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.

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).
