Which is a variant of the submerged arc welding process?
Double submerged arc welding is a variant of the submerged arc welding process. The submerged arc welding process causes metal to coalesce through use of an electrical arc. The electrical arc is transmitted to the workpiece being welded through a consumable electrode.See all results for this questionWhere 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 questionWhat kind of steel is used in arc welding?These are A5.17 - Carbon Steel Electrodes and Fluxes for Submerged Arc Welding and A5.23 Low-Alloy Steel Electrodes and Fluxes for Submerged Arc Welding.See all results for this question
