What is shear wave ultrasonic testing?

Shear wave ultrasonic testing uses ultrasonic energy that is reflected back to the transducer from indications within a material and or weld. This is displayed as an A-scan, from which an operator can review the relevant information to assess the integrity of the component.

What are the limitations of ultrasonic inspection?

Disadvantages of Ultrasonic Testing Techniques:

Training is more extensive than other methods.
More expensive than other methods.
Difficult to use on thin materials.
Part Geometry can cause complications.
Needs relatively smooth surface to couple transducer.

What are the two basic ultrasonic inspection techniques?

Ultrasonic testing can be performed using two basic methods – pulse-echo and through-transmission. With pulse echo testing, the same transducer emits and receives the sound wave energy.

Why Ultrasonic testing is done?

Ultrasonic testing (UT) is a non-destructive test method that utilizes sound waves to detect cracks and defects in parts and materials. It can also be used to determine a material’s thickness, such as measuring the wall thickness of a pipe.

What can ultrasonic inspection detect?

What is the advantage of ultrasonic?

Advantages of ultrasonic inspection as a method of Non-Destructive Examination are: Internal defects can be detected and sized when a validated procedure is applied. Thick specimens take no more time to examine than thin ones, assuming correct instrumentation set up. Access to only one side of the component is needed.

Is ultrasonic waves harmful?

Although Ultrasound cannot be heard by humans, at high decibels it can still cause direct damage to human ears. Ultrasound in excess of 120 decibels may cause Hearing damage. Exposure to 155 decibels causes heat levels that are harmful to the body. 180 decibels may even cause death.

What kind of test is shear wave inspection?

Shear wave testing, also known as angle beam inspection, is an ultrasonic testing technique used primarily for weld inspections. A probe consisting of an ultrasonic transducer coupled with a plastic or epoxy wedge introduces an ultrasonic beam at an angle into a test area.

How does shear wave ultrasonic testing ( UT ) work?

Shear-Wave Ultrasonic Testing, also known as an “angle-beam inspection,” is a UT technique that uses a probing ultrasonic transducer with a plastic wedge to test component strength. The probe conducts an ultrasonic beam at an angle into the test area, moving move back and forth as it detects any flaws based on the refraction of the beam.

How does the Shawcor UT shear wave work?

Shawcor UT Shear Wave sends an ultrasonic beam into the test area at an angle. The sound wave reflects back to the transducer and the display shows the distance and strength of the ultrasonic signal, from which discontinuities and anomalies can be detected and evaluated.

How are weld quality tests done at Shawcor?

Non-destructive testing using ultrasonic shear wave or phased array methods to collect full volumetric weld quality data. Shawcor’s experienced technicians perform shear wave and phased array ultrasound testing to ensure code compliance of welds in various materials.

What is shear wave ultrasonic testing? Shear wave ultrasonic testing uses ultrasonic energy that is reflected back to the transducer from indications within a material and or weld.
