Phased Array maximum thick.

We inspect forged steel bars up to 10 inches diameter using traditional manual equipments . Somebody could indicate me the maximum thickness that we can check using Phased Array System with the probes present on the market?

Re: Phased Array maximum thick.
Paolo:
If you are now inspecting diameters of 250mm (10 inches) I assume you are using standard manual UT probes typically 25mm. Phased array systems can obviously do the same.

But asking what the maximum thickness possible to test is a bit like asking what is the smallest flaw you can detect. We need more information. Material tested (is the steel forging fine grained or coarse?), test conditions (hot, cold, machined or rough surface?), the applicable Code, are you just looking for a backwall signal or do you have a flat bottom hole target to detect with a specified signal to noise ratio.

With a standard linear array you have the potential to increase the aperture size which is equivalent to increasing the element size of a single crystal probe. Off the shelf you can get a 60 element probe with a 1mm pitch. But to increase the aperture to the full 60mm available with that probe you would need a 64/128 phased array system (32/64 or 32/128 are more common).

Ed

Product Spotlight

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
