September 2019 was a very eventful month for OKOndt GROUP. After participation in Railway Interchange-2019, the specialists of our company went to Miami where they held a practical seminar for OKOndt client. The aim of the seminar was to teach Gonzales & Sons' employees how to operate the USR-01 kit and UT single rail trolley UDS2-77 – NDT devices which American company had purchased from OKOndt GROUP before. The workshop lasted for several days, attendees got few opportunities to watch expert’s actions then tried to operate flaw detectors by themselves. The training went well. Technical staff of Gonzales & Sons studied functionality of both devices. They expressed confidence that they will be able to conduct nondestructive testing of railways successfully.
