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)
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.
The Oxy-acetylene flame is much hotter and the preferred combination for the welder especially when welding pipe and plate metal. Somewhat of a rare welding procedure in modern times. Replaced by arc welding. Liquid Propane Gas burns cooler and is preferred by employers as it is cheaper. Not bad results on light gauge material, again takes longer to heat up. -RedSeal Welder
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.
Oxygen is used in welding to increase the burn rate of the fuel gas, such as acetylene, in the oxy-fuel welding process. The oxygen reacts with the fuel gas, creating a high-temperature flame that is used to melt and join metal together. Additionally, oxygen is used in oxy-fuel cutting to aid in the combustion process, resulting in a clean cut through metal.
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.
Welding involves melting metal. Wood flames don't get hot enough.

An oxyacetylene flame is a type of hot, precise flame created by combining oxygen and acetylene gases in a welding torch. This flame is commonly used in metal cutting, welding, and brazing applications due to its high temperature and ability to produce a concentrated heat source.

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.
ARC welding uses large amounts of electricity to melt the metal, not a hot flame. So no, LPG cannot be used for ARC welding.

Oxy-fuel welding is a welding process that requires O2 gas. It uses oxygen and a fuel gas, such as acetylene, to create a high-temperature flame for the welding process. The oxygen supports combustion and helps create the heat needed to weld the materials together.
It causes too much oxidation, and it doesn't burn hot enough to weld with anyway. You can braze non-ferrous metals with it; some jewelers like it because you can hook up to the natural gas line coming into the building and go for it.
To gas weld, you'll need a gas welding torch that mixes fuel gas with oxygen to create a flame. The workpiece is heated with the flame until it reaches the melting point, and a filler rod is added to create a bond between the two pieces. Practice and proper safety equipment are essential for successful gas welding.
