A cutting flame with excess oxygen is known as an oxidizing flame. It is commonly used in metal cutting processes, as the higher oxygen concentration facilitates faster and more efficient cutting by promoting the oxidation of the metal. However, care must be taken to prevent overheating or damaging the material being cut.

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.
What colour flame would indicate ethane burning in excess oxygen?
A blue flame would indicate ethane burning in excess oxygen. Blue flames are typically associated with complete combustion and sufficient oxygen supply during the burning process.
What causes a burner flame to be smoky and to separate from the tip of the burner?
A smoky burner flame that separates from the tip of the burner is typically caused by an incorrect air-to-fuel ratio. This can be due to a clogged burner or inadequate airflow. It can also be caused by a lack of proper maintenance or adjustment of the burner.
What is the flame that is used for cutting and welding of metals?
The flame used for cutting and welding of metals is typically a combination of oxygen and a fuel gas, such as acetylene or propane. This flame produces high temperatures that can melt and join metal pieces together or cut through metal with precision.
What alkynes produces the hottest flame when burned in oxygen and is primarily used as a fuel gas?
Acetylene (C2H2) produces the hottest flame when burned in oxygen. It is primarily used as a fuel gas for welding and cutting metal due to its high flame temperature.

How many layers does the flame have?
The hottest flame has an excess of oxygen and has two zones or cones. A lower-temperature flame, meanwhile, has three zones.
What colour flame would indicate ethane burning in excess oxygen?
A blue flame would indicate ethane burning in excess oxygen. Blue flames are typically associated with complete combustion and sufficient oxygen supply during the burning process.
Does flame cutting use a neutral flame or slightly oxidizing flame?
Assuming that you are using the Oxygen-Acetylene cutting process; both, depending at what stage/phase of the cutting process you are in. What we encounter is a gas flow differential problem. With the cutting torch flame properly adjusted (the acetylene valve opened to the point where the un-mixed acetylene flame is burning without producing any smoke but still in contact with the cutting tip of the torch, the oxygen valve is slowly opened until you have adjusted the flame to a neutral quality or setting. Press the cutting oxygen lever; typically the flame will become slightly carburizing ("feathers" will appear at the ends of the pre-heat flames) this phenomonom occurs because of the drop in line pressure due to the high flow of oxygen through the cutting tube or orifice. With the oxygen lever remaining depressed, readjust the flame to a neutral setting. This will cause the flame to become slightly oxidizing when the cutting lever is released; since an oxidizing flame burns slightly hotter than a neutral flame the pre-heat of the metal that is being cut is faster. When the metal is at the proper pre-heat or kindling temperature (1600 F for pure iron - various steel alloys will be slightly different; beginning to turn bright red is a good indicator) depress the cutting oxygen lever, the flame will revert to "neutral" and the cut can then begin. Weld. Prof.
What gas to use for plasma cutting?
Oxygen and acetylene. A cutting head for an oxy-acetelyne torch has a trigger with greatly increases the oxygen in the mixture when activated. To cut, the excess oxygen in the flame basically burns the metal away.
What kind of flame is non luminous?
No-luminous flames, with a blue color, are formed when the oxygen is in excess.
What causes a burner flame to be smoky and to separate from the tip of the burner?
A smoky burner flame that separates from the tip of the burner is typically caused by an incorrect air-to-fuel ratio. This can be due to a clogged burner or inadequate airflow. It can also be caused by a lack of proper maintenance or adjustment of the burner.
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.
Describe burning as a reaction with oxygen?
Oxygen itself is non flammable but it readily supports combustion and the more oxygen that is added, the hotter the flame will be. An easy way to verify this is to check with a welder. When he turns the oxygen only on he gets no flame. If he turns on the acetelene only he will get a flame but not hot enough to be useful. When he adds oxygen to the flame it will get hot enough to make a cutting torch that will cut through layered steel.
