On October 1-4, 2023 OKOndt GROUP attended Railway Interchange 2023 - the largest North American railway event. This time the exhibition took place in Indianapolis, Indiana, USA (Indiana Convention Center) and brought together over 700 exhibitors and more than 8, 000 visitors who are the major influencers in the industry. Thank you to everyone who was with us at the RI 2023!

Applications

Application areas of nondestructive testing

Both the manufacture defects – the ones that appear in the process of production – and in-service defects of fatigue type may develop (fig.1) in various metal products. The cracks may develop at different angles to the surface growing to considerable depths thus causing the threat of a product breaking when in service.

Eddy current testing System of rails EDC RAIL 5065 allows to perform an automated eddy current testing for presence of the surface defects. Main defect types that are subject to testing by the System are the surface defects such as cracks, laps, hairline cracks located on the outer surface of the rail head and rail shoe of 49Е1, 60Е1, UIC60 rail types etc in accordance with EN 13674–1–2017 requirements.

Since early 2010, the OKOndt Group company has been conducting scientific-and-research and experimental-and-design works in the field of automation of the non-destructive testing methods for the railway wheelset elements testing. Implementation of the developed Systems for automated ultrasonic testing AUTS Axle-4 OS-4 and mechanized magnetic particle testing OS-38 (hereinafter – the Systems) enabled the enterprises of PJSC «INTERPIPE NTRP» and PJSC Lugcentrokuz a. S. Monyatovsky to promote their product at the world market and successfully certify their quality labs for compliance with requirements of European and American regulatory documents.

Ultrasonic method occupies a special place in non-destructive testing. Being one of the first and the most widespread it allows to detect both surface and inner defects of various types, perform thickness gauging and non-destructive structuroscopy.
