On March 2019, OKOndt Group™ visited the USA one more time. Our American partners, who purchased the ultrasonic single-rail flaw detector UDS2-77 CR that can be used both for the crane rail and regular rails testing, needed a training on how to operate the equipment. Also OKOndt's specialists held a presentation of the USR-01 kit, which included a practical work on rails with flawed welds. It was a very busy and fruitful business trip — OKOndt Group got other requests for equipment and seminars.
