The topics of the four sessions are: (I) Design, Calculation and Prediction Models For Metallurgical Processes/Conception; (II) Inspection and In-Service Monitoring; (III) Fabrication, Quality Assurance; and (IV) Expert Systems, Data Banks and Future Possibilities. Session I includes papers on the use of computer technology to establish the quality of the welded joints; computer-aided design system for design of fillet welds with optimum shape; and the use of numerical simulation software for predetermination and optimization of the mechanical resistance of brazed joints. The papers in Session II cover topics such as acoustic emission testing; eddy current inspection system for weld testing; and holographic imaging of weld cracks. Session III includes papers on a computer controlled friction welding system and a CAQ-system for welding workshops. The presentations in Session IV include an approach for writing conventional software and expert systems for welding engineers and an expert system for robotic welding.
