There are more welds made each day with resistance and solid-state processes than with any other welding process. These include a broad range of overlapping technologies.

Generally, resistance welding technologies are those which use Joule, or resistance heating, in order to accomplish joining. Solid state processes are those which, through a combination of deformation and diffusion, allow joining to be accomplished without molten, and re-solidified material in the final bond area.

EWI is adept at all resistance-based processes:

  • Resistance Spot Welding (RSW)
  • Resistance Projection Welding (RPW)
  • Resistance Seam Welding (RSEW)
  • Flash and Resistance Butt Welding (FW and UW)
  • Magnetic Pulse Welding (MPW)
