Welding process monitoring and control system for a pipe welding mill has been developed. The system consists of three subsystems, namely for control of penetration from the reverse side of the weld pool, control of the pipe weld formation and weld following. Design of these subsystems using a technical vision system, as well as hardware and algorithmic methods for minimizing the effect of optical (blinks and flashes due to the welding arc) and mechanical (scratches, rust, burrs) interferences, are considered. The system provides high real-time measurement accuracy.
Keywords: arc welding, butt joint, welding process monitoring, technical vision system, automatic control of the welding process, penetration monitoring, following system, weld formation monitoring, reinforcement bead
