Hc. Wikle et al., SURVEY OF INFRARED SENSING TECHNIQUES FOR WELDING PROCESS MONITORING AND CONTROL, Zhongguo gongcheng xuekan, 21(6), 1998, pp. 645-657
Infrared sensing techniques used in are 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 bea
d width, penetration depth, seam tracking and cooling rate during are
welding, and nugget size and cooling rare during resistance welding. I
n addition, factors that affect or interfere with infrared sensing are
discussed.
