Training methods
NDT are based on the principles of Physics and examine the surface and the interior of pieces and constructions without harming their serviceability. The equipment and the consumables required can be easily transported and have low to medium cost.
Indications like the accumulation of magnetic particles (MT), the bleed out of penetrant (PT), the returning ultrasound signal (UT) and the disturbance of electric fields, inform us about the nature and the severity of the findings.
Training, experience and knowledge of the part under testing, contribute decisively to the outcome and reliability of the inspection.
Next we shall present the basic Non Destructive Testing methods, with emphasis to the applications, the advantages and the limitations of each method (radiography, penetrant testing, magnetic particle testing, eddy current testing and ultrasonic testing).
