Electroslag welding (ESW) produces the coalescence of metals through molten-slag melting the filler metal and the surfaces of the workpieces to be welded. The weld pool is shielded by this slag, which moves along the full cross section of the joint as welding progresses. The process is initiated by an arc that heats a granulated flux and melts it to form the slag. The arc is then extinguished by the conductive slag, which is kept molten by its resistance to the elec..
