Abstract

Optical sensor technology for arc welding control is critically reviewed. The basic sensing and control problems associated with arc welding are presented with joint tracking as the primary emphasis. The problem of imaging of the weld area and design of optics is considered including the unique coaxial optical system. General versus structured illumination is reviewed, with the various approaches described. Conclusions are drawn relative to the present state of the technology and expectations for the future.
