AB The most common nondestructive weld inspection technique is X-rays and, since a fewyears ago, the ultrasound-based phased array. Their comparison has been done from the top view ofboth, with the result that the phased array is much more efficient in discovering flaws. From the laststudies of the authors, a welding flaw can be three-dimensionally reconstructed from the sectorialphased array information. The same methodology is applied to compare quantitatively X-rays andphased array on 15 metal inert/active (MIG/MAG) welding specimens covering pores, slag intrusionand cracks. The results can be summarized in the correlation of the top views and in the correlationprofiles between the X-ray top-view and the reconstructed top-view at the depths from phased arrayin the weld. The maximum correlation is the depth when the flaw in the X-ray looks like that in thephased array records at some depth, leading to an effective quantitative comparison of X-rays andphased array.
