UT TOFD-Time of Flight Diffraction

Course details

Ultrasonic testing with Time Of Flight Diffraction is a new specific technique. This technique is very often used for pipelines testing, weld testing and pressure vessels testing for detection of imperfections with improper orientation for conventional UT. Method is suitable for detection of defects in welds. Especially, because its high velocity of inspection is suitable for automatic scanning of long welds like pipe welds

What you will learn

Training is focused on basic TOFD knowledge and practical knowledge like probe selection, arrangement of testing and mainly evaluation of indication. 

Participant will get practical information about used techniques, difficulties, which can occur during testing and equipment which can/must be used for inspection. Trey will gain knowledge about instrument setting and about testing arrangement (like scan arrangement, multiple zone scanning and probe selection). Greatest emphasis is placed on signal evaluation, data collection and reporting of findings.
