UT vs RT (ASME 31.3,31.11)

All,

We currently are using RT for circ and long seam welds on piping products, various diameters. When we bring in RT, there is the obvious time for setup, shutting the shop down due to the radiation safety etc. We have approval from the customer to perform UT in lieu of RT therefore, would there be a time savings to UT instead of RT? I know it is a lot more involved to bring an RT crew in to shoot the weld, develop and interpret film as compared to a UT tech scanning the weld. I'm curious to hear everyone's thoughts?

Thanks,

Manual UT interpretation is only as good as the ability of the person performing the UT.
RT will give a permanent record for anyone to review at a later date.
With the automated UT and the records they can provide that removes the technicians ability from the equation so it seems the best way to go for the future.

It really depends on the welds if you are faster or not (complicated geometries vs. basic butt welds).
In the beginning it sure will take longer till you have everything figured out, calibrated and set up, but after that time basic welds, especially in the shop, will be done in no time and your hard work of preparation will pay off. (Im only talking about phased array scans here).
