Process Modeling of Mash Seam Welding


  • Mash seam welding (MSW) is a type of resistance seam welding widely used in mass production industries for products such as water heaters, aerosol cans, vehicle parts and steel mill coil joining
  • During welding, two sheets of metal to be joined together are held in an overlapping joint configuration (1 to 2 X sheet thickness) between a pair of electrode wheels usually having wide and flat edges
  • A weld seam is produced by Joule heating combined with pressure applied through the electrode wheels
  • Deformation in the resistance seam welding studied in literature is much smaller than that expected in MSW. Hence, an effective method of handling large deformation is essential
  • A MSW model can improve the understanding of the effect of process parameters on weld quality and the defect formation as well as the effect of post-processing on overgauge reduction
  • Such new knowledge provides the basis for engineering innovations in process control and optimization to obtain sound welds in MSW
