Non -destructive
The methods ensure that materials or components undergo no harm during testing. They allow for multiple inspections without affecting the subject.
Ultrasonic Tests
Using ultrasonic NDT equipment testing people sends high-frequency sound wave pulses into materials. These waves then reflect off any internal flaws like voids or cracks. The equipment then analyzes the reflected waves and displays them as a visual graph. Inspectors then interpret this data to identify the detected defects' location and size.
Magnetic Particle Inspection
An inspector begins by magnetizing the test material. They then apply a magnetic particle mixture to the surface. The resultant detectable patterns then show any surface or near-surface discontinuities.
Radiographic Testing
The technician places a radiation source or gamma on one side of the material. They then put a radiographic film or digital detector on the other side. As the radiation passes through, denser areas like welds or metal cracks will appear darker on the film. The movie will then show the internal structure of the material.
Regular Calibration
NDT equipment calibration helps maintain that the tools provide accurate readings. It also helps avoid them from giving erroneous results that could lead to dire consequences.
Periodic software updates
Software-based NDT tools require periodic updates to ensure the tools perform optimally. Outdated software often lacks bug fixes, which makes it more challenging to keep the equipment secure.
