A method for inspection of a weld and an inspection apparatus for inspection of a weld |
摘要 |
<p>The invention relates to an inspection apparatus (65) for inspection of a weld (55), the apparatus having a first illumination system (67) to provide a first radiation beam (69) to generate an ultrasonic surface displacement in a weld (55). Further the apparatus has a second illumination system (73) to provide a second radiation beam (75) at the weld (55) and a detector (77) for receiving the reflections (79) from the second radiation beam (75) and to detect the ultrasonic surface displacements at the weld (55) caused by the first radiation beam (69) from the reflection (79) of the second radiation beam (75) on the detector (77).</p> |
