Phased Array to D1.1

Does anybody know if AWS D1.1 has accepted the use of phased array for existing welds??? Any information would be much appreciated. Thanks

D1.1 makes no provisions for it, but also does not disallow it. There is an appendix in the back of the book that allows other UT techniques, if they can be proven by locating artificial flaws. This is how small transducers are allowed for use, when the smallest listed in the main body is 5/8" x 5/8". This deviation also requires the specific approval of the structure's engineer. Should be easy to obtain, after you demonstrate the exceptional ability of Phased-Array compaired to manual scanning.

The appendix is "Annex K" in the 2004 edition of D1.1

Would it be AWS D1.1 2010 Annex S?

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).
