Typically around 100 welds in a car body have to be manually welded in the final welding stations. This is due to welds being spread over large areas, large tolerances, bad fit-up and several variants existing. This paper describes how these problems have been solved by using specially adapted arc welding equipment allowing the robot to fully utilize its agility, a sensor to locate and measure the joints, and weaving and other welding techniques to weld joints having large gaps. In order to achieve an acceptable programming time despite a very large user program, the programs include standardized program modules for searching and welding. The results is a station which virtually welds all joints on one side of the car body.
