Ultrasonic testing (UT) is a non-destructive testing (NDT) method that works by using high-frequency sound waves to detect cracks and damage to a part of an object or material. This method can detect surface, sub-surface, internal, and dimensional defects. The ultrasonic test method can also be used to determine the thickness of a material, such as determining the thickness and corrosion that occurs in a pipe. Geochem Survey provides ultrasonic testing services to test material thickness, corrosion and defects on an object.
