Phase Array Phasor XS

Date 08-09-2009 14:11

Phasor xs is a brand name, not a method.
Your question would then be Phased array Ultrasonics vs. Radiography.

UT in general will have a higher probability of finding planar flaws. (cracks, lack of fusion)
RT will do a better job of finding volumous flaws. (porosity, slag)

Most codes require Automation for UT code exams.
RT does not.

The closest equivelent to AUT/PAUT is Computed Radiography.
The same percentages and flaw types apply as for basic UT/RT with the exception of the overall POD increasing dramatically.

The codes, standards, and specs that apply to your project should take precedence over opinion.

Dear CWI555

thank you very much for your input.
our project is to follow ASME Code IX standard
but they intreduced this (phased array) to our project if it's good, we could go for it
i really appreciated your input & the information you provided

wish you all the best

ASME Section IX covers your welding procedures and welder qualifications. What is your construction code? What are you actually building? There are certain rules that must be folowed by most contruction codes
in order to perform UT in lieu of RT.

For example, ASME B31.3 has a code case (B31 case 181) that descirbes the methods and acceptance criteria. You don't really want to perform Phased Array or TOFD using an RT Aacceptance criteria. You will end up repairing everyuthing.
