Abstract
In automobile manufacturing industry, resistance spot welding is widely used. Car’s body is built by welding sheets of metal. In industry, common application where robots are being used is spot welding. In this paper, robot movement between two welding points, path followed while spotting, gripping, and pay-load-carrying activities, number of holds, moves, and possibility to enhance interaction between four robots were analyzed on offline robot simulation software ‘Delmia V5’. Body shop assembly line has four Fanuc robots that perform about 209 welding spots in 532 s. After modification and proper sequencing, 12.7% reduction in cycle time was observed.
