What is the temperature of a neutral flame with an oxy-acetylene torch?

The temperature of a neutral flame produced by an oxy-acetylene torch is approximately 5600°F. A neutral flame is characterized by a balanced ratio of oxygen to acetylene, which allows for complete combustion. This flame type achieves the highest temperature among the different flame types generated by an oxy-acetylene torch, making it particularly suited for welding processes where precise temperature control is critical.

In welding applications, the neutral flame is favored because it does not produce oxidizing or carburizing effects on the metal, allowing for clean and effective welding. Understanding the specific temperature associated with a neutral flame helps welders select the appropriate settings for various materials and situations, ensuring quality results and minimizing oxidation during welding.
