Acetylene is traditionally generated through a chemical process using Calcium-carbide and water. It is used mainly for industrial applications and in the laboratories as high Purity.
Acetylene is the only fuel gas to cover all industrial oxy-fuel application due to its high performance and other physical properties. Its combustion in pure oxygen produces the highest achievable flame temperature, over 3300°C, releasing 11,800 J/g, allowing it to be used in welding, cutting, brazing, and soldering metals.
