Development of a sensor-less methodology for monitoring quality of spot welding in real time

Resistance spot welding is widely used for joining metal sheet. Although many attempts have been made to perform the quality assurance, none of the methods available today can provide a satisfactory quality monitoring capability for spot welding without significantly sacrificing productivity of this...
