They can be used to find cracks, flaws or thickness. They are used for inspecting paintings and coatings, and materials themselves. Ultrasonic test systems find their way into the automotive, aerospace, energy, medical and metalworking industries, among other applications.
Conventional ultrasonic test systems use ultrahigh frequency sound pulses bounced from the ultrasonic tester through the material and back to the tester. However simple that description of ultrasonics may sound, advancements in the technology have made it an advanced tool for more sophisticated applications, such as seam and pipe inspections, gage measurements, long-distance railway inspections ...
