ULTRASONIC TESTING (UT)

NDT-Tank-Inspection

Ultrasonic Testing (UT) is non-destructive testing method used to detect surface, subsurface, internal and dimensional flaws.

The method utilizes high-frequency sound waves that are transmitted throughout the material being tested in order to conduct a thorough inspection.

The method can detect cracks, seams, voids and inclusions of foreign material.

UT is often performed on steel and other metals and alloys, though it can also be used on concrete, wood and composites.

QUALIFIED STAFF, STATE-OF-THE-ART EQUIPMENT

Quality Inspectors Limited (QIL) has a highly-trained staff of certified ultrasonic inspectors who utilize advanced instrumentation and data reporting capabilities to quickly and accurately detect and identify flaws and measure material depth for a variety of applications and industries, including aerospace, military, and commercial.

HOW QIL UT INSPECTION WORKS

QIL inspectors use Ultrasonic testing, or UT, in the examination of machine parts and welds and to determine material thickness. This inspection involves the use of complex electronic equipment that is connected to one or more transducers. These transducers generate and detect high-frequency sound waves that, after being transmitted through a test specimen, bounce back to reveal defects or to calculate the material thickness.

Because it requires access to only one side of the test specimen, ultrasonic testing is often used in situations where radio-graphic examination is not possible. Element maintains full-service ultrasonic laboratories to offer in-house, onsite, and field inspections and certifications. Whether your inspection requirements are for raw materials or fracture-critical components, QIL offers the equipment, expertise, and capacity for the task.

Some of the advantages of ultrasonic inspection include:

• It is 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.

• It is highly accurate in determining reflector position and estimating size and shape.

• Minimal part preparation is required.

• Electronic equipment provides instantaneous results.

• Detailed images can be produced with automated systems.

• It has other uses, such as thickness measurement, in addition to flaw detection.

IDEAL FOR ONSITE APPLICATIONS

Ultrasonic inspection is an extremely effective method for use in field locations due to the portability of the equipment and the ability to evaluate and record results at the time of inspection. Element offers a full range of ultrasonic field inspections.
