Research on the Application of 3G Robotic Welding Guns to the Welding of Body-in-White Based on Delmia

摘要

3G welding gun is a new kind of welding guns which uses servo motor as the driving device. And it is of modularity, simplicity, robustness and high performance and has obvious advantages compared with traditional welding guns. This paper exploited robot payload check program to make comparison of the differences between OBARA welding guns and 3G welding guns. The results verified the advantages of 3G welding guns. A case study to the application of 3G welding guns to the body side was conducted, and Delmia, a 3D platform for robotic simulation and OLP, was used to create the robot welding programs. Finally, the timing chart of welding process by means of 3G welding guns was analyzed.
