Ultrasonic testing of materials is one of most sophisticated and sought-after testing methods in the field of NDT. It uses high-frequency sound waves to examine, measure and detect abnormalities in a material. This method is generally used in industrial environments for measurement of wall thickness and as well as to detect cracks or discontinuities affecting the structural integrity of a material. Ultrasonic’s has grown to be a powerful tool in quality control and on-site inspection. The UltraCase uses high frequency (10 MHz to 20 MHz) ultrasound to measure the depth of hardness in materials. UltraCase hardness depth measurement can be done for case depth greater than 1.5 mm, in contrast with typical hardness measurement (destructive methods), Ultra Case provides a near real-time control of heat treatment, to reduce costs and detection capability. It can also reduce inspection costs, eliminate destructive testing of waste generated, and provides 100% inspection of components.
