Ultrasonic Testing (UT)
Ultrasonic Testing (UT) uses high-frequency sound waves that travel through the material to create a signal or image showing the internal structure of the material.
The sound wave can be reflected by cracks, Lack of fusions, lack of penetration, porosities, slags and other surface defects or shape of the surface. This portable equipment needs only one side access for the inspector.
The simplest form of UT is thickness measurement also known as UT thickness gauging where the thickness of material can be measured to evaluate the remaining life of a pipe or tank.
