Abstract

The development of a novel laser-based seam tracking system for real-time industrial robot welding applications is presented. The system is based on a infrared diode laser, able to scan perpendicularly the seam joint using a laser scanner. A dedicated CCD camera collects the reflected laser light and the relative distance of the surface points under the sensor, form the sensor itself, is then calculated by simple triangulation techniques. The features of the seam profile such as the joint position and geometry are extracted and measured, with a precision of a some microns. In this paper the main components of the novel laser-based seam tracking system will be presented, as well as preliminary results obtained by our system. The laser-based seam tracking system will be of low cost, simple to use a nd rugged enough to provide trouble-free service in any welding or hostile industrial environment. This system will be the first to be developed and installed in Greece.
