Shielding gas, welding gas
Depending on the melting behavior of the electrode from which the arc burns to the workpiece, a distinction is made between two main groups of gas-shielded welding processes:
- Gas metal arc welding (GMAW) - melting metal wire electrode
- Gas tungsten arc welding (GTAW) - non-consumable tungsten electrode
Gas metal arc welding (GMAW) includes
- active gas metal arc welding (MAG) and
- metal inert gas welding (MIG).
Gas tungsten arc welding (GTAW) includes
- tungsten inert gas welding (TIG) and
- plasma welding (WP).
Arnold uses gas-shielded arc welding in all common welding processes.
