Path welding with manual jig change
Due to the small batch sizes, the line has to be changed over very frequently. Each time, refitting results in a very long production downtime.

Case
Cell description
The system consists of two KUKA KR16 L6 robots for path welding. Bumper parts are produced for the automotive industry. The robots work on a turntable that can hold a fixture on each side in which the parts to be welded are clamped. The robots weld the parts on one side, while the operator removes the finished parts from the second unit and inserts new parts.
Task
The customer produces batch sizes of a few hundred pieces on the line. The system therefore needs to be changed two to three times a week. As the new fixture can only be inserted imprecisely during refitting, all welding programmes have to be re-taught. As a result, a retooling operation takes up to eight hours, i.e. an entire shift during which production cannot take place.
