In the medical applications of ultrasonic imaging, sound waves of high frequency are usually employed to produce in-depth cross-sectional images of internal organs. Special multi-element transducers ...

The phased array principle was introduced into ultrasonic testing because of its multiple advantages (Krautkramer, 1990; Rose, 1999; Ahmad et al., 2005). Some of the advantages of phased arrays over ...

Austenitic welds and welds that contain heterogenous weld materials are increasingly used in various industries. These welds can be used to manufacture components with enhanced or custom-engineered ...

SGS has carried out Phased Array Inspection in Nigeria for Daewoo E & C Co Ltd at the Gbaran Ubie Integrated Oil & Gas Project. Phased Array Ultrasonic Inspection is one of the latest weld inspection ...

Ageing infrastructure and the move towards more advanced materials raises new, currently unsolved, inspection challenges. Fatigue and creep damage are two of the most common modes of failure in ...

Description: ISO 19675:2017 specifies requirements for the dimensions, material and manufacture of a steel block for calibrating ultrasonic test equipment used in ultrasonic testing with the phased ...

A new system, developed by Tohoku University researchers in Japan in collaboration with Los Alamos National Laboratory in the US, takes 3-D images that can detect defects in metallic structures. The ...

At InnoTrans 2026 in Berlin, the Fraunhofer Institute for Nondestructive Testing IZFP in Saarbrücken will present two new technological solutions for the ultrasonic testing of wheelsets in rail ...

There are quite a few rather unconventional methods of propulsion, but perhaps one of the more curious approaches involved Helmholtz resonance, as demonstrated by [Junsun Hwang] et al. with a paper in ...

Nondestructive testing (NDT) refers to the inspection of materials to ensure their integrity and serviceability without damaging the components in the process. There are various NDT methods used by ...
