Automatic Processing System of Welding Spots in Auto-Body Welding Lines

Assigning welding spots to stations in the design of an auto-body welding line is a tedious job and error-prone. In this paper, an automatic processing system of welding spots has been implemented on the platforms of the commercial software, CATIA and Solid Edge. The geometric feature based technology is used to recognize welding spots automatically. The corresponding station is found for each welding spot according to the order of stations and the types of welding spots automatically. The system provides other convenient functions to facilitate the processing of welding spots as well. It has been used in the design of auto-body welding lines very successfully.
