Rail Inspection

Rail Crack – Side

UT Inspection of Rail Structures

This training module presents the ultrasonic testing method as applied to the inspection of railroad rails.

Learning Outcomes

After completing this course, you will be able to:

– inspect the head, web, and central base regions of the rail to detect defects in the horizontal planes of the rail with a 0° beam transducer.
– inspect the rail web to detect web, weld, and bolt defects while using a 45° angle beam transducer.
– inspect the head of a rail to detect transverse fissures and weld defects greater than 5% of the head cross-section with a 70° transducer.

Understanding Ultrasonic Testing

Dual Media 150h

UT Dual Media Inspection Using an A-Scan Instrument

Time of Flight measurements are used to determine the distance of a reflection from the source of the sound. UT test instruments do not account for the velocity of sound differences through different materials, such as the water path and material under test. This course shows you how to use an A-Scan Instrument to accurately perform these measurements.

Learning Outcomes:

After completing this course, you will be able to:

– analyze the distance scale on the A-Scan for the correct distance of a second media whose velocity is different from the velocity entered for the material under test
– make more accurate detection calls

Specular and Non-Specular Reflections

Specular and Non-Specular Reflections

Screen interpretation is key to being a skilled operator. Typical UT operators may be familiar with the beam divergence formula and that it describes the beam divergence angle. This course will provide UT Level II and Level III personnel with a deeper understanding of the effects of beam divergence during ultrasonic inspections.

Learning Outcomes:

After completing this course, you will be able to:

– understand echo signal characteristics
– make more accurate detection calls

Guy with Bull Horn

UT Sound Energy Transit Time

Provides the principles of how to analyze the time of flight or travel time of sound energy movement during the ultrasonic inspection of material.

Learning Outcomes:

After completing this course, you will be able to:

– use ultrasonic inspection equipment to measure the “distance to” any reflector within the material under test

USM Go+

GE-USM-GO-GrupoTestek-Industry 480 x 480

UT USM Go+ UT for the Busy Learner

This course applies to anyone who has a USM Go+ and has never performed an ultrasonic inspection of metal parts or railroad tracks. This version of training material is for personnel wishing to learn how to use the USM Go+ and is designed for those who have busy schedules with limited daily spare time to apply to learning new methods for inspecting material quality. By utilizing shorter learning sessions several times a week, rather than multiple-hour sessions once or twice a week, knowledge absorption and retention are greatly improved. This course addresses this issue by breaking up the entire course into smaller units called “units.” This method presents the course to learners in ready-made short sessions to apply to their learning process.

Learning Outcomes:

After completing this course, you will be able to:

– implement the basic principles of ultrasonic inspection
– adjust and operate the USM Go+ to perform an ultrasonic inspection of railroad rails or other parts
– perform this inspection in the main structural zones of rails or any structural geometries
– use three primary sound beam angles ( 0 degrees, 45 degrees, and 70 degrees) to perform a complete inspection over reference reflectors in rail or other geometrical structures in less than 5 minutes with 80% accuracy
