Welds, castings, and parts used in high stress or high reliability environments utilize Radiographic Testing (Radiography or RT) to detect internal defects not apparent on the surface of the part. We perform x-ray/gamma ray/radar inspection – both film and digital – to MIL-SPEC, ANSI, ASTM and ASME specifications. Radiographic inspection is very accurate and sensitive to internal defects. This is often performed in conjunction with penetrant or magnetic particle inspection for surface coverage.
We can inspect practical thickness ranges up to 3.0” steel.
Liquid penetrant inspection (PT) is a surface inspection method used to test a variety of both metallic and nonmetallic materials such as welds, forgings, castings, plastics, and ceramics. Since liquid penetrant testing is capable of economically revealing surface discontinuities in a variety of dissimilar materials, it is one of the most effective and widely used of all the non-destructive test methods.
The sensitivity of a “penetrant system” is based upon its ability to resolve small defects. The smaller the defect the system can detect, the higher its sensitivity rating. Sensitivity level 1 is low, Sensitivity level 4 is ultra high. NDT Laboratories is capable of performing all types and methods of penetrant inspection.
Magnetic Particle Inspection (MT or MPI) is an inspection method for locating surface or shallow sub-surface defects on ferromagnetic material.
Because of the variety of equipment and materials, there is essentially no limit to the size and shape of parts that can be inspected using MT. MT can be performed on castings, forgings, welds and machined parts, providing that they are of a material that can be strongly magnetized and the surface is sufficiently clean and accessible.
Ultrasonic Testing (UT) is a volumetric non-destructive testing method that uses sound waves to propagate through an object. We perform both contact and immersive UT with capabilities for pulse echo, transmissional, straight beam, angle beam (shear wave) testing, and advanced phased array techniques.
