What is Ultrasonic Testing?
Ultrasonic is a high frequency of sound pulses that are emitted from a transducer above a sample. The sound waves propagate through the sample, and reflect at interfaces. The reflected waves are monitored using a detector above the sample. The thickness of the sample, and the depth and type of flaw can be ascertained using this method. The method can be applied to most materials if sound transmission is good. Quick high sensitive results are obtained.
What are the responsibilities of a individual who is certified to Ultrasonic Level 1?
An individual certified to Ultrasonic Level 1 has to demonstrate competence to carry out NDT according to written instructions and under the supervision of Level 2 or Level 3 personnel. Within the scope of the competence defined on the certificate, Ultrasonic Level 1 personnel may be authorised by the employer to perform the following in accordance with NDT instructions:
- Set up Ultrasonic Testing equipment;
- Perform the Ultrasonic Inspection tests;
- Record and classify the results of the tests according to written criteria;
- Report the results
Level 1 certified personnel shall neither be responsible for the choice of test method or technique to be used, nor for the interpretation of test results.
