware store, and is also referred to as a turbo torch.
What torch to use for brazing copper pipe?
Because brazing involves higher temperatures than soldering, using an oxygen-acetylene torch is your surest bet because this gets hotter than a MAPP gas or propane torch, although for most small-to-medium jobs (thinner copper piping) a turbo torch should also work. Also remember that MAPP gas burns hotter than propane.
What is brazing rod?
For joining copper lines we usually use brazing rods that are made out of a copper-phosphorous combination. With six percent silver, this type of brazing rod starts to melt at 1,190 °C.
When did brazing and soldering start?
You could say that brazing and soldering are literally what brought us out of the Stone Age 5,000 years ago when man started to develop metal tools and weapons. When you braze and solder, you’re joining the proud ranks of those who’ve come before you to practice the science and art of combining metal with metal.
How are two metals joined?
In this process two metals are joined by melting them together. Of these three methods welding involves the hottest temperatures and welded joints are the strongest. Keep this in mind as you move from soldering to brazing to welding: as the heat required for melting increases the strength of the joint also increases.
