Electroslag welding (ESW) is a method of strip cladding, but differs from SAW strip cladding in that the arc is created between the electrode and the workpiece.
The welding flux that is put into the joint melts and a slag pool is produced, which then increases in depth.
When the temperature of the slag and its conductive capacity thereby increases, the arc is extinguished and the welding current is conducted via the molten slag where the necessary welding energy is produced through resistance.
This method can be used for joining thicknesses of 25 mm (1 in.) and above.
