US4449029A - Acoustic wave spot welder adaptive

The thickness of the molten weld nugget is continuously monitored during resistance spot welding, and when proper penetration is achieved the applied current is turned off. An ultraic transducer housed in the water cooled lower welding electrode transmits ultraic pulses into the workpiece and receives waves reflected at each solid/solid and liquid/solid interface. USE OF DYNAMIC RESISTANCE AND DYNAMIC ENERGY 1.5. Dynamic electrical resistance The electrical contact is responsible for Joule effect heating at the faying surface and, consequently, by the formation of the weld nugget during the steel sheet welding. The contact electric resistance at this place changes rapidly during the welding time and, therefore, is dynamic in nature .
