Ultrasonic inspection of two samples of polyethylene pipes using PWI technology
Conducting ultrasonic inspection (ultrasound) of two samples of thick-walled pipes made of high-pressure polyethylene using Plane Wave Imaging (PWI) technology and combining partial images using coherent factor (CF) technology in order to increase the signal-to-noise ratio.

Inspection of a sample made of bronze BrX0.8 with a thickness of 100 mm
Many grades of bronze are a poor material for ultrasonic testing, since bronze has a high level of structural noise and noticeable anisotropy. This note describes technologies for reducing the level of structural noise using the example of using ultrasonic antenna arrays with high frequency.
