In real-time detection of weld of straight
welded pipe, there is no need to rotate the pipe when the pipe is
moved by transmission vehicle. The X-ray flat panel detector is
used to absorb X-ray photons that pass through the welded pipe,
and convert them into electronic data. The electronic data is then
sampled and transformed into sequence of images by image
acquisition grabber and the sequence of images is transmitted
to the computer for processing and display.
