Sub-surface discontinuities are detected by transmitting X-rays or Gamma rays through a material to a film on the opposite side of the piece being tested. Radiography works on both ferrous and non-ferrous materials. Magna Chek has several Radiographic capabilities: X-Ray, Real Time X-Ray, Gamma Ray and Mobile NDT units. Whatever your needs, Magna Chek can assist you with them.
X-ray:
With Magna Chek’s 200 and 300 kilovolt x-ray units, maximum thickness penetration is 2.5inches of steel. But it offers an even greater thickness penetration when inspecting aluminum, plastics, ceramics and other certain materials, depending on their density. We have a 12x12 foot exposure room with a sliding lead doorwall that is capable of inspecting very large pieces. Testing in this room uses the 300kilovolt x-ray unit for maximum penetration and greater versatility. With this large exposure room we can test a wide variety of large parts such as steering components, aircraft assemblies, armored vehicles, turrets and more. We can also test large lot sizes of castings, forgings, solid state components, etc.
Real Time X-Ray:
Magna Chek uses the BI-VISION video digital image processing system. This system sets the standard for industrial real time x-ray image enhancement. With its high resolution, speed and advanced image manipulation features, the BI-VISION system provides quick and accurate detection of the most subtle defects from the x-ray image up to 2.5inches of steel. This system provides a wide range of image processing functions that are easily accessed through the touch screen menus. Features include frame averaging, recursive frame averaging, contrast, black and white levels adjusting, image overlay labeling and pseudo color. A range of 2 to 264 frames of video can be integrated and average to reduce white noise caused by x-ray scatter. Image convolution features include image sharpening, smoothing, edge detection, edge enhancing and more. The on-screen distance measuring feature allows easy evaluation of the sizes of image indications. Images can be output to RS-170 or SVGA monitors, stored to disks or other digital storage media or printed. All of these capabilities and more, make the BI-VISION digital image processing system ideally suited for integration in to NDT radiography applications.
Gamma Ray:
With Magna Chek’s Gamma Ray unit, we increase penetration capabilities up to 3.5 inches of steel. Gamma ray units do not require power because of the Iridium isotope, which makes them ideal for inspecting remote items such as pipelines, bridges, etc.
Mobile NDT Units:
Can’t come to us? Then Magna Chek will come to you. Our units can be equipped with 200 or 300 kilovolt X-Ray machines or Gamma ray units – whatever your spec requires. On site development, interpretation and reporting are standard with Magna Chek. These units are available for on-site inspection of power generating turbines, boilers, pressure vessels, bridges, crane assemblies and much more.
