UT of AL rod

we want inspect a lot of Al rod(solid bar) with UT inspection to detect internal defect in it. the OD of rod is 30mm and 3m length.what's your suggestion?contact or immersion?manual or auto?why and what?

Hello Mohsen,
'a lot' is not a quantifiable amount. 20 bars might be a lot also 10,000 could be a lot, 1,000,000 is definitely a lot.

if it is going to be an on-going inspection then an automated UT immersion system would be the most cost effective option.

The best way is to determine if a manual or automated inspection is best (meaning most cost effective) is to test a small number manually and work out the inspection cost per length. Then obtain the price for an automated system and divide the cost of the automated system into the number of bars that you wish to test. compare your results.

GUL QSR1® Scanning

How do you measure pipe wall thickness without direct access to the area? QSR® Scanning - Guide Wav
e Quantitative Short Range Scanning.


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
