What is the flame temperature when using an oxidizing flame with oxy-acetylene?

The flame temperature when using an oxidizing flame with oxy-acetylene is approximately 6300°F. An oxidizing flame occurs when there is an excess of oxygen in the flame mixture, which allows for a higher combustion temperature compared to other flame types, such as a neutral or carburizing flame. This increased temperature is ideal for welding certain metals that require high heat input to ensure proper fusion and penetration.

In oxy-acetylene welding, the adjusting ratio of acetylene to oxygen can significantly impact the flame characteristics, and the most precise operations often occur within the oxidizing range because of its ability to achieve these elevated temperatures. Knowing this helps welders choose the right flame type for their specific processes, ensuring efficient and effective welding results.
