ABSTRACT:
Computer-assisted welding process and system, based on a view of the welding scene. This invention relates to a computer-assisted welding process and system. This automatic welding process, assuring the processing of images taken during a welding scene, is based on a learning from the welding cases already processed. It comprises the operations for prior establishment of relationships between the parameters of welding; of installation, in hardware or software form, of these relationships in a welding system, then the execution by this system; of pictures of a welding scene in progress; of analysis of each of these pictures to measure certain of the welding parameters; of evaluation, from these relationships, of values for correction of the welding parameters; of intervention, as a function of this evaluation on the welding in progress. This process is used by a system having a welding head able to take the pictures, and a processing and control unit able to apply said process. This finds numerous applications all high-technology industrial fields, such as the aeronautics and nuclear fields.
