In this article, the authors describe the technologies and means of ultrasonic thickness measurement for pipeline base metal and welded joints using phased array antennas with linear scanning by TOFD and DAF methods.
Abstract
The article describes the technologies and means of ultrasonic thickness measurement for pipeline base metal and welded joints using phased array antennas with linear scanning by TOFD and DAF methods. According to the thickness measurement data provided through specialized software, maps are obtained of the control objects thickness. The measurement results are given using these technologies, as well as the prospects for these methods development.

New Complex Solutions to the Nonlinear Electrical Transmission Line Model

TL;DR: In this article, with the help of an analytical approach, new complex singular and travelling dark solution for the nonlinear electrical transmission line is successfully constructed. But the results of these solutions differ from existing results, and general conclusions about these novel findings are given.
