Nondestructive Testing (NDT) Companies in the U.S.

NDT labs inspect parts and welds without damaging them, using ultrasonic, radiographic, magnetic particle, dye penetrant and eddy current methods to find cracks, porosity and inclusions. The labs below list nondestructive testing.

Listings come from each company’s public information and may be incomplete, so confirm capabilities, materials and certifications with the shop before you commit. The fastest way to get quotes is one request: attach your drawing (PDF or STEP) or describe the part, and Noramark routes it to U.S. shops that fit.

The most listings are in California (27), Texas (23), Ohio (14) and Illinois (13). Certifications stated: 51 ISO 9001, 37 AS9100 and 25 Nadcap.
