In various burners, the oxidizing flame is the flame produced with an excessive amount of oxygen. When the amount of oxygen increases, the flame shortens, its color darkens, and it hisses and roars. ... The reducing flame is the flame with low oxygen.

What is a oxidizing flame used for?
Oxidizing Flame:
The outer flame has blue in color. This flame is used to weld oxygen free copper alloy like brass, bronze etc. This is all about types of flames used in welding.
What is the difference between oxidising Carburising and neutral flames?
A neutral flame is named neutral since in most cases will have no chemical effect on the metal being welded. A carburizing flame will produce iron carbide, causing a chemical change in steel and iron. ... An oxidizing flame is hotter than a neutral flame and is often used on copper and zinc.
What does an oxidizing flame look like?
An oxidizing flame is any flame that has an excess of oxygen present. A hissing noise, sharp candles, and a paler blue color easily identify the flame. This flame is cooler than a neutral flame because there is an excess of oxygen flowing though the combusting gasses.
What is reducing zone in welding?
Welding: When burned in oxygen, acetylene produces a reducing zone, which easily cleans the metal surface.
Which flame is used for cutting?
The neutral flame is the flame most generally used when welding or cutting. The welder uses the neutral flame as the starting point for all other flame adjustments because it is so easily defined.
What produces the hottest flame?
In principle, the combustion of hydrogen with fluorine produces the hottest flame (Tf 4300K).
Why is reducing flame so called?
The reducing flame is the flame with low oxygen. It has a yellow or yellowish color due to carbon or hydrocarbons which bind with (or reduce) the oxygen contained in the materials processed with the flame. The reducing flame is also called the carburizing flame, since it tends to introduce carbon into the molten metal.
When you turn the torch off which gas do you always turn off first?
If you shut the torch off by shutting down the oxygen valve first and then the fuel valve, if there is any issue with the fuel valve leaking, there will be a small flame left burning.
What is the application of carburizing flame?
A carburizing flame is used in hardfacing and similar processes to obtain fusion between base metal and weld metal without deep melting of the base metal. See also Reducing Flame, Oxidizing Flame, Neutral Flame, and Oxyfuel Gas Welding.
What is the difference between a harsh flame and a quiet flame?
What is the difference between a harsh flame and a quiet flame? A harsh flame is produced by using too much pressure of both gases to the tip, and it is noisy; a quiet flame has the correct amount of pressure and it does not make any noise.
What does oxidizing mean?
verb (used with object), ox·i·dized, ox·i·diz·ing. to convert (an element) into an oxide; combine with oxygen. to cover with a coating of oxide or rust. to take away hydrogen, as by the action of oxygen; add oxygen or any nonmetal.
Which flame is used for preheating?
Flame Cutting/Oxygen Burning requires some source of intense heat to get the plate hot enough to be cut/burned. This source of heat is referred to as the “preheat flame”.
