Non-destructive test workers

The non-destructive testing are the complex of tests that are conducted to asseverate the quality of components and products without altering the structure and characteristics of materials.

The testing through non-destructive tests is very important to detect the soundness of the components, to identify the malfunctioning of machinery or ensure the soundness of items processed.

For liability that the outcome of these tests involves, it is expected that workers are certified in order to guarantee competence and experience.
