Can you braze with oxy acetylene?
The Braze-A-Gas® range of oxy-acetylene gases from A-Gas meets the demands of high temperature jobs by delivering around 3500°C. They can also be used with a range of metals including copper and steel. High temperature oxy-acetylene gases are very flexible. This means you get more efficient brazing and less heat waste.
What pressure should oxygen and acetylene be set at for brazing copper?
14-15 psi
Brazing with air/ acetylene torches is a popular alternative to oxygen mixed fuel gas. The fuel gas flow aspirates air into a mixer that contains an internal vane that spins the gas to improve combustion and increase flame temperature. If the tank has a delivery pressure gauge set the delivery pressure at 14-15 psi.
Is Mapp gas hot enough for brazing?
Is Mapp gas hot enough to braze? Genuine MAPP gas can be used in combination with oxygen for heating, soldering, brazing and even welding because of its high flame temperature of 2925 °C (5300 °F) in oxygen. Hard soldering (silver soldering) requires temperatures of about 1200 to 1400 degrees F.
Why is my torch popping?
Overheated Nozzle If the popping is only happening after you’ve been using the torch for a while, like maybe after half an hour or so, it might be because the nozzle is getting too hot. Then dunk the nozzle in water. This will instantly cool it down, and water won’t go inside your torch.
Why is acetylene used as welding gas?
Acetylene is used as fuel for oxy-cutting and oxy-welding . When mixed with oxygen, it’s the most effective gas to form a flame hot enough to cut and weld most metals with ease. It’s more expensive than some other fuel types, but it’s the best type of fuel to use.
Can you use a propane torch for brazing?
Brazing with Propane. Here is the answer to whether you can braze with a propane / air torch. You can but you have to control the environment so that the heat loss to the atmosphere and parts is lower than the heat being put into the braze joint.
Why to use acetylene for welding?
Oxy acetylene welding can be used if quickly joining metals together is your only concern because the weld seam formed is not as neat as the ones created by other welding methods. A neutral flame is also used for welding using a cutting torch, but you need to move your torch in a circular manner so that the metals will melt and pool towards the small gap present between them.
Do I need to use acetylene for soldering?
For soldering, air/acetylene systems are preferred . The flame characteristics allow lower heat input and reduce the risk of overheating solder and flux. Flame characteristics and brazing. The fact that an oxygen/acetylene flame has a higher temperature has already been mentioned.
