Abstract

Infrared sensing techniques used in arc welding and resistance welding process monitoring and control are presented. A variety of IR sensors have been investigated for use in monitoring and controlling weld bead width, penetration depth, seam tracking and cooling rate during arc welding, and nugget size and cooling rate during resistance welding. In addition, factors that affect or interfere with infrared sensing are discussed.
