In the submerged arc welding process the flux-covered electrode is replaced by the granular flux and a bare electrode. An arc between the electrode and job is the source of the heat and remains buried under a blanket of flux. This flux keeps the atmospheric contamination away. The process may be automatic or semi-automatic.See all results for this questionsp.info Where does the shielding come from in arc welding?In 1970, D.C. Smith ( 10) referred to the self-shielding electrodes as “covered electrodes turned inside out”, implying that in the self-shielding electrodes all the shielding must come from the inside of the wire, whereas with the flux-covered electrode the shielding is provided by the flux on the outside of the rod.See all results for this questionsp.info What is the current of an arc welding pool?General Operating Conditions Current: the total welding current can range between 100 and 3600 amps.
