The various types of spot welding are available one of which is spot welding which is employed in manufacturing of automobiles, aircraft, steel household furniture, steel containers etcetera. For comparison, the process parameters are varied by varying different weld material to get optimization. There are several materials available for spot welding in which steel has higher electrical resistivity and lower thermal conductivity than copper. The material used for experiment is CRCA which is low carbon steel and most suitable for spot welding. Several materials have been used in experimental studies and processing activities to investigate and improve upon the process parameters in spot welding. This paper presents a review of the effect of changes in process parameters in spot welding.
