Resistance spot welding is a comparatively clean and efficient welding process that is widely used in sheet metal joining. This process involves electrical, thermal and mechanical interactions. Resistance spot welding primarily takes place by localized melting at the inter-face of the sheets followed by its quick solidification under sequential control of water cooled electrode pressure and ?ow of required electric current for certain duration. In this experimental work the tensile tests and the spot weld diameter were studied. The objectives of this analysis is to understand the physics of the process and to show the influence of the electrical current, weld time and the type material in resistance spot welding process.
