Ultrasonic Testing

Ultrasonic Testing (UT) uses high frequency sound energy to conduct examinations and make measurements. Ultrasonic inspection can be used for flaw detection/evaluation, dimensional measurements, material characterization, and more.

Advantages

1. High penetrating power, so that detection of flaws deep in the part.
2. High sensitivity, permitting the detection of extremely small flaws.
3. Greater accuracy than other nondestructive methods in determining the depth of internal flaws and the thickness of parts with parallel surfaces.
4. Some capability of estimating the size, orientation, shape and nature of defects.
5. Nonhazardous to operations and has no effect on equipment and materials in the vicinity.
6. Capable of portable or highly automated operation.

Adavantages of GPR

Advantages of GPR(Ground Penetrating Radar) :-

GPR is Cost effective technique.
GPR is Hi resolution, vertically and laterally.
GPR is used in Numerous areas of application.

working principal of GPR(Ground-Penetrating Radar)

Working Principal:-

GPR(Ground-Penetrating Radar) is a impulse radar system that has been designed to penetrate earth materials.The GPR unit provides a continuous real-time profile of subsurface features in soil and geologic deposits. In GPR radar transmits high frequency when we transient electromagentic wave then waves are refleted and diffracted by changes in conductivity and praprties.
By the time travel by waves is used for analyzied tand material type information.
