Reference number : GC-2017-Q4-01661, amendment number : , agreement type : G, recipient legal name : Sinclair, Anthony (University of Toronto), recipient country : CA, recipient province : nan, recipient city : Ontario, recipient postal code : nan, program name english : Collaborative Research and Development Grants - Project, program name french : Subventions de recherche et développement coopérative - projet, program purpose english : Many industrial piping systems, such as those used for off-shore oil & gas recovery, are vulnerable to attack via_x000D_
from the corrosive fluids inside the pipe. Therefore, the pipes may have a protective inner layer or cladding_x000D_
made from a non-isotropic material such as stainless steel or Inconel. To avoid the costly and environmentally_x000D_
devastating effects of a pipe failure the weld seam linking two adjacent pipe sections together is ultrasonically_x000D_
inspected after construction. In this project, we attempt to develop more accurate techniques for conducting_x000D_
these inspections using two-dimensional ultrasonic arrays. By combining together the signals received at all the_x000D_
array elements after reflection from weld defects, one can focus on the areas of interest and thereby get more_x000D_
accurate information. However, such techniques are time consuming and require great amounts of computer_x000D_
data storage and processing power. We will be developing inspection methods and signal processing_x000D_
techniques to make the process more efficient while maintaining high accuracy., program purpose french : Many industrial piping systems, such as those used for off-shore oil & gas recovery, are vulnerable to attack via_x000D_
