Resistance spot welding is a strongly coupled electrical, thermal, mechanical and metallurgical process. The process itself is very dynamic and complex in nature. Over the recent years, there has been a growing interest in improving the understanding of the physics associated with resistance spot welding process. Knowledge in this regard is essential for the reliable process monitoring and the development of control systems. The key to achieve such a goal is to quantitatively characterize the mechanical, electrical and thermal contact phenomena during resistance spot welding. Finite element modelling has been proven to be a powerful tool for such a purpose. The objective of this research is to analyze the transient mechanical, electrical and thermal effects of during the resistance spot welding.
