Case Studies

Defects/Corrosion Inspection

Defects in the manufactured metal or composites components need to be quantitatively inspected to ensure they meet designed load capacity. In service structures could undergo fatigue and material degradation such as corrosion and aging. Thus, NDT is required in their whole life circle.

NDT at High Temperature

NDT of high temperature structures is a challenge in energy industry. With our NDT system with great resistance to high temperature, one could conduct local inspection by high frequency UT or large area inspection by guided waves.

Concrete Strength Evaluation

Nondestructive evaluation of concrete strength by acoustic methods like UPV has been widely adopted in civil engineering. However, UPV has poor consistency in evaluating concretes with different compositions and casting conditions. Surface acoustic wave (SAW) spectroscopy would be a reliable solution.

Nondestructive Characterization of Microstructures

Microstructure variance after heat treatment, casting, forging, welding and additive manufacturing is a big concern since it defines the mechanical properties. Typically, microstructure characterization involves cumbersome sample preparation and long process time. However, nondestructive characterization of microstructure would be a game changer.
