ULTRASONIC TESTING

WHAT IS ULTRASONIC TESTING? 

Ultrasonic Testing (UT) is a group of nondestructive examination (NDE) techniques that use short, high-frequency ultrasonic waves to identify flaws in a material. They generally work by emitting waves into a material and the returning waves are analyzed. If an impurity or a crack is present, the sound will bounce off of them and be seen in the returned signal.

 

By measuring these waves, the properties of the material and internal flaws can be identified. There are several physical parameters to understand such as propagation, reflection, refraction, attenuation of sound, responses from discontinuities, acoustic impedance, absorption, and sound characteristics. 

WHY SHOULD I CONSIDER A CAREER IN ULTRASONIC TESTING?

UT is used for the inspection of castings, forgings and welds in manufacturing or inservice testing across all industry sectors. It has a high penetrating power, high sensitivity, highly accurate in determining reflector position and estimating size and shape, minimal part or specimen preparation, portable equipment provides instantaneous results, detailed images can be produced with automated systems. 

ULTRASONIC TESTING COURSE - LEVEL I (UT1)

The UT1 course will provide you with the basic theory and practical knowledge about ultrasound inspection.  You will learn key concepts, mathematical relationships, the equipment required to perform the technique, the testing method, how to calibrate the equipment, and the procedures required.

WHY SHOULD I STUDY UT1? 

This course is designed for people interested in making a career in Ultrasound Testing and Inspection.   It is intended for operators, inspectors and technicians responsible for practical application of testing, inspection and writing techniques and instructions for detection of flaws in various types of material across all industry sectors.  

 

UT1 is your first course in your career path.   You will be able to set up the equipment, perform the tests, record them and classify the results.   You should start to report the results.   

Level 1 are technicians qualified to perform calibrations and tests with supervision and direction by higher level personnel. 

 

UT Positions even at entry-level generally require specialized training.   Also the career growth in the future looks bright for UT professionals since the NDT industry will continue to grow substantially.  Also UT professionals can choose to spend the entirety of their career in this industry and maybe expand to other techniques as well.   There’s unlimited room for advancement.
