Methods of depth evaluation

Laminography as a 3D-method

Planar Tomography for 2D-reconstruction (Cross section reconstruction)

Fig 5: Principle of planar tomography. The X-ray tube is shifted alog the surface parallel to the pipe axis and several hundred projections are taken for reconstruction. Fig 6: Reconstructed profile of a circumferential weld of an austenitic pipe after oscillation

Determination of wall thickness
