A good part and a bad part can look identical from the outside. An internal crack, gas porosity, a shrinkage void or a lack-of-fusion in a weld or casting passes every visual check and then fails in service. You cannot cut every part open to find out. Non-destructive testing (NDT) examines the part and leaves it fit for service. Neometrix engineers the inspection system around the methods.<\/p>\n
– Radiography (RT):<\/strong> casts an internal image onto a digital detector; porosity and voids show as shadows. The X-ray tube, ultrasonic electronics and eddy-current instrument are specialist bought-in items. What turns them into a usable, repeatable, safe system is what Neometrix engineers: the radiation-shielded and interlocked bay, the immersion scanner tank with multi-axis motion, the tube-inspection rig, part handling, automation, imaging and reporting.<\/p>\n
\n– Ultrasonics (UT):<\/strong> pulses sound into the part and times the echoes, locating and sizing a flaw; an automated scan builds a full C-scan map.
\n– Eddy-current (ET):<\/strong> induces a current and reads how a flaw disturbs it, suited to surface cracks and to inspecting heat-exchanger and steam-generator tubes from the inside.
\n– Magnetic-particle (MT) and dye-penetrant (PT):<\/strong> reveal surface-breaking cracks.
\n– Active thermography (IRT):<\/strong> finds debonds in composites.<\/p>\nThe System Is the Engineering<\/h2>\n
