An oxidizing flame is used in Braze welding. Not to be confused with Brazing, Braze welding uses bronze filler rod in a similar manner to fusion 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 is oxidizing flame desirable in welding of copper alloys?
because a thin-protective layer of slag is formed over the molten metal
Why the charcoal burns without giving a flame?
What you call a flame is vaporized fuel oxidizing. Vaporizing pure carbon, which is what charcoal (theoretically) is requires temperatures higher than anything you're likely to achieve.
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.
Which type of flame will you use for heating?
the blue flame
Flame Outer oxidizing zone?
The outer oxidizing zone of a flame is the layer which gets into direct contact with oxygen. Lesser oxygen produces a yellow flame, but more oxygen supply produces a blue flame.
Describe the oxidizing and reducing region of the Bunsen flame?
well, u juz need to use yah head somtyms buddy,, :p
What is the temperature of the oxidizing oxygen LP gas flame?
896 degrees fahrenheit to 1121 degrees fahrenheit
Sketch and label of different flame region coming from Bunsen burner?
The flame has an # outer oxidizing zone # middle reducing zone # inner unburned gases
How many regions should a well-adjusted burner flame have?
It will have an oxidizing region and a region where gas and air mix.

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.

What type of a flame is best to use?
if you are talking about what flame to use on a Bunsen burner than the yellow flame is to make sure that everyone knows that there is a flame but the blue flame (less visible) is used as the hotter flame and the better one.
