Oxygen-acetylene gas welding was first developed and used in 1903 by the French Engineers Edmond Fouche and Charles Picard. Pure oxygen was used instead of ordinary air to increase the flame temperature.

WitrynaImportance of Purity of Acetylene. Acetylene can react with oxygen or impurities causing massive explosions. Hence, the production process should be flawless. During the production process, if the acetylene is not completely pure, the resultant product could change dramatically. Maintaining the purity of the acetylene produced is vital. WitrynaThere are three basic types of gas welding flame: Neutral: balanced. Carburizing: excess acetylene. Oxidizing: excess oxygen. The types of flame are named based on the chemical effect on the material being welded. For example, an oxidizing flame produces oxidation while a carburizing flame produces iron carbide.
