PA ultrasonic testing of AT weld joints in rails

Abstract

In this paper, a comparative test with two different ultrasonic systems was performed on the aluminothermic welded joints of the rail. The test was carried out with a conventional system and a phased array system. Sensitivity adjustment was carried out on artificially made reflectors on rail and a comparative test on the rail with real imperfections. Due to the complex geometry of the rail and the type of errors that can occur, the test itself can be a challenge in selecting the test system and technique. The aim of the paper is to show, considering the limitations of ultrasound systems, test results that indicate the advantage of a phased array ultrasound system compared to a conventional system.
