Objectif
The objective of this project is to specify, design and construct a welding robot for thick-steel fabrication, based on the best currently available technologies enhanced to meet the project's requirements. Standard equipment will be used for the mechanical and sensor systems, and a major part of the effort will be focused on software development to ensure that the robot will be extremely versatile and adaptable to new tasks with minimal reprogramming.
The concept involves measuring and identifying the component to be welded, welding it in position and finally inspecting the finished welds. The robot relies for its path instructions on a number of sensors, several of which will be used in concert to identify the start of the weld path, the weld seam trajectory, corner intersections and the weld finish-point. In addition, the welding process parameters are determined from databases, algorithms and knowledge-based systems, and as the welding proceeds the results will be assessed in real time and corrected according to other algorithmic rules or intelligent assessments. This system will remove many of the limitations of current adaptive controlled arc-welding robots.
The industrial partner in the project is a ship repairer whose operations are concerned with the replacement of damaged sections of hulls for which dimensional data are not available.
