Detection of Linear indications

I am experiencing difficulties in detecting the fine linear indications ( could be Lack of fusion or crack) before stress relieving. The same indications are prominently seen after SR in Ultrasonic Test.

The joint is between two angularly paced placed Carbon Steel Plates and one of them is overlayed with SS.

I would be grateful for suggesting some solution to this.

I am not familiar with the configuration you are talking about, but are the indications appearing anywhere near the stainless to carbon steel interface? Are you using shear waves? If you answered yes to both questions you may want to try using refracted longitudinal wave search units.

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

s. This projector incorporates design and safety features that make it flexible, compact and lightweight. The Projector is lighter than most of its competitors. It incorporates an improved source channel, based on a new helicoidal design, which makes maintenance easier. The helicoidal design also allows smoother movement of the source assembly inside the device, making it easier for the operator and improving safety. The Projector also has a unique safety feature not found in competitive products. The source assembly locking mechanism is triggered by the source holder capsule at the front of the source assembly, thereby always assuring the operator that the source has returned to the safe position. The Exertus Dual 120 is ISO3999:2004 compliant.
