In the early summer of 2020, a customer from Turkey purchased from OKOndt GROUP ultrasonic equipment for rails testing — a hand-pushed trolley UDS2-73. In August, our experts keeping all the safety measures came to the customer to provide training, demonstrating all the extensive functionality of the flaw detector. During practice, the UDS2-73 detected flaws not only on the running surface, but also in the welded joints. OKOndt's specialists carried out several practical sessions, one of which took place at night, so that the customer's technical staff can learn to use the ultrasonic flaw detector in an effective manner at any period of the day.
