Ultrasonic testing and phased array ultrasonic testing have similarities in their primary working principle. However, the similarities end as factors like incident angles, focal points, and the number of transducer elements are very different for both testing methods.
When testing ultrasonic transducers, you should start with the basic physical dimension measurement. Then the next step should be functional testing, which consists of pulse-echo measurement at a specified distance and reflecting off a specified predetermined target.
A Distance Amplitude Correction (DAC) is a method of compensating for the fact that the pulse-echo response of a reflector will decrease as the distance of the reflector from the ultrasonic probe increases.
In Oct. 26th 2011, NDT-KITS signed a contract with SGS (www.sgs.com), and formally become their supplier of ultrasonic testing calibration blocks. SGS is the world’s
The ultrasonic transducer is a very important part of the ultrasonic flaw detector. The transducer incorporates a piezoelectric element, which converts electrical signals into mechanical
Ultrasonic pulse-echo devices are built with a transducer which produces a wide-band pulse that is subjected to the test material during testing.
The conversion of electrical pulses to mechanical vibrations and the conversion of returned mechanical vibrations back into electrical energy is the basis for ultrasonic
Remote field testing (RFT) is an electromagnetic method of nondestructive testing whose main application is finding defects in steel pipes and tubes. Remote field
A typical ultrasonic flaw detector consists of several functional units, such as the pulser/receiver, ultrasonic transducer, and display devices. A pulser/receiver is an electronic
Angle beam transducers and wedges are typically used to introduce a refracted shear wave into the test material. An angled sound path allows the sound
Electrical conductivity tester is a tool that test the conductivity of the metals. like aluminum, copper, and other non-ferrous metals. I. What is the
There are 3 main NDT methods for the inspection of welding surface crack detection, Liquid Penetrant Testing (PT) , Magnetic Particle Testing (MT) and Eddy
