Applied Technical Services offers ultrasonic testing for several industries, including aviation. By performing aircraft ultrasonic inspections, our nondestructive testing experts can detect flaws that could potentially compromise safety and performance. Hidden imperfections on aircraft such as cracks, corrosion, and delamination are just some of the defects we uncover during our ultrasonic testing.
Ultrasonic testing (UT) is a nondestructive testing method that takes advantage of high frequency sound waves to analyze inconsistencies within materials. Our technicians use a transducer, or probe, to emit ultrasonic waves into the test object at a certain interval and angle. These waves then reflect back into the probe, which displays inconsistencies in the wave pattern if there is a defect present.
Types of Ultrasonic Testing
Traditional Ultrasonic Testing
Under conventional UT, the probe produces and receives a single ultrasonic wave at a fixed focal point and angle. This method requires technicians to know where to look for irregularities in advance.
Phased Array Ultrasonic Testing
Phased Array UT is an advanced method that can operate with a wide range of angles, giving it the ability to produce two and three-dimensional views of the flaw. This is an effective method for aviation parts that have complex shapes. Compared to traditional UT, the phased array method has more flexibility, resolution, speed, and accuracy for a more thorough aircraft inspection.
