NDT Bridge surface
NDT Bridge surface
(OP)
Hi All
I have a problem where a trapezoidal channel has been welded to the underside of a bridge surface, the upper surface has a layer of tar that cannot be removed. We have been asked to carry out a NDT on the area where the surface meets the channel on the inside. See attached
Does anyone know of an ultrasonic method of testing this area, we have 150 metres to test.
Thanks in advance

If it's cracking do you expect through cracks?

The contractor was awarded a minor contract for 15 days,but eventually turned out to be over 6 months and he was not compensated.

Unfortunately the trapezoidal section is not large enough for an inspector to crawl through, I will discuss rustbuster's suggestions with our NDT contractor.
Thanks for the heads up unclesyd, we will not commit ourselves to repair work without qualifying the quantities.
