Exploring the oxy acetylene temp reveals one of the hottest flame temperatures achievable in common industrial processes. This article clarifies the real meaning of oxy acetylene temperature, highlights why it matters for welders and fabricators, and explains how acetylene behaves both with and without oxygen. Gaining a solid understanding of these temperatures helps ensure safety, precision, and the best possible results for anyone working with welding, pressure vessel manufacturing, or ASME-certified equipment. Additional background can be found on our About Us page or by reading more on oxy-fuel welding.
In welding and cutting, oxy‑acetylene refers to the process of mixing pure oxygen and acetylene gas. The pairing allows for exceptionally high flame temperatures. Acetylene, a hydrocarbon, reaches temperatures above 3,100 °C (5,600 °F) when burned with oxygen, making it the hottest commonly used fuel‑gas flame. For more technical data, see the Engineering Toolbox’s guide to flame temperatures.
The temperature produced by burning acetylene varies significantly based on the oxygen supply.
With Oxygen: Flames can reach roughly 3,200–3,500 °C (5,800–6,300 °F), especially at the peak temperature of the inner cone during welding. Both Wikipedia and the Engineering Toolbox confirm acetylene‑oxygen flames may go as high as 3,480 °C.
Without Oxygen: In the absence of extra oxygen, acetylene burns at a much lower temperature. The resulting flame is inefficient, produces more soot, and is not suitable for industrial applications.
A hotter flame allows welders to cut and join metals more quickly and cleanly. Consistent oxy acetylene temp is crucial for controlling weld pools, especially when handling tasks like pressure vessel fabrication and repairs. Following precise temperature control ensures weld integrity and compliance with industry codes.
Welders adjust oxygen and acetylene ratios to create several distinct flame types:
Neutral Flame: Combining equal parts of oxygen and acetylene, the inner cone temperature reaches approximately 3,200–3,300 °C. Clean combustion and stable results make this the preferred choice for most welding projects (see more on Wikipedia).
Carburizing (Reducing) Flame: By increasing acetylene, the flame becomes cooler and shows a distinctive “acetylene feather.” Professionals often select this setting for tasks that benefit from a softer or carbon-enriching atmosphere (details at MEWelding).
Oxidizing Flame: Boosting the oxygen ratio produces a hotter, sharper flame with a pointed inner cone. This type can damage some steels but works well for materials like brass or bronze. The team at Red River always chooses the right flame type to match the job, as outlined in our fabrication services page.
Safety must always come first. Cylinders should remain secured and upright to prevent accidents. Using flashback arrestors and ensuring proper ventilation can greatly reduce risks. Workers are encouraged to wear certified eye protection and follow official OSHA guidelines along with procedures described on Wikipedia

The inner cone of a neutral flame reaches about 3,200–3,300 °C, with peak temperatures sometimes exceeding 3,500 °C (About Us, Process of Pressure Vessel Manufacturing, ASME Pressure Vessel, Wikipedia).
Oxy‑acetylene flames are much hotter—ranging from 3,100–3,500 °C. By contrast, propane/oxygen flames reach only about 2,800 °C (Wikipedia, ThoughtCo Flame Temperatures).
A neutral flame, with equal parts oxygen and acetylene, provides balanced combustion. This is the safest and most efficient choice for welding steel (Wikipedia, MEWelding.com).
Pure oxygen eliminates nitrogen dilution. This creates a more complete combustion process and achieves higher flame temperatures, which is essential for welding and cutting tasks (Wikipedia, Biology Insights).
Burning acetylene without extra oxygen produces a cooler, less stable flame. This incomplete combustion can result in excessive soot and dangerous byproducts.
Key safety features include flashback arrestors, adequate ventilation, secured cylinders, and use of protective gear.
We use our expertise with flame temperatures in pressure vessel fabrication and ASME vessel manufacturing to guarantee top welding integrity and full code compliance for every project.
