The paper focuses on the study of Electro Slag Strip Cladding (ESSC) process carried out in the industry for
corrosion resistant overlay on the inner surface of the pressure vessel shells. The process principle, process initiation &
process parameters of ESSC have been discussed. The welding parameters which are controlled by the welder during the
process are current, voltage, speed, flux height, electrode, strip offset. There is a specified range of values for these
parameters to be maintained. If this range is violated, then it will seriously affect the welding microstructure &
ultimately the weld chemistry & strength. This paper discusses about how a change in these parameters affect the weld
obtained.
