Abstract: A modular production system and method includes an endless transport path defining a loop. A plurality of work cells in which processes are performed on a workplace are disposed in a sequence along the transport path. The work cells include an inner spot welding cell, an inner remote laser welding cell, and an outer roller flanging and laser welding cell. A transporter follows the transport path and selectively transfers the workplace between the work cells along the transport path. The transporter selects at least some of the work cells and makes a stop at the selected work cells, and the transporter bypasses any unselected work cells.
