Influence of Welding Parameters on Bead Geometry in corrosion steel plate Submerged arc welding
The modern submerged arc welding (SAW) is an arc welding process, in which one or more arc(s), formed between one or more bare wire electrodes and the work piece, provides the heat for the coalescence. In submerged arc welding, shielding of the weld arc is done using a granular flux which is fed into the weld zone using a hopper.Influence of Plate Geometry on the Welding Residual corrosion steel plate Submerged arc weldingSubmerged arc welding (SAW) is used to make a fully penetrated butt weld in 10 mm, 40 mm, and 50 mm thick steel plates with both circular hollow section and flat plate geometry.
