Ultrasonic Flaw Detection Service

Customers can avail technologically advanced service of Ultrasonic Flaw Detection Service. Ultrasonic Testing makes use of high frequency sound energy to take measurements and also to conduct inspections. The inspection unit has the following functional units:

* Pulser / Receiver: it is an electronic device capable of producing high voltage electrical pulses.
* Transducer: It is driven by the pulser and generates high frequency ultrasonic energy. It also transforms the reflected wave signal into an electrical signal.
* Display devices: The electrical signal is displayed on these devices.


The reflected signal strength is displayed versus the time from signal generation to the time, when a echo was received. Signal travel time is directly related to the distance that the signal has traveled. The information about the reflector location, size, orientation and other features can be gained from the signal. Ultrasonic inspection is used for flaw detection & evaluation, dimensional measurements and material characterization among others.

This method is one of the most versatile Non Destructive Testing methods. The major advantages of this method over other methods are as follows:

* Sensitive to both surface and subsurface discontinuities.
* The depth of penetration for flaw detection or measurement is superior to other NDT methods.
* Only single-sided access is needed when the pulse-echo technique is used.
