ABSTRACT:
A fully integrated automated laser weld process control system (LWPCS) and method of controlling the fabrication of structural parts, particularly for shipbuilding and other industries. The LWPCS defines joint and weld quality attributes as process control variables and integrates these weld quality variables, along with the more traditional process parameters such as laser power, wire feed, GMAW voltage and active seam tracking, into a closed-loop monitoring and control system. The LWPCS includes a central processor and a plurality of subsystems that control laser beam positioning, vision-based monitoring and image processing, active weld-quality monitoring and inspection, adaptive beam delivery, and seam tracking. Cross-communication between subsystems is managed by the central processor. In addition to process control, the system extracts weld quality attributes during the weld process and provides immediate documentation of the weld quality.
