Welding in Energy-Related Projects

Welding in Energy-Related Projects contains the proceedings of the Welding Institute of Canada's Second International Conference held in Toronto, 20-21 September 1983, on the theme ""Welding in Energy-Related Projects."" The contributions to the conference offer a unique overview of many areas of technology from research and development studies to construction and operation, and as such provide a comprehensive reference source. This volume contains 44 papers organized into eight sections. Section I contains studies on materials and weldability of steels for energy structures. Section II covers welding techniques such as flux-cored arc welding, root pass welding, and automatic welding. Section III on welding control systems includes studies on such as integrated robotic welding and microprocessor technology in automatic integrated welding systems. Sections IV and V presents studies on welding of high-alloy systems and welding procedure optimization, respectively. Section VI covers quality assurance and inspection of piping systems. Section VII takes up the properties of welds. Section VIII presents stress and strain analyses of welds.

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.
