Implementation of Dynamic Resistance Database for Weld Quality Improvement of Spot Welder

스폿용접기의 용접품질 향상을 위한 동저항 데이터 베이스 구축

A dynamic electrical parameter monitoring device was designed to simultaneously record the instantaneous value of voltage, current, power, and resistance during spot welding. The data obtained using this technique have been analyzed in term of the relationships of these parameters to the phenomena occuring during the formation(surface break-down, nugget formation and mechanical collapse) of spot weld. Finally, a database implementation is undertaken to develop techniques for improving weld quality of the resistance spot welder.
