Comparative study of small scale and ‘ large scale ’ resistance spot welding

  title={Comparative study of small scale and ‘ large scale ’ resistance spot welding},
  author={Byung Hoon Chang and Ming V. Li and Yong Zhou},
An incrementally coupled electrical – thermal – mechanical model is developed to simulate small scale resistance spot welding (SSRSW) using the finite element method. This numerical model is then employed to study the differences between SSRSW and ‘large scale’ resistance spot welding (LSRSW). The variations in contact area, current distribution, and temperature profile at the workpiece/workpiece interfaces are compared. The computation shows that the difference in electrode force could be the… CONTINUE READING
