Ultrasonic Nondestructive Evaluation:

Using ultrasound to find and evaluate flaws in engineering products and structures. This is useful in the following fields:

  • Aerospace
  • Nuclear power plants
  • Oil & gas piplines
  • Ships, trains, and automobiles
  • Electronics
  • Bridges
  • Process control in manufacturing


Two-dimensional sector-scan image of a flaw inside a girth weld linking two large sections of an oil pipeline. Blue lines designate path of ultrasound; the two coloured echoes represent ultrasonic pulses diffracted from the top and bottom extremities of the weld defect. This particular flaw is approximately 3 mm in depth emanating from the weld root (inner wall of pipeline).
