To achieve good welding results in various welding application, seam tracking technology is essential. In this thesis, seam tracking algorithm using cartesian coordinate welding robots are investigated and discussed. Many types of seam tracking methods are used in industrial field usually. Especially, vision system using CCD camera and laser diode are used to track the seam. A structured laser diode's light is introduced on the weld groove and the reflected light image is captured by CCD camera. The captured image is transformed into 8 bit pixel data. The seam tracking algorithm is developed by processing the 8 bit pixel data.
