Evaluation of feedback parameters for weld process control

Feedback control of the weld process is a step at improving weld quality while reducing lengthy inspection processes. The key to successful control of the weld process is to choose a parameter (or parameters) that can be monitored and provide the information necessary to correctly adjust the weld input parameters. The sensor used for this study detected penetration by monitoring the infrared radiation on the back side of the girth weld.© (1992) COPYRIGHT SPIE--The International Society for Optical Engineering.
