Description: Abstract :

The research involves in design, calibration and implementation of a joint fit-up pre-weld inspection station which provides feed-forward quality control through adaption of welding procedures in a felxible Automation Robotic Welding System. Data derived from inspection station (using Laser range-finder system) is processed by a Knowledge Base Expert System (PIKBES) with the ability to handle expertly established welding procedure "Models". The system provides a cost effective means for on-line quality control for small batch welding operations and is applicable to a wide range of weld joints in Carbon na d Carbon Manganese Steels Welded by the GMAW process. Full factorial experiment have been carried out to validate the ability of PIKBES to assure satisfactory joints by automated welding given considerable variability in joint fit-up.
