Ultrasonic testing is the most widely used non-destructive testing technique in the world. It is also one of the most versatile and cost effective methods for detecting defects in materials.

Because ultrasonic testing does not require access to the interior of a specimen, it can be performed on all types of materials, from metal to plastic and fibreglass. It can be used to inspect a variety of components including engines, transmission components, gears, bearings and welds. Ultrasonic inspection is also often used as a quality control method during manufacturing processes such as welding or grinding.

The advantages of ultrasonic testing:

Non-destructive testing

Ultrasonic testing does not damage the part being tested because no contact is made with the sample being inspected. This makes it ideal for inspecting parts where damage caused by traditional methods would render them useless or even dangerous (such as automotive parts).

Highly accurate

The accuracy of an ultrasonic test depends on many factors including: frequency range (frequency range determines sensitivity), transducer size/shape (size/shape affects resolution), type of mount (mount affects sensitivity) and whether you are using single or dual elements (single elements are more sensitive but less stable than dual elements).

Real-time results

Ultrasonic testing produces real-time data about the object being inspected, allowing you to observe changes as they occur during the test cycle instead of having to wait until the end of the test cycle for results.

Fast testing times

Ultrasonic testing provides fast results because ultrasonic waves travel through materials quickly and easily without being absorbed by them like light waves are by glass windows or water molecules are by oil slicks on water surfaces.

Wide range of applications

Ultrasonic testing can be used on all types of materials such as metals, ceramics and composites because it can penetrate these materials without damaging them. It’s also useful for detecting flaws inside objects such as pipes and tanks because these structures have uniform thicknesses that allow ultrasound waves to travel through them without losing much energy or getting absorbed by surrounding materials (as happens with other types of tests).


Ultrasonic testing can be used to inspect virtually any kind of material or product that requires inspection after manufacturing, including parts that have already been assembled into a finished product. This makes it much easier for companies to ensure that their products meet quality standards before being shipped out onto the market. It also allows them to catch defects as early as possible so that they can be resolved before shipping rather than later down the line when they could lead to more significant problems like recalls or safety concerns for customers.
