“…Moreover, a linear electronic scan with TFM reconstruction is proposed to achieve better results. Recently, some investigations focused on ultrasonic PA signal enhancement to improve delamination inspection in composites, Abdessalem et al 122 applied the threshold modified S-transform (TMST) approach to improve image quality and resolution to enhance delamination detection; similarly, TMST and Shannon energy can be used for this aim. 123 In addition to discussing subjects, numerous modern approaches can be suggested and investigated to detect delamination defects in composite components based on ultrasonic techniques, phased arrays, and signal correlation algorithms.…”

Ultrasonic testing procedures are among the most extensively used techniques in non-destructive testing and non-destructive evaluation systems. Meanwhile, phased array inspection or phased-array ultrasonic testing techniques as a well-known type of ultrasonic testing in advanced non-destructive testing systems are utilized in numerous applications, including oil and gas, medical imaging applications, railway, automotive, marine, and aviation industries. Phased-array ultrasonic testing-based methods can also be used in a variety of weld inspections, bond testing, thickness profiling, flaw detections, corrosion inspections, and in-service crack detection. The rapidity, safety, easiness, affordable price, and accurate visualization of phased array in measuring the defect characteristics such as size, shape, depth, and orientation allow its wide usage and even as a substitute for other inspection methods like radiographic methods. In phased array methods, more than one sound wave is employed to enhance the reliability and flexibility of inspection through the operation of several transducer assemblies, involving 16 to 256 small individual elements. Titanium having many desirable properties like high strength to weight ratio found many industrial applications, which highly necessitates its persistent inspection. For this aim, the present study focuses on the application of the phased-array ultrasonic testing technique for inspecting Ti components specifically in additive manufacturing, welding inspections, and defect detection of complex geometries and composites. Moreover, modern applications and improved computation methods are discussed. The development of phased-array ultrasonic testing inspection systems, particularly high throughput and efficient in situ and mobile equipment, and new computation methods will open new horizons toward the highly sophisticated inspection procedures.

“…Examining composites carries some major technical challenges such as the attenuation, scattering and absorption of the signal and the shadowing effect of multiple damage can have an influence on the received results. The majority of these difficulties can be overcome by using phased array ultrasonic testing (PAUT), involving signal processing and correction with advanced algorithms, such as the threshold modified S-transform (TSMT), combined with multiple pulser-receiver elements working together [5][6][7]12]. Research described in this article has been done in order to determine whether visible irregularity in the composite skin structure of an aileron is a production flaw or another kind of defect.…”
