Shielding is obtained entirely from an externally supplied gas mixture.See all results for this questionWhat kind of electrodes are used in arc welding?Depending upon the process, the electrode is either consumable, in the case of gas metal arc welding or shielded metal arc welding, or non-consumable, such as in gas tungsten arc welding. Consumable electrodes are those which melt away or consumed during the welding process. These electrodes are of low melting point materials.See all results for this question
