Oxy-Acetylene. A mixture of oxygen and acetylene.
Commerically it is still acetylene, however, its chemical name is 'ethyne'. Its structure is 'H-C///C-H'.
NB The symbol '///' repreent a triple bond between the two carbons.

How hot is gas flame when welding?
When the fuel is used with oxygen, flame temperatures can range from 4500 to 5600 degrees Fahrenheit, depending on the fuel used. (2500 - 3100 degrees Celsius)
Which gas welding flame is the hottest?
It's called a Neutral flame. Enough Oxygen is added to the fuel to allow almost complete combustion. The remaing fuel is combined with the surrounding air and burned. This is the best flame for most cutting and welding operations. Too little Oxygen produces a Carburizing flame. It is yellow and produces smoke. A slightly Carburizing flame is used when welding Aluminum. Too much Oxygen produces an Oxidizing flame. It begins to sound louder and the inner flame comes to a point.
What is the gas for welding?
Oxygen and acetylene for flame welding. Argon for Tig welding CO2 for MIG welding steels Argon for MIG welding aluminum TRI-mix for robotic mig of steels. And helium is added for some overhead welding.
What types of flame are obtained in oxy-acetylene gas welding?
When the correct amount of Oxygen is mixed with the Acetylene a NEUTRAL flame is produced. Less than that amount produces a CARBURIZING flame. Too much Oxygen creates an OXIDIZING flame. Most welding/cutting is done with a NEUTRAL flame but all flame adjustments have their purpose.
Why for welding use oxygen and acetylene?
Because of all the gas combinations used with this process Oxygen and Acetylene, in correct proportions, produce the highest flame temperature.
What is the most commonly shielding gas for GMAW?
Argon is the most common gas used in gas metal arc welding.
How hot is gas flame when welding?
When the fuel is used with oxygen, flame temperatures can range from 4500 to 5600 degrees Fahrenheit, depending on the fuel used. (2500 - 3100 degrees Celsius)
What kind of flame is more economical?
Methane (natural gas) is the most commonly used gas for residential heating. In rural areas where there are no pipes carrying natural gas and in recreational vehicles, propane and butane are commonly used.
What are the enviornments of welding?
The environments of welding could be one of the following:- open air- outer space- under waterthese different environments need different energy sources like gas flame, an electric arc, gas flame or laser.
What gas is used in welding cylinders?
Welding cylinders contains different types of gas. Oxygen is common to all the kinds of cwelding. The other common gas used is a combustible gas like acetylene which is the fuel for the torch. The fuel gas could also be hydrogen, MPS or MAPP gas, butane, propane, or propylene. Some welding (e.g. aluminum welding) requires a shield gas which protects the surfaces near the flame and improves the quality of the weld. These can include helium, argon, carbon dioxide or nitrogen.

What type of inert gas is used for the spray method of welding?
== == 95% Argon 5% CO2 is most commonly used for spray MIG.
Which gas is use in gas welding?
oxygen and acetylene gas Argon gas is used in MIG and TIG welding
Which gas burns the hottest when cutting torch is used?
oxygen supports the combustion of the gas that one uses in the welding/cutting torch. Acetylene combined with Oxygen produces the hottest flame.
What does argon gas do to a flame?
Argon gas cannot react with most substances, and can extinguish a flame if it displaces enough of the oxygen around the burning material. Argon is used as an inert gas in electric arc welding to prevent oxygen from reacting with the heated materials, such as aluminum and titanium.
What types of flame are obtained in oxy-acetylene gas welding?
When the correct amount of Oxygen is mixed with the Acetylene a NEUTRAL flame is produced. Less than that amount produces a CARBURIZING flame. Too much Oxygen creates an OXIDIZING flame. Most welding/cutting is done with a NEUTRAL flame but all flame adjustments have their purpose.
