Code: UT L1 (for Level I), UT L2 (for Level II), UT L3 (for Level III)


By using ultrasonic method you can identify location and orientation of imperfection or the material wall thickness. Ultrasonic method is not strictly limited by thickness, material type and part type. It is possible to detect both internal and surface defects and also both volumetric and planar defects.


This is a comprehensive course for individuals with little or no experience in ultrasonic testing; as well as a refresher course for individuals who need to brush up on ultrasonic. Through lecture and laboratory exercises; students gain understanding of technical principles and test procedures.


Based on: Recommended practice SNT-TC-1A. Alternatively we can provide this training coursebased on EN 473/ISO 9712 or on EN 4179/NAS 410 as well.


Used codes: ASTM E 2375; ASTM E 213; ASTM E 164; ASTM E 797; ASTM E 317; ASME CodeSection V; EN ISO 11666; EN 10160; EN 10228-3; EN ISO 23279; EN ISO 17640; EN 12680-1; EN 12668-3


What you will learn


Training is focused on explanation of basic ultrasonic principles and basic knowledge of ultrasonic standards. Practical part is then focused to recognition, positioning and sizing of indications in welds, forgings, castings and pipes. Trainee will also get knowledge about practical limitations and difficulties which can occur during his practice.


Our courses will prepare you to pass the final exam according to SNT-TC-1A or EN 473 code for Level 1, 2 or 3, to be able to operate manually or on automatic lines typical ultrasonic testing.


UT Level I will be able to test parts according to the relevant standards, recognize size and locate the defects in most types of parts, and report them. Level II certified will be trained to inspect according to applicable codes and specifications; and learn to develop procedures instructions for your in-house applications. Classroom training is accompanied by evaluation of study cases; and by practical tasks with testing and evaluation of samples.


Level I training highlights

Principles of Ultrasonic Testing Evaluation of discontinuities
UT equipment Instrument and sensitivity calibration
UT Methods Vertical Linearity Check
Angle beam and surface wave technique Health Safety and Environment
Immersion technique








Level II training highlights



Demonstrate their understanding of the body of knowledge of the NDT method applications Practical applications (evaluation on components)

Explain the scope and limitations of the method

Select the proper procedure

Select the appropriate equipment and accessories for the employer’s

Select the proper calibration standards to calibrate the equipment

Apply the method and

Interpret and, report and evaluate the results of the NDT



In a direct approach to Level 2, it is necessary to complete both levels = 3 weeks duration. For the applicant having the UT1 L1 course is the general qualification course (1 week) optional.


Other information


Every trainee will obtain a set of educational materials; each course contains many specific training tests (with evaluation) and practical knowledge. Alternatively, we can provide training suitable for candidates working to a written practice based on EN 473 code.


About Certification


The examination and certification process is directly related to qualification system. In case when the training is performed in accordance with EN473 / ISO 9712 the certificate can be issued by independent European certification body DASH CERT.
