MetallAktivgasSchweißen

MetallAktivgas is a term sometimes used in industrial contexts, particularly in welding and metal processing, to refer to active gases used in arc welding. These gases, unlike inert gases, participate in the welding process by reacting with the molten metal. Common examples of gases classified as active in this context include carbon dioxide (CO2) and oxygen (O2), often used in mixtures with other gases like argon. These active components can influence the arc stability, weld pool fluidity, and the metallurgical properties of the deposited weld metal. For instance, oxygen can help reduce surface tension in the weld pool, improving wetting and penetration, but excessive amounts can lead to oxidation and porosity. Carbon dioxide, when used in MIG (Metal Inert Gas) or MAG (Metal Active Gas) welding, also contributes to arc characteristics and can form oxides. The specific choice and concentration of active gases are critical for achieving desired weld quality and are tailored to the base metal being welded and the specific welding application. Understanding the role of these active gases is essential for optimizing welding parameters and achieving sound welds.
