摘要：

This paper studies an intentional force increase during the process of resistance spot welding (RSW). Known for decades, the forging force as a way of influencing weld quality has rarely been applied in the automotive industry. There has been little research in this area. In this paper, the effects of varying forging force are investigated using both experimental and analytical approaches. Through the analysis of dynamic electrical resistance, the mechanism of the forging effects is explored. This study achieves a better understanding of forging force application and shows the benefits of the forging force on weld quality.
