Many industrial piping systems, such as those used for off-shore oil & gas recovery, are vulnerable to attack viax000D
from the corrosive fluids inside the pipe. Therefore, the pipes may have a protective inner layer or claddingx000D
made from a non-isotropic material such as stainless steel or Inconel. To avoid the costly and environmentallyx000D
devastating effects of a pipe failure the weld seam linking two adjacent pipe sections together is ultrasonicallyx000D
inspected after construction. In this project, we attempt to develop more accurate techniques for conductingx000D
these inspections using two-dimensional ultrasonic arrays. By combining together the signals received at all thex000D
array elements after reflection from weld defects, one can focus on the areas of interest and thereby get morex000D
accurate information. However, such techniques are time consuming and require great amounts of computerx000D
data storage and processing power. We will be developing inspection methods and signal processingx000D
techniques to make the process more efficient while maintaining high accuracy.
