Ultrasonic testing is a non-destructive testing (NDT) method where ultrasonic waves are passed over the material or specimen to check for internal flaws.
An ultrasound transducer which is hooked up to a diagnostics machine is separated from the material by a couplant that improves the transmission of ultrasonic energy for testing purposes. For steel testing, water or oil can be used as a separating method.
The test is highly penetrative, detecting potential flaws deep into the material and has great accuracy especially when compared with other non-destructive testing methods. Furthermore, this testing method is also very portable which means that steel material can be tested on site if required.
The reflected ultrasound wave is measured for consistency - if the amplitude wave is not consistent, this will be indicative of a flaw in a material. A good example of an ultrasound test would be for measuring the thickness of pipe. Ultrasonic inspection is not suitable for surfaces which are very small, with a rough surface or irregular in shape - however the testing method lends itself well to heavy steel plates, pipes and fabricated sections due to the consistent nature of the product.
HZZSTEEL are able to arrange for your steel order to be inspected by a third party testing house, and ultrasonic inspection is one of many testing services we offer.
