The concept of weld inspection is shown
below. A probe is selected that illuminates the weld as shown below. In
the first leg, only the bottom half of the weld is illuminated.
However, with reflection from the ID surface the entire weld is illuminated and
the complete weld volume can be inspected. For example, the indication ‘a’ in
the weld is detected by the reflected sound and displayed as the mirror image
‘a-’ in the second leg. Similarly other flaws are displayed in the
image.
Concept of phased arrays for Weld Inspection. Indication ‘a’ detected by the reflected beam is displayed as a mirror image ‘a-‘ in second leg
Examples of defects images detected in welds are shown below.
