NDT exam question

I enterd my company NDT exam and I faced question I couldnt give answer for it regarding dye pentrant for aviation ? I get 71% fail so please help
are my answer correct
1- Are the black light and UV light the same or diffrent ? my answer was diffrent
2-titanuim inspetion use which type of dye?my answer was florocent
3- which matarial pest inspected with dye (para magmetic-hard steel -alcladed aluminum) my answer para magnetic

Re: NDT exam question
UV light means electromagnetic radiation from 200nm to 400nm wavelenght (under 200nm you have vacum UV).
Black light is comonly used to refer to the UVA (UV band A light), this is from 315nm to 400nm, wich is the used for the fluorescent tests (with the peak in 365nm, that is the wavelenght that allows the fluorescence fenomenum)

Varex Imaging Large Field of View (FOV) Digital Detector Arrays (DDAs)

A larger FOV DDA can reduce the space and volume of the X-ray inspection system on the factory floor
...
, enable faster scanning times, better throughput and better resolution images at a lower dose. Customers can also save time and money. With these benefits in mind, Varex Imaging has designed a family of large FOV detectors (4343HE, XRD 1611, 4343DX-I, 4343CT) for our industrial imaging customers.

FMC/TFM

Next generation for Phased Array UT is here now with FMC/TFM! Have higher resolution imaging, impr
...
oved signal to noise ratio, characterize, size and analyze defects better with access to several wave mode views and save raw FMC data for higher quality analysis.  Some of the benefits are:
  • Beautiful Image! Easier to understand what you're looking at
  • Completely focused in entire image or volume
  • Much easier to define setups before inspection
  • Easier to decipher geometry echoes from real defects
  • Oriented defects (e.g. cracks) are imaged better
  • See image from different wave modes from one FMC inspection
  • FMC data can be reprocessed/analyzed without going back to the field

SITEX CPSERIES

Teledyne ICM’s CPSERIES has been designed with a view to revolutionizing the handling and perfor
...
mances of portable X-Ray sets. Despite having managed to halve the weight of similar portable X-Ray generators available on the market (while continuing to provide the same power output), the SITEX CPSERIES generators feature a shutter, a laser pointer, a beryllium window, an aluminum filter and two integrated diaphragms (customized sizes are available upon request). Without compromising the robustness and reliability for which ICM products are renowned, the small size and light weight of the SITEX CPSERIES will radically change the way that you perform your RT inspections. And you will see a positive impact in terms of both quality and return on investment (ROI).
