Experimental Study of Spot Weld Parameters in Resistance Spot Welding Process [PDF]
Mechanics and Mechanical Engineering, 2018 Abstract 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 interface of the sheets followed by its quick solidification ...
