Description
Weld Quality: The Role of Computers documents the proceedings of the International Conference on Improved Weldment Control with Special Reference to Computer Technology, held in Vienna, Austria, 4-5 July 1988, under the auspices of the International Institute of Welding. 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.

Person
Dr. Sam Stuart is a physiotherapist and a research Fellow within the Balance Disorders Laboratory, OHSU. His work focuses on vision, cognition and gait in neurological disorders, examining how technology-based interventions influence these factors. He has published extensively in world leading clinical and engineering journals focusing on a broad range of activities such as real-world data analytics, algorithm development for wearable technology and provided expert opinion on technology for concussion assessment for robust player management. He is currently a guest editor for special issues (sports medicine and transcranial direct current stimulation for motor rehabilitation) within Physiological Measurement and Journal of NeuroEngineering and Rehabilitation, respectively.
